The Links Between Growth And Energy Consumption Environmental Sciences Essay

Melting glaciers, lifting sea degrees, an addition in mean planetary temperature, and unnatural precipitation forms have started to do planetary warming an evident world throughout the past decennary. Meanwhile, increasing gross domestic merchandise ( GDP ) remains the cardinal mark of the universe ‘s economic development scheme. In many states, GDP growing is tied closely to increasing energy strength. Unless economic growing is decoupled from increased energy ingestion, the horn of plenty of nursery gases in the ambiance and the subsequent consequence of planetary heating will halter political and societal facets of the universe ‘s activities today. Harmonizing to the Alliance to Save Energy, â€Å" energy efficiency is the quickest, cheapest, cleanest manner to widen our universe ‘s energy supplies. † Because enormous energy losingss occur in the out-of-date substructure, energy efficient solutions that can assist uncouple economic growing from wasteful en ergy usage must be applied. Tamil Nadu is a fast developing province that supports a population of over 6 million people. With the addition in population comes an addition in demand for basic comfortss that include H2O, shelter and lifestyle demands. The growing in population should be supported with a attendant rise in the Gross Domestic Product of the province for the province to be self sufficient in footings of its resources. However, unlike the population, resources do non increase exponentially and therefore, the displacement in the demographic profile of the province will further increase the demand for non-renewable supplies. This calls for the efficient usage of available resources so that a dearth free hereafter can be attained in footings of energy and H2O demands. The province ‘s Annual Plan shows that every twelvemonth, around 1,94,351 hundred thousand rupees is being spent for bring forthing and keeping power supplies. The ratio of this demand to the other disbursals of the province is listed in the tabular array below. Efficient usage of available energy will assist cut down this outgo and this money can be channeled to other constructive strategies such as instruction or the wellness sectors that warrant more budget allotments. Harmonizing to the International Energy Agency ( IEA ) , energy strength in high because of two grounds â€Å" higher losingss in the supply concatenation and inefficient usage. † ( IEA 2003 ) . Implementing energy efficiency steps in substructure is a guaranteed method for bring forthing energy and fiscal nest eggs from edifices, warming, H2O supply, sewerage, and street lighting substructure. Energy efficiency in H2O supply systems is particularly good: nest eggs are accrued in H2O every bit good as energy, cut downing costs while bettering service. Efficiency in the proviso of energy and H2O is one of the few cost-efficient options available for run intoing turning demands for critical services such as electricity, H2O and effluent intervention. Energy efficiency retrofits contribute to improved wellbeing of the population, client service and payment aggregation. If increasing energy efficiency is seen as a end on a nation-wide graduated table, it can besides lend to a state ‘s energy security, be it energy exporting or energy importation. Presently, substructure is outdated. In visible radiation of the uproar over planetary clime alteration and the lifting tendency in green investing, pulling attending to energy efficiency is a timely and valuable chance. There are legion illustrations of successful energy efficiency undertakings to back up the averment that efficiency betterments yield cost-efficient benefits. Such illustrations were highlighted in the Commonwealth of Independent States † held in Moscow, Russia 13-14 November 2006. This demonstrates that due to miss of professional edifice direction, economic inducements for rational energy ingestion and metering, much energy and fiscal resources that can otherwise be usedare being wasted ( Sivaev 2006 ) . Power Grid of the province: LENGTH OF EHT/HT LINES, DISTRIBUTION TRANSFORMERS AND EHT/HT SUB STATIONS 2008-09 Tamil Nadu has a power grid that has a entire affiliated burden of 41,713 million units of electricity which is distributed throughout the province for domestic, commercial, industrial, public utilities, agribusiness, grip and railroads. The per centum of energy ingestion for each of these intents in enlisted in the tabular array below. Consumption OF ELECTRICITY 2008-09 A really little proportion of the generated power is sold to other provinces. Among the sum split up explained above, the highest per centum of power ingestion is by the domestic sector after the industrial ingestion. The power grid of the province caters to 1,36,64,219 families with a power burden of 15,599 million units as per the main applied scientists be aftering study, TNEB, Chennai for the twelvemonth 2009. The sum of electricity for the other sectors is besides detailed in the undermentioned tabular array. Consumers AND CONNECTED LOAD The hereafter of lodging and shelter are houses that are designed to increase the energy efficiency and environmental public presentation. The long-run aim is to transform the lodging market to one in which a bulk of residential new building in the province is â€Å" net zero-energy † i.e. highly efficient edifices whose low energy demands can be met by on-site renewable energy coevals. It is critical to back up the passage to a residential new building energy codification that favours energy preservation criterions to guarantee a better tomorrow ( Building Science Consortium, 2009 ) . Power Dearth in Tamil Nadu: To understand the nature of the power famine in tamilnadu, it is critical to understand the beginning of the power that is generated. In tamilnadu the net energy generated comes from the thermic workss, hydro-electric workss, Wind/Solar energy generated within the province. However this histories for merely around half the demand of the province, and therefore the remainder is purchased from the cardinal sectors, CPP and private sectors. The split up of the generated power is shown in the undermentioned figure. There are a figure of market barriers to efficiency investings in new building, viz. : conflicting design standards, deficiency of information sing the benefits of efficiency and environmental public presentation on the portion of consumers, builders, loaners, valuators, Realtors and others, limited proficient accomplishments on the portion of some of the builders and their subcontractors to turn to cardinal elements of efficiency ; and inability of consumers, loaners, valuators and others to distinguish between efficient and standard places. Low-carbon energy in edifices Low-carbon energy issues in the built environment have been a cardinal focal country for REEEP since the G8 Gleneagles Plan of Action in 2005, which called for REEEP to make more work in the countries of energy efficiency in edifices. Since so, REEEP has been back uping both energy efficiency and the integrating of renewable energy in edifices, holding supported six undertakings and committed about a‚ ¬0.6 million in this infinite. The REEEP-supported undertakings in low- C energy have covered four states: China, Fiji, South Africa, and India. Some of the cardinal enterprises supported by REEEP include the followers: Financing the publicity of energy efficiency in China by Energy Research Institute of the National Development and Reform Commission ; Promotion of energy efficiency in the cordial reception sector in Fiji by the Greenlight Technology Group ; Policies and ordinances for constructing energy efficiency in Bangalore, India, by the Energy and Resources Institute ( ERI ) . Cardinal lessons from REEEP ‘s experience in low-carbon energy in edifices include the followers: Solar level home base aggregators are a mature, appropriate, financially feasible, and ready engineering for a large-scale rollout in developing states ( Winkler, 2007 ) . Appliance criterions and labels are a really effectual policy and regulative instrument. Their function will increase as people in developing states progressively get energy-consuming equipment such as iceboxs, air conditioners, rinsing machines, etc. There is besides a demand to spread out the range of criterions and labels to include thermic energy contraptions such as gas room warmers and gas cookery ranges. The direct and indirect subsidies on electricity and warming fuels are a major barrier to accomplishing low-carbon energy passage in edifices in developing states ( Srivastava and Rehman, 2006 ) . Reform of administered monetary values and rationalization of subsidies in electricity and fuels are a pre-requisite to accomplishing important additions in energy efficiency and renewable energy in the built environment ( Johannson and Goldemberg, 2002 ) . Cardinal lessons from REEEP ‘s experiences in low-carbon energy policy include the followers: The figure of people populating in urban Centres in developing states is increasing, and more urban Centres are being developed. Cities and towns provide a good chance to passage to a low-carbon energy system through a focussed, area-based attack. Low-carbon energy planning demands to be integrated into urban planning and should cover subjects such as transit, edifice, and H2O supply every bit good as electricity and heat. Policy instruments such as feed-in-tariffs have helped in increasing the portion of renewable energy in electricity systems. However, feed-in-tariffs should be carefully designed to guarantee economic efficiency and long-run nutriment of the renewable energy market. Feed-in-tariffs are non relevant to off-grid energy systems, thermic energy, or energy efficiency market development. Mechanisms such as command systems and certificate systems ( renewable energy certifications, white/EE certifications, etc. ) provide an alternate market-based mechanism, but new institutional models should still be established before they can be implemented. Buildings energy public presentation criterions and codifications are cardinal policy instruments for low-carbon energy passage in edifices. Corporate policy and corporate societal duty have non played a important function in low-carbon energy grade development in developing states. As traditional and new concerns grow in developing states, the function of corporate policy will increase, comparative to authorities policies. Several describing enterprises, such as the Carbon Disclose Project ( CDP ) supported this determination. Single household and joint-family places can both profit if the place is designed to be energy efficient. An of import restriction is constructing â€Å" Low-cost Housing † regardless of their location. Larger places as in places designed for joint households are likely to inherently utilize more energy, and advancing energy efficient lodging allows entire place energy usage to turn with size ( Building Science Consortium, 2009 ) . A concerted selling offer for take parting builders will drive homebuyer demand for measure uping places. An aggressive consumer focused selling run will be indispensable to keep builder engagement ( and hence market portion ) . Areas for research in residential new building may include the public presentation metering of plan places and optimized new place designs for important decrease or riddance of chilling energy requirements.it is besides critical to see chances to beg originative proposals for pilot-scale publicities associated with the development of energy efficient places. Energy ingestion metres and monitoring will be built into these places to enable future trailing of existent public presentation. To run into the challenges of a slow residential new building lodging market, increased energy criterions, reward high public presentation places, passage to a market-based, place energy rater web, the undermentioned plan schemes and tactics are being proposed: Carbon footmark labelling for high public presentation places, making consumer consciousness and demand, distinguishing builders in the turning â€Å" green edifice † consciousness of consumers. It is critical to pull media attending to relevant undertakings and associated nest eggs realized by occupants, particularly for place undertakings, which incorporate both energy efficiency and renewable energy engineerings ( hypertext transfer protocol: //www.buildingscience.com ) . Further, it is of import to construct relationships with residential builders through educational seminars and preparation to increase higher public presentation edifice patterns and to assist construct a Green Workforce. Energy-efficient places help lower energy costs, addition affordability, addition lastingness, and better wellness and safety. High public presentation places cut down impact on the environment. It is a call for every place to be a portion of the solution for sustainable life to assist battle planetary heating. Feature narratives concentrating on energy and fiscal nest eggs, new engineerings ( solar ) , and environmentally sound edifice patterns herald a new epoch of efficient places. Homes that feature new energy-saving engineerings, renewable energy, and really high public presentation places, in footings of their energy evaluation and decreased environmental impact give us a promise for a better life in the hereafter ( Home Energy Magazine ( for residential consu mers ) , 2008 ) . Increased consciousness of green and sustainable life patterns, and impact of C footmark decrease, greater consciousness of residential indoor air quality, wellness and safety issues for better life, publicity of energy rescuer programs to cut down energy use 20 % back uping the increased development of a green work force by advancing green occupation preparation are critical stairss towards accomplishing an ecofriendly building civilization. The current economic uncertainness may stamp down Numberss of energy efficient places, peculiarly if occupants are non good educated on the benefits of such places. As such, the consciousness of energy efficient places among Realtors and residential place buyers/builders remains comparatively low ( Home Energy Magazine ( for residential consumers ) , 2008 ) . Energy Efficient Strategies in edifices: Energy efficiency steps require capacity-building attempts to authorise establishments and persons to implement energy-saving plans and do energy-saving determinations. Examples of capacity edifice include set uping energy audit processs and hearer preparation plans, developing systems to track energy ingestion forms and set up benchmarks, set uping energy direction systems, making enfranchisement systems for energy practicians, developing energy direction guidelines, and easing engineering transportation. Passive Solar Passive solar systems integrate solar air heating engineerings into a edifice ‘s design. Buildings are designed with stuffs that absorb or reflect solar energy to keep comfy indoor air temperatures and supply natural daytime. Floors and walls can be designed to absorb and retain heat during warm yearss and let go of it during cool eventides. Sunspaces operate like nurseries and gaining control solar heat that can be circulated throughout a edifice. Trombe walls are thick walls that are painted black and made of a stuff that absorbs heat, which is stored during the twenty-four hours and released at dark. Passive solar designs can besides chill edifices, utilizing blowholes, towers, window overhangs, and other attacks to maintain edifices cool in warm climes ( Doug Rye, 2010 ) . Air Waterproofing Air sealing the place â€Å" envelope † and sealing air distribution canals are two of import steps for energy efficiency and indoor air quality. The greatest air escape waies are at the margin of the floor line and in air distribution ducts/returns. Air escape besides occurs at incursions for plumbing, illuming, wiring and around chimney pursuits. Conditioned air leaking from canals can do the full house to pull outside air. This replacing air must be conditioned on a go oning footing, increasing energy usage. Merchandises for sealing air escape in place building include froth sealer for wiring holes in the top home bases of walls ; caulk for clefts and crannies ; weather-stripping for doors and Attic hatches ; and backer rod or rope caulk for make fulling window/door shim infinites. Insulation Some insularity merchandises perform dual responsibility by air sealing and insulating in topographic points where they are applied. As the thickness of an insulating stuff additions, so does effectiveness or R-value. However, if air flows through the insularity, or finds a tract around the insularity, the insulating consequence is greatly reduced. That ‘s why air sealing the edifice envelope before insulating is of import. Types of Insulation Cellulose: R-value is about 3.4 to 3.8 per inch. Cellulose, which is made from recycled newspaper, is blown moistness into unfastened wall pits and sometimes blown dry in the Attic. Boric acid, an additive in cellulose insularity, increases fire opposition, repels insects, and helps forestall mold growing. Cellulose should be blown at a denseness of around 3 to 3.2 lbs per three-dimensional pes to assist forestall subsiding and for enhanced air sealing. Mention to the coverage chart on each bag and cognize how many bags are installed. Fiberglass: R-value for batts is about 3.1 to 4.3 per inch. Compaction of batts will do a decrease in R-value. Fiberglass insularity provides small decrease in air escape, but when combined with extended air sealing patterns can be really effectual. Some new methods of put ining fibreglass include a more heavy high R-value application utilizing an adhesive binding agent and a nonwoven cloth for keeping. Spray-in-place froth: R-Value scopes around 3 to 4 for unfastened cell froth and about 6 to 7 per inch for closed cell froth. Foams have high value for insulating and have excellent air sealing belongingss. However, spray-in-place froth has a higher initial cost. Flammability and burning features of froth merchandises vary harmonizing to the chemical preparation, burning temperature, and available air. WINDOWS, DOORS AND SKYLIGHTS For energy efficiency and comfort, choose ENERGY STAR Windowss, doors, and fanlights labeled for your clime zone. To measure up for the excess benefits of Comfort Advantage Plus, select a window with a Solar Heat Gain Coefficient ( SHGC ) of.35 or lower. This ensures extra protection from solar heat come ining the place ( hypertext transfer protocol: //www.efficientwindows.org/index.cfm ) . Light ENERGY STAR qualified illuming provides warm bright visible radiation but uses 75 per centum less energy and produces 75 per centum less heat ( Journal of Light Construction ( for builders or contractors ) , 2008 ) . Both bulbs and illuming fixtures exposing the ENERGY STAR label can be used ( hypertext transfer protocol: //www.energystar.gov ) . Lighting histories for about 20 % of the entire electricity demand in the state, and is a major constituent of the peak burden. The bulk of illuming demands in the state are met by incandescent bulbs, peculiarly in the family sector, which are highly energy inefficient as over 90 % of the electricity is converted into heat, and merely upto 10 % is used for illuming. CFLs provide an energy-efficient option to the incandescent lamp by utilizing one-fifth as much electricity as an incandescent lamp to supply the same degree of light. CFLs have about wholly penetrated the commercial market, and the gross revenues of CFLs in India have grown from about 20 million in 2003 to around 200 million in 2008. Statisticss by illuming association indicates that the incursion of Compact Fluorescent Lamps ( CFLs ) in family sector is merely approximately 5 % – 10 % ; the comparatively low incursion rate is mostly due to the high monetary value of the CFLs, which costs 8-10 times every bit much as incandescent bulbs. It is estimated that about 400 million light points in India today are lighted by incandescent bulbs ; their replacing by CFLs would take to a decrease of over 10,000 MW in electricity demand. This would non merely cut down emanations by manner of efficient terminal usage of electricity, but would besides ensue in the decrease of extremum burden in the state which presently faces a deficit of upto 15 % . The Conference of Chief Ministers on Power Sector chaired by the Hon'ble Prime Minister on 28th May, 2007, recognized the important potency of salvaging electricity through its efficient usage by Demand Side Management intercessions which would supply immediate consequences for salvaging electricity. The intercessions resolved by the Conference include bulk procurance and distribution of CFLs ( to cut down costs ) , acceptance of Energy Conservation Building Code ( ECBC ) , advancing and mandating the usage of energy efficient pumps and other energy efficient and contraptions. The â€Å" Bachat Lamp Yojana † aims at the big scale replacing of incandescent bulbs in families by CFLs. It seeks to supply CFLs to households at the monetary value similar to that of incandescent bulbs and programs to use the Clean Development Mechanism ( CDM ) ofthe Kyoto Protocol to retrieve the cost derived function between the market monetary value of the CFLs and the monetary value at which they are sold to families. The Bachat Lamp Yojana is designed as a public-private partnership between the Government of India, private sector CFL providers and State degree Electricity Distribution Companies ( DISCOMs ) . Under the strategy merely 60 Watt and 100 Watt incandescent Lamps will be replaced with 11- 15 Watt and 20 – 25 Watt CFLs severally. BEE will supervise the electricity nest eggs in each undertaking country in conformity with the monitoring methodological analysis prescribed by the Executive Board of the CDM. For this intent, BEE has developed smart metres based on GSM engineering that are fitted between the socket and the CFL in sample families in each undertaking country. The GSM based metre collects the information on hours of usage and energy consumed by the sample CFL and sends this information by SMS to the cardinal waiter. An independent bureau has already been selected for this occupation and metres have been installed in Vizag, Andhra Pradesh and Yamunagar, Haryana. Trial of these metres have been carried out in NABL accredited labs. It is expected that around 50 hundred thousand CFLs will be replaced in each DISCOM country. In order to cut down the dealing costs associated with the blessing of CDM undertakings, BEE has developed a Programme of Activities ( PoA ) which would function as an umbrella CDM undertaking, and would be registered with the CDM Executive Board. The single undertakings, designed to be in conformity with the umbrella undertaking, would be added to the umbrella undertaking as and when they are prepared. The development of the PoA is a voluntary action on the portion of BEE, and it would non seek any commercial or CDM grosss from the PoA. On the other manus, BEE will, on behalf of the Government of India take the duty of monitoring of all undertaking countries after the DISCOMs and the CFL providers have entered into a three-party understanding ( TP A ) with BEE. Solar Power Solar power is energy from the Sun. Solar engineerings convert visible radiation and heat from the Sun into utile energy. Photovoltaic ( PV ) systems convert sunlight into electricity. Thermal systems cod and shop solar heat for air and H2O warming applications. Concentrating solar power systems concentrate solar energy to drive large-scale electric power workss. Solar power systems produce small or no emanations and have a minimum impact on the environment. Photovoltaics PV power systems convert light from the Sun into electricity. PV cells are devices made of semiconducting stuffs similar to those used in computing machine french friess. When these devices are connected to an electrical circuit and exposed to visible radiation, they release negatrons that flow through the circuit, making an electric current. PV panels, are devices that contain a variable figure of PV cells and change over sunshine into direct current ( DC ) electricity. PV panels are typically incorporated into systems that combine batteries and electronic control equipment to supply full- clip DC and/or jumping current ( AC ) power. Typical applications include illuming, electronics, telecommunications, and small-scale H2O pumping.THE RATIONALE FOR PVSolar energy is the most abundant energy resource on Earth. The solar energy that hits the Earth ‘s surface in one hr is about the same as the sum consumed by all human activities in a twelvemonth. Direct transition of sunshine i nto electricity in PV cells is one of the three chief solar active engineerings, the two others being concentrating solar power ( CSP ) and solar thermic aggregators for warming and chilling ( SHC ) . Today, PV provides 0.1 % of entire planetary electricity coevals. However, PV is spread outing really quickly due to dramatic cost decreases. PV is a commercially available and dependable engineering with a important potency for long-run growing in about all universe parts ( Bank Sarasin, 2008 ) .Technology public presentation and costPV systems straight convert solar energy into electricity. The basic edifice block of a PV system is the PV cell, which is a semiconducting material device that converts solar energy into direct-current ( DC ) electricity. PV cells are interconnected to organize a PV faculty, typically up to 50-200 Watts ( W ) . The PV faculties combined with a set of extra application-dependent system constituents ( e.g. inverters, batteries, electrical constituents, and mounting systems ) , organize a PV system. PV systems are extremely modular, i.e. faculties can be linked together to supply power runing from a few Watts to 10s of megawatts ( MW ) . Commercial PV faculties may be divided into two wide classs: wafer based c-Si and thin movies. There are a scope of emerging engineerings, including concentrating photovoltaics ( CPV ) and organic solar cells, every bit good as fresh constructs with important possible for public presentation addition and cost decrease ( Fthenakis V. et al. , 2008 ) . The big assortment of PV applications allows for a scope of different engineerings to be present in the market, from low-cost, lower efficiency engineerings to high-efficiency engineerings at higher cost. Conversion efficiency, defined as the ratio between the produced electrical power and the sum of incident solar energy per second, is one of the chief public presentation indexs of PV cells and faculties. PV systems can be connected to the public-service corporation grid or operated in stand-alone applications. They can besides be used in building-integrated systems ( BIPV ) 2. The investing costs of PV systems are still comparatively high, although they are diminishing quickly as a consequence of engineering betterments and economic systems of volume and graduated table. High investing costs, or entire system costs, represent the most of import barrier to PV deployment today ( Jager-Waldau, A. , 2008 ) . Associated levelised electricity coevals costs from PV systems depend to a great extent on two factors: the sum of annually sunlight irradiation ( and associated capacity factor ) , and the interest/ price reduction rate. PV systems do non hold traveling parts, so operating and care ( O & A ; M ) costs are comparatively little, estimated at around 1 % of capital investing per twelvemonth. The corresponding coevals costs for residential PV systems ranged from USD 360-720 /MWh, depending on the relevant incident solar energy. While these residential costs are really high, it should be noted that residential PV systems provide electricity at the distribution grid degree. Therefore they compete with electricity grid retail monetary values, which, in a figure of OECD states, can besides be really high ( Moehlecke, A. and Zanesco, I. , 2007 ) . Solar Water Heating Systems Solar H2O heating systems, such as the 1s pictured in China ‘s Yunnan Province, consist of a solar aggregator and a storage armored combat vehicle. The aggregator is typically a rectangular box with a transparent screen, through which pipes run, transporting H2O that is heated by the Sun. The pipes are attached to an absorber home base, which is painted black to absorb the heat. As the Sun ‘s heat warms the aggregator, the H2O is heated and passed to the storage armored combat vehicle, which shops the hot H2O heated for domestic usage. As explained by the National Renewable Energy Laboratories, â€Å" Solar H2O heating systems can be either active or inactive. Active systems rely on pumps to travel the liquid between the aggregator and the storage armored combat vehicle, while inactive systems rely on gravitation and the inclination for H2O to of course go around as it is heated ( hypertext transfer protocol: //www.geoexchange.org ) .System design and sizeSizing of resid ential solar H2O heating systems is by and large easy: the regulation of pollex is 20-gallons per individual for the first two people and 15-gallons for each extra individual in the house.The RETScreen International Clean Energy Project Analysis Software15 is an advanced and alone energy consciousness, determination support and capacity edifice tool. It consists of standardised and incorporate undertaking analysis package that can be used worldwide to measure the energy production, life-cycle costs and nursery gas emanation decreases for assorted types of proposed energy efficient and renewable energy engineerings compared to conventional energy systems ( hypertext transfer protocol: //www.homeenergysaver.lbl.gov/ ) .Market tendenciesThe planetary PV market has experienced vivacious growing for more than a decennary with an mean one-year growing rate of 40 % . The cumulative installed PV power capacity has grown from 0.1GW in 1992 to 14 GW in 2008 ( Navigant, 2009 ) . Market end-use sectors There are four end-use sectors with distinguishable markets for PV: Utility graduated table systems ( get downing at 1 MW, mounted on edifices or straight on the land ) Off-grid applications ( changing sizes ) Residential systems ( typically up to 20 kilowatts systems on single places ) Commercial systems ( typically up to 1 MW systems for commercial office edifices, schools, infirmaries, and retail ) The bulk of grid-connected systems are installed as BIPV systems. However, ground-mounted large- graduated table installings with a coevals capacity in the 10s of megawatts have gained a considerable market portion in recent old ages. As a consequence, off-grid PV systems now constitute less than 10 % of the entire PV market ; nevertheless, such applications still remain of import in distant countries and in developing states that lack electricity substructure. India India has a big and diversified PV industry dwelling of 10s to the full vertically incorporate makers doing solar cells, solar panels and complete PV systems, and around 50 assembly programs of assorted sorts. Together, these companies supply about 200 MW per twelvemonth of 30 different types of PV systems in three classs – rural, distant country and industrial. However, despite this strong industrial base, PV constitutes a little portion of India ‘s installed power coevals capacity, with 2.7 MW grid- connected systems and 1.9 MW stand-alone systems in 2008 ( Banerjee, 2008 ) . There have been a figure of high-ranking authorities enterprises that have provided new impulse for PV deployment in India, including: The 2008 Action Plan on Climate Change included a â€Å" National Solar Mission † In 2008, the Ministry of New and Renewable Energy ( MNRE ) established Generation Based Incentives ( GBI ) programme. The Eleventh Five-Year Plan ( 2007-12 ) proposed solar RD & A ; D support of INR 4 billion ( 86.4M USD ) .CO2 emanations decreaseThe deployment of PV will lend significantly to the reduced C strength of electricity coevals. Taking into history the different mean CO2 emanations of electricity production mixes in different universe parts, and utilizing the BLUE Map scenario mean long-run emanation decrease coefficients for the power sector, the 4 500 TWh generated by PV in 2050 is expected to salvage 2.3 Gt of CO2 emanations on an one-year footing worldwide, about twice that predicted in the BLUE Map scenario. This corresponds to about 5 % of the sum avoided CO2 emanations ( 48 Gt ) from all engineering countries projected in the ETP 2008 BLUE Map Scenario with regard to the Baseline Scenario. Over the period 2008-2050, the estimated cumulative nest eggs are around 100 Gt of CO2 ( Zweibel, K. , Mason, J. and Fthenakis, V. , 2008 ) . Strategic ends and mileposts Achieving the deployment way outlined in this roadmap will necessitate a important investing by authorities and industry in effectual engineering development and policy execution. This subdivision identifies short- , mid- and long-run engineering ends and mileposts and related key R & A ; D issues.Technology tendenciesAn overview of the different PV engineerings and constructs under development are summarized below. Crystalline Si Today, the huge bulk of PV faculties ( 85 % to 90 % of the planetary one-year market ) are based on wafer-based c-Si. Crystalline Si PV faculties are expected to stay a dominant PV engineering until at least 2020. This is due to their proven and dependable engineering, long life-times, and abundant primary resources. The chief challenge for c-Si faculties is to better the efficiency and effectivity of resource ingestion through stuffs decrease, improved cell constructs and mechanization of fabrication. Thin movies Thin movies are made by lodging highly thin beds of light-sensitive stuffs in the micrometre ( I?m ) scope on a low-priced backup such as glass, unstained steel or plastic. The chief advantages of thin movies are their comparatively low ingestion of natural stuffs, high mechanization and production efficiency, easiness of edifice integrating and improved visual aspect, good public presentation at high ambient temperature, and decreased sensitiveness to overheating. The current drawbacks are lower efficiency and the industry ‘s limited experience with lifetime public presentations. II-VI semiconducting material thin movies CdTe cells are a type of II-VI semiconducting material thin movie and have a comparatively simple production procedure, leting for lower production costs. CdTe engineering has achieved the highest production degree of all the thin movie engineerings. It besides has an energy payback clip of eight months, the shortest clip among all bing PV engineerings. For CIGS cells, the fiction procedure is more demanding and consequences in higher costs and efficiencies compared to CdTe cells. Today, CdTe has achieved a dominant place amongst thin movie in footings of market portion and has a market-leading cost-per W. Emerging engineerings Emerging PV engineerings comprise advanced inorganic thin movie engineerings ( e.g. Si, CIS ) every bit good as organic solar cells. Organic solar cells are potentially low cost engineerings that are about to do their market entryway for niche applications. Another emerging PV engineering is based on the construct of thermo-photovoltaics whereby a high efficiency PV cell is combined with a thermic radiation beginning. Novel PV constructs Novel PV concepts purpose at accomplishing ultra-high- efficiency solar cells by developing active beds which best lucifer the solar spectrum or which modify the entrance solar spectrum. Both attacks build on advancement in nanotechnology and nano-materials. Concentrator engineerings ( CPV ) All PV engineerings described so far are alleged flat-plate engineerings which use the of course available sunshine. As an option, direct solar radiation can be concentrated by optical agencies and used in concentrator solar cell engineerings. Water: India faces a despairing state of affairs of H2O deficit. Its fragile and finite H2O resources are consuming while the demands for H2O from assorted sectors of the economic system are quickly lifting. In recent old ages, the industrial and domestic sectors have realized this disparity in the supply and demand. The per capita handiness of H2O in India has been reduced from 5277 three-dimensional meters in 1995 to 1970 three-dimensional metres now. This is projected to cut down farther to about 1000-1700 three-dimensional metres by 2025, doing India a H2O stressed state. At the same clip, demand for H2O continues to turn and will turn 40 % from 750 bcm to 1050 bcm by 2025. Tamil Nadu receives most of its rainfall during the two monsoon seasons, viz. the South West Monsoon and the North East Monsoon seasons. The North East Monsoon brings an norm of 431.1 to 552.7 millimeter of rainfall while the south west monsoon brings an norm of 287.6 to 335.5 millimeter rainfall harmonizing to the meteoric Department records of 2008-2009. The distribution of rainfall in winter and summer is good below the 150mm grade and hence the province faces H2O deficits during most of the twelvemonth. However, if the H2O from the monsoon is expeditiously harvested, it can be channeled for usage during the rainless summers and winters so that H2O ingestion can be managed expeditiously. The tabular array below gives a image of the distribution of rainfall among the cardinal territories of the province. Rainfall is non unvarying within the province as it varies with the geographical location of the territories within the province. The hilly Nilgiris territory receives the most rainfall of over 1800 millimeter. the coastal territories stand following with rainfall ranging over 1400 millimeter in Cuddalore, Nagapattinam and Thiruvarur, and over 1200mm in Kancheepuram, Kanyakumari and Thanjavur, over 1000 millimeter in Chennai, Salem, Villupuram, Thiruvallur and Ramanathapuram. The other territories received rainfall less than or above 800 millimeters harmonizing to the existent rainfall recorded in the aforementioned territories during the twelvemonth 2008-2009 by the Meteorological Survey Department, Chennai.DISTRIBUTION OF DISTRICTS BY RANGE OF RAINFALL 2008-09Safe imbibing H2O is linked closely to the wellbeing of human life. In India, the primary beginnings of imbi bing H2O, that include surface H2O and groundwater, are contaminated by different physical drosss, agricultural and industrial wastes and belowground chemicals and minerals. The undermentioned graph gives the position of H2O supply in the territories of tamilnadu. Although most of the countries are covered with consistent warer supply, there are ruddy aeras in every territory that indicate substructure spreads or shortages in supply. As a province, Tamil Nadu is in famine of H2O and hence stringent steps are required to conserve and efficient ; y use bing resources. Archaeological grounds attests to the gaining control of rainwater as far back as 4,000 old ages ago, and the construct of rainwater harvest home in China may day of the month back 6,000 old ages. Ruins of cisterns built every bit early as 2000 B.C. for hive awaying overflow from hillsides for agricultural and domestic intents are still standing in Israel ( Gould and Nissen-Petersen, 1999 ) . Advantages and benefits of rainwater reaping are legion ( Krishna, 2003 ) . The H2O is free ; the lone cost is for aggregation and usage. The terminal usage of harvested H2O is located near to the beginning, extinguishing the demand for complex and dearly-won distribution systems. Rainwater provides a H2O beginning when groundwater is unacceptable or unavailable, or it can augment limited groundwater supplies. Rainwater is sodium-free, of import for individuals on low-sodium diets. Rainwater is superior for landscape irrigation. Rainwater reaping reduces flow to ramp H2O drains and besides reduces non-point beginning pollution.

Shower Gel Marketing

Soap, Bath and Shower Products Issues in the Market The soap, bath and shower category straddles two worlds – at once it falls into the arena of must-have consumer goods, which consumers see as integral to their everyday wellbeing, while at the same time it has an opportunity to tap into a consumer desire for escapism and fantasy. Close to half of women who use bath additives, for instance, cite a long bath as their ultimate pampering treat. How many fast-moving consumer goods segments can claim to satisfy such lofty needs with such a low ticket price?The beauty industry often cites the resilience of the colour cosmetics category in times of crisis – otherwise known as the lipstick index. It is time for the beleaguered bath additives segment to do the same and position their products as a luxury indulgence at prices accessible to most. Q: How is the economic environment impacting sales of soap, bath and shower products? A: Value sales of SBS products grew in single digi ts between 2006 and 2011 (with the exception of 2010 when year-on-year growth was more or less flat). The category is buffered somewhat from he inclement economic climate because of the must-have nature of daily cleansing products. At the same time, consumers are clearly under pressure to keep a close eye on household budgets. A third of adults who use shower products are paying more attention to how much they spend on such items because of the economic situation and the same is true for four in ten bath product users and three in ten soap users. Looking ahead, Mintel forecasts the SBS category will grow by 11% between 2011 and 2016, while in real terms (excluding inflation) sales will slip very slightly.Q: Which segments have most potential for growth? A: There is a clear divide between two promising segments – liquid soaps and shower gels – and two less buoyant ones – bar soaps and bath additives. Mintel expects liquid soap and shower gel sales to grow by 28% and 17%, respectively, between 2011 and 2016, whereas we expect bath additives to slump by 4% and bar soaps by 15% in the same timeframe. The differing performances come down to consumer preference. Adults are much more inclined to use shower gels and creams over bath additives, for instance, likely because showering is uch more convenient and is a quicker option for today’s time-poor consumer. In addition, half of soap, bath and shower product users have switched to taking showers rather than baths in an effort to save water. Meanwhile, liquid soaps have an edge over the more traditional bar format with 89% of women using liquid soaps compared to 77% who use bar soap. While they potentially offer a cost saving over liquid varieties, Brid Costello Senior UK Beauty Analyst [email  protected] com Tel: +44 (0) 20 7606 4533 A self-confessed beauty junkie, Brid tracks the UK’s fast-moving beauty market.Before joining Mintel in 2010, she spent a decade as a beauty editor f or fashion and beauty trade newspaper Women’s Wear Daily.

Soap, Bath and Shower Products Issues in the Market bar soaps suffer from a somewhat old-fashioned image. With no sign of consumers’ habits changing in the hort term, there is unlikely to be any reversal of these sectors’ performance. A third of bath and shower product users buy whatever product is on special offer, while half stock up when their favourite brands are on special offer. Q: What are consumers’ primary concerns when it comes to buying soap, bath and shower products? A: While the basic premise of SBS products is to cleanse, such items now go above and beyond that call of duty. More than three qua rters of adults who use shower products, for instance, want their gels and creams to moisturise or soften their skin, while just over half are looking or an invigorating or refreshing showering experience. When it comes to bath additives, pampering and relaxing are the key concerns for two thirds of bath product users. Women are particularly keen on luxurious soaks, with just over half considering a long bath to be their favourite pampering treat. Soap, meanwhile, has a much more pragmatic bent. Close to half of liquid and bar soap users say that cheap or good value products are their top priority, while suitability for the whole family comes second. Q: Which consumer demographics are most important to the category and how will opulation changes impact sales going forward? A: Changes in the UK’s population make-up will impact the SBS sectors to differing extents between 2011 and 2016. Shower product and liquid soap sales will likely be buoyed, for instance, given that these s ectors’ highest volume users – adults aged 25-34 – will grow in number by 872,000 in the period. Population changes are less favourable for bath additives and will do little to bolster the category, which is already in the doldrums (sales dipped by 2% in 2011). In general, however, the country’s population will increase y more than 3% (or 1. 7 million) between 2011 and 2016. Given the high penetration rates of soap and shower products, this is some good news for the category in general. Q: What influence do promotions have on the market? A: The SBS category is highly promotional with multi-purchase offers and discounts top priorities for consumers. For instance, a third of bath and shower product users buy whatever product is on special offer, while half stock up when their favourite brands are on special offer. It is little surprise then that the multiple-door grocery hains dominate the retail landscape and account for close to half of category retail sa les. With large chains – such as Sainsbury’s, Tesco, Asda and Morrisons – frequently basing advertising on their commitment to low pricing and vying with each other to offer headline-grabbing discounts, it’s unlikely the situation will change anytime soon. This will continue to put pressure on the category vis-a-vis growing value sales as consumers have become accustomed to finding their preferred goods at preferential prices.  © 2012 Mintel Group Ltd.

McDonalds marketing Case Study Example | Topics and Well Written Essays - 2500 words

McDonalds marketing - Case Study Example McDonalds's worldwide operations are characterized by ever increasing uncertainty and competition. Against this backdrop it's essential to consider the extent to which the product and service quality has an impact on customers at its restaurants. As much as fast food restaurants are highly influenced by competitor behavior as an exogenous variable, the staff also affects the consumers' perception and behavior as an endogenous variable. This paradigm of behavior is essentially associated with the ever rising fast food restaurant competition in townships across the globe and above all customer satisfaction strategies and initiatives have shaped McDonald's global operations.Thus the consumer buying behavior is influenced by various in a way that indisputably acts like the harbinger of all organizational outcomes (Fornell, & Johnson, 1996). The theoretical and conceptual framework of this research effort would be basically determined by the relevance of the existing theoretical postulate s and the conceptual frameworks of analysis and reference. Thus there will be an in-depth examination of the available literature on the subject to identify the correlations between among a set of more significant endogenous and exogenous variables involved in customer satisfaction and loyalty at McDonald's.The behavioral dimension refers to repeat purchases and attitudinal perspective refers to customers' intention to repurchase and recommend the product to others. These are good indicators of a loyal customer. Thus corporate image of McDonald's is determined by its ability to penetrate and hold niche market segments for longer duration of time. As a result the corporate image of the company receives a boost. McDonald's has been expereining a rise in its corporate image among consumers over the past few years (Gustafsson, 2005). Corporate image depends on the company's advertising, public relationship, word-of-mouth communication and actual experience related strategies and initiat ives. McDonald's has been consumer focused and is well known for its concern for customer satisfaction and service quality. Thus there is a considerable amount of positive impact on its marketing campaigns. Repeat purchases are made by customers under extreme circumstances in the fast food industry because potential customers are attracted by price discounts and unique benefits. As much as the price of the product matters product benefits also matters. Enhanced product specifications and performance act as a compulsion on potential repeat purchasers who weigh both price and quality on one hand and product innovation on the other (DiJulius, 2003). McDonald's has succeeded here. 1.1. Hypothesis or thesis statement The thesis statement of this paper rests on the testing of the primacy and the immediacy of a core group of theoretical and conceptual perspectives appertaining to the impact of product and service quality dimensions on the customer satisfaction at McDonald's against the backdrop of the former's cultural diversity and the latter's constant exposure to competition related issues along with the defined or undefined organizational outcomes (Hayes, 2008). Both a priori and a posteriori elements of customer satisfaction are inherently included in the analysis to capture the convergence/divergence framework of reference within McDonald's employee relations and work culture.

Emergence of Red Power movement in 1960s Research Paper

Emergence of Red Power movement in 1960s - Research Paper Example The period in between 1960s and 1970s, was a period that the federal government faced immense pressure from the Native Americans in regards to addressing the issues that faced the Indians at the same time the need to reassert the rights of the Indians. Emergence of Red Power movement in 1960s Outline Introduction History of Red power movement Causes for the Emergence of Red Power Movement Conclusion Bibliography Emergence of Red Power movement in 1960s Introduction Red power was a force to reckon with in the 1960s. It had a huge influence in decisions made by the government including policies. The period in between 1960s and 1970s, was a period that the federal government faced immense pressure from the Native Americans in regards to addressing the issues that faced the Indians at the same time the need to reassert the rights of the Indians. By imitating other ethnic groups at that time, the Indians in America gained courage and stood up to reaffirm their cultural and ethnic identity . It is from these ideas and operations that constituted a movement that would come to be identified as the Red Power Movement. The main and particular aim of the Red Power Movement was to do away with the federal policy of termination, lead the Indians to their ancestral and cultural ways an at the same time revitalize as well as review the existing Indian communities of that time. As the movement established itself, it emulated its counterpart movements that represented the Africa Americans and Latinos in a number of different ways. The Red Power movement used various means of operations to pass their message across the public regarding the general grievances and plight of the Native Americans they represented. Among the various means used in sending their message across are demonstrations, protests, marches and sit-ins. One of the most attention-grabbing and publicized events that was undertaken by the Red Power movement was the famous nineteen-month occupation of an abandoned fe deral prison in Alcatraz Island in early 1969. Majority of the Indian activists perceived this as the crucial spark that was part and parcel of igniting the flame of the Red Power Movement. After the occupation in Alcatraz Island, more occupations were undertaken in various locations throughout the country. The siege in 1973 that lead to the occupation of Wounded Knee, which was in South of Dakota is recoded as one of the famous sieges that overshadowed the others1. From 1971, there have been numerous protests going on throughout the country, in reserves as well as in the cities. These protests incorporated Native Americans, organizations and native newspapers, all motivated to fight for the rights and interests of the American Indians. The 1970s period is regarded as years in which there was the most intense pressure brought about by Native American protests in the whole of twentieth century. The protests that took place in early 1970s were inspired by the Alcatraz occupation model as Indians repossessed the federal land and later on reclaimed it for cultural and educational purposes2. History of Red power movement The American Indian activism roots are dated back in 1492, despite much of their activities getting recognition in 1960s and 1970s. In 1492, there was an encounter between the indigenous people of Mesoamerica and European explorers. More encounters were to occur in 1607 and in 1622. At this period, the reasons for the activism were complicated and at the same time simple. The reasons were protection of their homeland and recognition by the incoming invaders3. According to Teruton, the leaders of Red Power brought about new social knowledge that was manifested in their political operations. This knowledge was often verified with the growth of the movement. Despite the discrimination they faced from the whites and the economic and social bondage they were in, majority of the Indians soldiered on with their cultural activities. The Red Power played a great role in inspiring the American Indians in declaring their rights and culturally expressing themselves. Majority of the Indians at this moment began transforming as they compared their cultures

Finance For Managers Essay Example | Topics and Well Written Essays - 1500 words

Finance For Managers - Essay Example Top managers use budgets for the company as a whole while middle managers traditionally focus on the budget performance of their department or division. Normally the types of budgets used in different units pertain to expense budget, revenue budget, cash budget and capital budget. And expense budget focuses on anticipated and actual expense for each department. When actual expenses exceed budgeted amounts, the difference signals the need to managers to identify whether a problem exists. It could highlight inefficiencies or leakages or in retrospect if expenses are below budget, it could signal exceptional efficiency or failure to meet some other target, e.g. sales. Revenue budget lists forecasted and actual revenues of the division and / or the organization. Cash budget estimates receipts and expenditures of money of a daily or weekly basis – it shows the level of funds flowing through the organization and their nature. Cash budget is very important for liquidity management of the company for daily business activities. Capital budget is for planned investments in major assets. It not only have large impact on future expense, it is for investments designed to enhance profits of the organization. Capital budgets needs to be monitored in order to evaluate whether the assumptions made about return on such investments are holding true. Many traditional companies use top down budgeting which means that the budgeted amounts for the coming year are literally imposed on middle and lower level managers. The managers set departmental budget targets in accordance with over all company revenues and expenditures specified by top executives. Although there are some advantages to the top down process, the movement toward employee empowerment, participation and learning encourages the adoption of bottom up budgeting – a process in which lower level managers anticipate their departments’

The Question of Objectivity in Edmund Husserl Essay

The Question of Objectivity in Edmund Husserl - Essay Example Phenomenology refers to the continued endeavor to depict or illustrate experiences as well as conditions devoid of theoretical and metaphysical speculations. Husserl believed in the existence of an objective real world, which human beings have to limit, define, and bracket. According to Husserl, phenomenology refers to the science of consciousness and not of empirical things (Sawicki 2). Therefore, Husserl supported objectivity through phenomenology that aims at looking at particular examples minus theoretical assumptions before making judgments on the situation or circumstance. I agree to Husserl’s perception objectivity and that people need to make fair judgments without feelings, imaginings, and biasness on various issues pertaining to life. The reason why I support Husserl on the idea of objectivity is that it enables people become independent thinkers. When an individual is in a challenging circumstance, independent thinking might assist him make informed decisions that may relieve or save him from the situation. Being an independent thinker is beneficial to an individual since it makes him to reason out from a neutral and independent mind view (Ryan 37). The independent mind always encourages innovation and inventions since one is not confined to particular thoughts or perspectives derived from an outside source. Consequently, being an independent thinker prevents one from being brainwashed by misleading misconceptions and fallacies. This is because an independent mind usually seeks to view situations and conditions in a different perspective a nd not from experiences or assumptions of people in relation to the issue (Ryan 39). Secondly, Husserl’s position on objectivity is good since it creates a world of people with different views and thoughts, which is good for the progressive world. Since there are several challenges emerging in daily life, the need for

Marketing Article Example | Topics and Well Written Essays - 500 words

Marketing - Article Example To some, the suggestion that an orderly and analytical process of decision making, not only on a personal level – but more so in business, should include the discussion of highly controversial ethical issues, about which honest differences of opinion are common and self-deceiving rationalization endless, is repugnant. Ethics, after all, encompass wider perspectives of human concerns ultimately affecting business organizations. Ethics and social responsibility are important in the business world for a variety of reasons. Business is not all about making money. Social responsibility is considered the â€Å"obligation of an organizations management towards the welfare and interests of the society which provides it the environment and resources to survive and flourish, and which is affected by the organizations actions and policies† (Business Dictionary, 2010, par. 1). Marketers consider the type of packaging appropriate for their products that must conform to ethical standards and environmental safety concerns. Most marketers veer away from packages which are not biodegradable and which can harm the environment such as using styropore or plastics. Plastic bags have effects which are endangering the environment at an enormously fast pace, most governmental environmental agencies have recognized the immediate need to take drastic actions to stop or minimize the use of plastic bags. Firms ultimately recognize that abiding by ethical standards pay off in terms of better financial performance with employees exhibiting higher performance and productivity due to an environment of trust, employees are therefore more loyal contributing to low turnover, and a preponderance for higher investor loyalty, among others. Firms that incorporate policies on ethics and cultural diversity, social responsibilities, the concern for the environment and the community, achieve their organizational goals more efficiently with the support from their

Why do you find the Sumerian culture interesting Give at least three Essay

Why do you find the Sumerian culture interesting Give at least three reasons with specific examples - Essay Example The most interesting aspect about Sumerian culture is the profound levels of writing technique. Sumerians are credited with being the first people to demonstrate writing skills. Whereas all the others cultures adopted writing from other precedent cultures, Sumerians developed writing skills by themselves. The Sumerian writing system is argued to have come from the financial transactions between the Sumerians as a way of keeping track of financial transactions. Since there were no books to write on, Sumerians made clay tablets where they would engrave using sharp objects. Although they began engraving images of the actual objects they wanted to preserve, they soon developed a means of writing syllables. More interestingly, the writing culture later developed into a school system that has the same characteristics with the modern system of learning in that only the rich were allowed to take their children to school. Additionally, the schools were initially tailored for men (Glassner 118 -120). Sumerian culture was characterized by characteristic cities. Indeed, most of the modern cities are a reflection of Sumerian cities. Interestingly, the Sumerians made cities on raised grounds to protect the cities from floods. The cities were characterized by small sturdy houses that were clustered together. These cities share similar characteristics with modern cities, which have clustered buildings and an elaborated drainage system. What I find most interesting is the fact that the cities had slums too. Poor people lived in grass houses outside the cities (Moffett et al 42-47). Sumerians are some of the earliest farmers known to man. The most interesting thing about Sumerian farming was the tools they used for farming. Some of the hoes they used for farming were made of copper metal. They did extensive farming outside the cities but more advanced farming was done inside the cities. I find this interesting

The love for American football Essay Example for Free

The love for American football Essay Someone who is from another country like me, may believe that life in the United States is very diverse from life anywhere else. Countless people from other countries have a completely distorted image of how we may live there in America and the mentalities thatthey all posess. Not all of Americans are spoiled, overweight, or are obsessed with football. All of them are completely different for the most part, and are actually concerned about what is occurring in the world today. However, I do believe I can say that most Americans are proud to be here, and proud to represent the UNITED States, and that pride and love is shared by everyone, kind of like a big family. Just like other countries, there are things that the people tend to be attracted to more than another group of people would. For example, in Mexico, soccer is huge, and almost everyone there is crazy about it, but here in the United States, soccer doesn’t hold near as many fans. Since one doesn’t really know a lot about the life in the United States, and the things all Americans seem to enjoy, I would like to enlighten you to the one thing that I believe is totally ‘American’. And of coarse, I would have to say its football. Now, no all of Americans enjoy the hazardous sport, but about nine out of ten of them absolutely adore it(including myseld). The competition and the thrill that you get from watching breathtaking game, will most likely have you sitting at the edge of your seat, not wanting to miss a minute of whar you are seeing take place on the television screen. The runs, the cheers, the interceptions, the touchdowns, and most of all the victory when it’s all over is what I believe makes football what is it today in the society of Americans. If you were to meet another Amrican, I can almost guarantee that the person has a favorite football team that they support with all of theit hearts.

AC DC Three Phase Generators

AC DC Three Phase Generators Aims and Objectives The main objective of this report is to describe the investigation into operating characteristics of AC-DC Three-Phase generators and motors. The following subjects must be covered in this report for it to successfully document the investigation, these subjects will be constructed using a series of lab experiments and learner comments:- Operating characteristics of DC and AC generators supplying resistive, capacitive and inductive loads. Relationship between speed, current, power factor, and efficiency of a cage induction motor, capacitor start induction motor, synchronous motor and DC motor. Analyse the results from each of the experiments done and provide graphical analysis of the results. Introduction/ Background It is well known that the most regular type of power to be generated around the world is three phase AC. The reasons being are:- Three phase power is needed for the use of the most efficient types of industrial motors. It is considered to be the most efficient form of electrical energy to generate and distribute. Due to the performance of three phase, the size and weight of devices using it such as generators and motors are lower compared to devices using other power systems. Although it should be noted that the performance of an AC system is dependant on the power factor, not just the load in terms of current. In-order to successfully investigate the subject of AC vs. DC a total of six practical tests were completed, the practical tests will be documented in the following report and analysed. The tests completed:- AC induction motor torque-speed characteristics AC synchronous motor torque-speed characteristics AC capacitor start induction motor torque-speed characteristics DC motor torque-speed characteristics DC generator output characteristics AC generator output characteristics AC Induction Motor Test An induction motor is an asynchronous motor where through electromagnetic induction power is supplied to the rotating device. In some contexts an induction motor can be described as a rotating transformer because the stator can be shown to be the primary winding and the rotor as the secondary winding. Induction motors can be found regularly in industrial situations. Induction motors get their popularity from being rugged in construction, and from not having brushes. There is more than one design of induction motor a few examples are:- Squirrel Cage Rotor Motor Wound Rotor Motor Double Cage Rotor Motor Each of the above motor designs has its own merits; the type of motor to be used in this experiment is the cage rotor motor. Squirrel Cage Rotor Motor:- A cage induction motor rotor shown in the illustration below consists of a series of conducting bars laid into slots carved into the face of the rotor and shorted at either end by large shorting rings. The design is known as the cage rotor because of the conducting bars, if examined they can be seen to look like a squirrel or hamsters exercise wheel. 1Squirrel Cage Motor Construction Test The purpose of this test was to find the torque-speed characteristics of an AC induction motor. The characteristics that will be analysed against torque are:- Speed Current Output Power Power Factor Efficiency The basic idea behind the test, the motor is run at full speed and is connected to a brake unit. The brake unit can be adjusted to make the motor produce more or less amounts of torque. Starting at low motor torque, readings of current voltage and power are taken, then readings continue to be taken all they way to near stalling point. The test equipment is as follows:- Circuit Diagram for Cage Rotor Induction Motor Test:- Block Diagram To further explain and simplify, a block diagram of the test is included below. This shows exactly how the system operates. Brake Motor Three Phase Supply Torque Control Speed (rev/min) Ammeter, volt meter, watt meter Test Procedure A completely extensive test procedure can be found in the appendix taken from the Student Guide of TecQuipment Electrical Machines FH2 refer to appendix !!!.

Only one major issue occurred during the induction motor test. The fault was due to a wiring error. A link was missing on one of the watt meters which caused the motor to single phase and not rotate. It was easy to see that it was single phasing because the current measured for one of the phases was zero, indicating an open circuit somewhere. The link was quickly replaced and the test could begin. Graphical Analysis:- Now the report illustrates the results in the table T.1 in a graphical form, to make comparison the results from the test equipment manufacture have been included as a guide. Speed vs. Torque The above graph shows the relationship between speed and torque, it shows that at a low torque the speed is at its maximum but as the torque increases the adverse happens to the speed. This is expected because increasing the torque of the motor is adding more mechanical load, thus slowing the motor down. 2Manufactures graph of Speed versus Torque (Cage Induction Motor) The graph above is a representation of the results that the manufacturer of the test machines gives as a guide. It is possible to see that from a torque of 0.1Nm to 0.9Nm the results are similar to the report authors. The torque was not taken any higher than 0.9Nm in the authors test as stalling the motor was not a desired outcome. Output Power vs. Torque This graph shows the relationship of output power versus torque taken from the lab results in table T.1; it has an obvious linear upward trend. It is expected that the output power increases as more load is put on the motor, because the motor has to work harder to maintain rotation. 3Manufactures graph of Output Power versus Torque (Cage Induction Motor) The manufactures results also share the same upward trend as the authors, but again the manufacture has taken the results past 0.9Nm and taken the motor into a stalling condition. Line Current versus Torque The graph above shows the results of torque against line current, a good upward trend is visible. This indicates that as the torque increases so does the line current, this again is due to the increase in load on the motor. 4Manufactures graph of Line Current versus Torque (Cage Induction Motor) The guide results from the manufacture complement the results that the author recorded. A steady rise is shown from around 0.35-0.4A to 0.6-0.7A at about 0.9Nm. Power Factor versus Torque The graph is showing the results from the practical lab experiment, the calculated power factor versus the torque. It can be seen from the upward trend of the graph that as the torque of the motor increases, so does the power factor. It will be later seen in the report that because the power factor increases with torque so will the efficiency. 5Manufactures graph of Power Factor versus Torque (Cage Induction Motor) The guide results above show similarities with the results gained through practical lab experiments. Torque vs. Efficiency The graph is showing the relationship between efficiency and torque, the efficiency increases as the torque does, this is expected because the output power increases with the torque. The peak efficiency occurs at around 0.75-0.8Nm after which the efficiency starts to reduce. 6Manufactures graph of Efficiency versus Torque (Cage Induction Motor) The graph above shows the relationship of torque and efficiency, the manufactures results show a similar trend to that of the authors. The results from the manufactures show more of the downward trend after 0.8Nm to eventually stalling point. Conclusion Overall the results acquired through practical experiment show encouraging results, both towards theory and also towards the manufactures guide results. Some of the graphs could have been a more steady results but it is not possible to get perfect results on something like this without doing the test many more times and taking average values. The trends do illustrate what is expected, so this means the equipment was set up correctly, and the test was carried out uniformly to manufactures guidelines. The induction motor is capable of supplying torque when needed but it will not maintain a constant speed. AC Synchronous Motor Test The major characteristic of a synchronous motor is that it stays at a constant speed regardless of no load or full load. Under certain conditions they can produce a power factor that is capable of correcting a low power factor from an inductive load. A common use for a synchronous motor is to drive a DC generator. They come in all sizes from small to thousands of horsepower. The synchronous motor works by the application of three-phase AC power to the stator which causes a rotating magnetic field. The rotor sits inside this magnetic field, and is energised with a DC voltage. The rotating magnetic field of the stator attracts the rotor magnetic field caused by the DC voltage, and a strong rotating force is then imposed on the rotor shaft. This is one of the disadvantages of the synchronous motor, it needs a DC excitation voltage to start without this the rotor will not start turning. This characteristic causes the motor to have poor starting torque, most of its torque is when it is running at synchronous speed. 7Showing the parts making up a synchronous motor Test The purpose of this test was to find the torque-speed characteristics of an AC synchronous motor. The characteristics that will be analysed against torque are:- Current Output Power Power Factor Efficiency Speed has not been considered because of the way the motor operates, a constant speed should be apparent throughout the test. In the test the motor is ran at full speed, and an adjustable brake unit will control the levels of torque the motor produces. Measurements of current, voltage and power are taken at low to high torque points to get the torque characteristics of the motor.

Output Power vs. Torque The above shows the relationship between torque and output power, it can be seen that as the torque produced increases so does the output power. This outcome is expected because the motor has to turn a greater load and remain at a constant speed. 8Manufactures graph of Output Power versus Torque (Synchronous Motor) The manufactures graph also shows the output power increasing with the torque. Line Current versus Torque The line current in this graph is taking an upwards trend indicating as the torque produced is increased so does the line current. The motor is working harder to produce more torque and therefore putting more load on the line. 9Manufactures graph of Line current versus Torque (Synchronous Motor) The manufactures graph shows a smoothing increase in line current against torque but does compare with the results gained from the test. Power Factor versus Torque The power factor in this graph is shown to increase to a level above 0.8 very quickly and stays there till the end of the test (0.9Nm). Synchronous motors normally run at a very good power factor close to unity, and this is represented in the results from the test. 10Manufactures graph of Power Factor versus Torque (Synchronous Motor) The manufactures guide graph shows a similar trend to that of the report authors. Efficiency vs. Torque The above graph showing the relationship of torque and efficiency shows a really good level of efficiency produced by the motor, but the trend is not very reliable as it would not be expected to go past 1. Synchronous motors do have good efficiency higher than that of induction motors. 11Manufactures graph of Efficiency versus Torque (Synchronous Motor) The manufactures graph shows a much more reliable trend of efficiency of the synchronous motor, but it does still show that the motor is very efficient. Conclusion The results for this test could have been better and if the test was to be repeated then more effort would be made to get better measurements. Although with this in mind the graphs do show what is expected from a synchronous motor in terms of torque characteristics. In comparison to the induction motor, the synchronous motor has improved characteristics of:- Less load in terms of current on the line. Better Power factor (closer to unity) Better Efficiency It would be interesting to find out the difference in starting torque capacity of the two motors because the induction motor would be expected to have a greater starting torque than the synchronous, based on the research into the operation of these two types of motor. AC Capacitor Start Induction Motor Test The most common AC induction motor in use today is probably the single phase induction motor. The reasons for this are that they require little maintenance, and are the least expensive. In the single phase AC induction motor the stator magnetic field does not rotate, it simply alternates polarity as a result of the AC voltage changing polarity. Through magnetic induction a voltage is induced in the rotor, however this alone will not cause the motor to turn. This is why starting methods are needed for single phase AC induction motors. Capacitor Start In this type of induction motor the stator is made up of a main winding and a starting winding. The starting winding is connected in series with a capacitor, which offers between the two windings a phase difference of 90 degrees. The result when the motor is started is that between the two windings a rotating magnetic field is created and is enough to start the motor. Once nearly full speed occurs then a speed sensitive switch cuts out the starting winding and the motor runs as a single phase motor. In this way of starting the starting winding is not designed to give the motor high starting torque and so only small motors can use this system. Test The purpose of this test was to find the torque-speed characteristics of an AC induction motor. The characteristics that will be analysed against torque are:- Speed Current Output Power Power Factor Efficiency The basic idea behind the test, the motor is run at full speed and is connected to a brake unit. The brake unit can be adjusted to make the motor produce more or less amounts of torque. Starting at low motor torque, readings of current voltage and power are taken, then readings continue to be taken all they way to near stalling point.

Only one major issue occurred during the induction motor test. The fault was due to a wiring error. A link was missing on one of the watt meters which caused the motor to single phase and not rotate. It was easy to see that it was single phasing because the current measured for one of the phases was zero, indicating an open circuit somewhere. The link was quickly replaced and the test could begin. Graphical Analysis:- Now the report illustrates the results in the table T.1 in a graphical form, to make comparison the results from the test equipment manufacture have been included as a guide. Speed vs. Torque Supply Current versus Torque Power Factor versus Torque Efficiency vs. Torque Conclusion Overall the results acquired through practical experiment show encouraging results, both towards theory and also towards the manufactures guide results.

The trends do illustrate what is expected, so this means the equipment was set up correctly, and the test was carried out uniformly to manufactures guidelines. DC Motor Test The working principle behind any DC motor is the attraction and repulsion of magnets. The simplest motors use electromagnets on a shaft, with permanent magnets in the case of the motor that attract and repel the electromagnets. The reason for using electromagnets is so that it is possible to flip their magnetic field (their north and south poles). So the electromagnet is attracted to one of the permanent magnets. As soon as it reaches the permanent magnet, its north and south poles flip so that it is repelled from that magnet and attracted to the other permanent magnet.

Herbal Dietary Supplements :: Diet Supplement Weight Loss Gain Research Paper

Herbal Dietary Supplements Fit America Fit America touts itself as the very best and most practical 100% Natural system of weight loss that helps an individual lose weight without dieting. Fit America is a natural weight control that is composed of 13 herbs and minerals that supposedly "help suppress appetite, regulate the bowels and kidneys, and stimulates the metabolism so the body uses the foods consumed more efficiently." The Fit America program requires a high protein, low carbohydrate diet. Fit America promises that an individual can expect to lose up to 10 to 18 pounds per month with a proper balance of food and water consumption. These herbal supplements include astragalus, bitter orange, cascara sagrada, fo-ti, gingko, english hawthorn, henna, licorice root, ma huang, and valerian root. It is recommended that individuals who utilize the Fit America program begin by taking one gray colored herbal capsule twice a day and one peach colored herbal capsule once a day. The Fit America program then encourage s the individual to gradually increase their dosage of grey colored capsules but to take no more than eight in one day1. For a 7 - 10 day starter kit of Fit America, the price is $29.95. For a 45 day supply, the cost is $139.00. I will attempt to review the safety of these herbs and their effects on the human body. Herbal Regulations When a pharmaceutical company desires to market a prescription drug, they must meet certain procedures and standards established by the Food and Drug Administration (FDA). These procedures can last many years and incur hundreds of millions of dollars of cost for the pharmaceutical company. Before a drug can be marketed, it must first be patented and then pass three phases of clinical investigation. In Phase I, the drug is tested by giving a small amount of it to a limited number of people. At this stage, the researchers are looking for the pharmacological effects on the body such as side effects. In Phase II, individuals who have the condition that the drug is supposed to treat are tested. Approximately 100 people are tested in this phase. If Phase II shows signs of promise, then clinical investigations move into Phase III.

Statue Of Liberty :: essays research papers

I chose to write about the Statue of Liberty. The Statue of Liberty serves as a symbolic fixture of the principles America was founded on. She represents freedom, liberty, and opportunity. The location of the Statue of Liberty is an amazing feat in itself, it is right in the middle of a very wide and a very deep Hudson river, and at the time it was brought there, with the limited technology, was amazing. Adding to the location, The State of Liberty as everyone knows is right next to the old customs ports where thousands of hungry, and poor immigrants fresh off the boat would pass through looking for a better life. The fact that Liberty is a woman is an ingenious idea because a woman tends to be more sympathetic and willing to help, if Liberty was a man the statue would seem more cold, stiff, and even militant. Throughout history statues have been built to represent a great moment but the Statue of Liberty was build to symbolize a great idea and country. At that time in history people were flocking to America because they were either being persecuted in their home countries or they were just disappointed at the status of their lives and wanted to come to â€Å"the land of opportunity† to start a new life.   Ã‚  Ã‚  Ã‚  Ã‚  This is a great symbol of art because The Statue of Liberty is magnificent in every way, and serves its purpose to a superb level. Like I mentioned previously, â€Å"location, location, location .. â€Å" the statue’s location was perfect back in the days of Ellis Island and is perfect now as a tourist site. Shortly after the immigrants on the boats first spotted the land of their new homes, they came into the Hudson river to see this grand statue, and to most people it wasn’t just some lady who was standing in the middle of a river, it was the lady who was going to free them or help them from their inadequate lives.

Critical Analysis of Martin Luther King, Jr.s Speech -- Papers Have D

Critical Analysis of Martin Luther King, Jr.'s Speech Introduction In this critical analysis I am going to look at Martin Luther King, Jr and the 'I have a dream' speech. Martin Luther King, Jr is very distinguished due to the many outstanding achievements he accomplished throughout his life. He was an American clergyman and he accomplished the Nobel Prize for one of the principal leaders of the American civil rights movement. King's defiance to segregation and racial discrimination in the 1950's and 1960's helped persuade many white Americans to support the cause of civil rights in the United States. Following his assassination in 1968, King became a representation of protest in the struggle for racial justice. ====================================================================== Martin Luther King, Jr, History ------------------------------- Martin Luther King was born in Atlanta, Georgia, and he was the eldest son of Martin Luther King, Sr., who was a Baptist minister. His father enlisted as a pastor of a large Atlanta church, Ebenezer Baptists, which was founded by Martin Luther Kings, Jr's maternal grandfather. King attended a segregated school, where he excelled. He then entered Morehouse College at the age of 15 and graduated with a bachelor's degree in sociology in 1948. He went on to graduate, with honours, from Crozer Theological Seminary in 1951 and enrolled in Boston University where he achieved a doctoral degree in systematic theology, in 1955. Throughout his education, King was exposed to influences that associated Christian theology to the struggles of oppressed people. At Boston University,... ...', this is putting across the idea that God wants everyone to be, even blacks, and Gods wishes should be fulfilled. My opinion I found this speech very moving and very forceful with it meaning. It has shown me how many people had to fight to get the society we live in today and to achieve the racially equal society we live in. This speech influenced my protest and control song immensely because I used his ideas of everyone being the same underneath to write my lyrics. I tired to use similar techniques in my lyrics as King did in his speech, for example, repetition. Conclusion Martin Luther King fought hard for the world we live, which some people take for granted, although there is still some racial discrimination today I feel that his teachings will go on and live with me for the rest of my life.

Macbeth theme of kingship Essay

What is Kingship? During the Shakespearean time, being a king means that you are god-appointed to rule on Earth. It was a kings’s responsibility to rule wisely and well and his subjects’ duty to serve him loyally. We see how King Edward is described as ‘good’,’pious’,holy’ and ‘full of grace’ who has the ability to miraculously cure his subjects. While Macbeth’s tyrannical rule is contrasted to the rightful reign of good and lawful kings, bringing death and disease to his country.†i think our country sinks beneath the yoke; it weeps, it bleeds, and each day a gash is added to her wounds.† In the play Macbeth, when Duncan made his first appearance he immediately apprehends the traitors and rewards the good. â€Å"No more that Thane of Cawdor shall deceive Our bossom interest. Go pronounce his present death and with his formal title greet macbeth. He also portrays another trait of being a king, one who is humble,†there’s no art to find a mind’s construction in the face.† He expressed humility when he misjudged the previous thane of Cawdor. When Duncan rewards Macbeth with the title of Thane of Cawdor, he brought about his own downfall as a king, fulfilling the Witches prophecies on Macbeth â€Å"Hail to thee, thane of Glamis†¦ Hail to thee, Thane of Cawdor†¦ Hail to thee, that shalt be king thereafter.† When Macbeth commits regicide on the good Duncan, his inner guilt sets in and he then says,†wake Duncan with thy knocking, i would thou couldst†. After Duncan’s murder, Macbeth takes over the reign of Scotland as king. This unlawful order causes turmoil within Scotland, turning healthy Scotland to a sick and wounded Scotland under an intolerable burden.†Alas poor country, almost afraid to know itself, it cannot be called our mother, but our grave.† This shows how terrible Macbeth’s reign as a king as compared to Duncan. Macbeth does many unscrupulous deeds to keep his throne. He plots the murder of Banquo and Fleance due to Banquo suspecting Macbeth of murdering Duncan as he knew the witches prophecies. Macbeth also massacre Macduff’s family as he wants to give himself self-affirmation that he would be safe for the time being as Macbeth had been told by the witches to â€Å"beware Macduff† Finally, when Malcolm and Macduff unites to rebel against this Tyrannical Macbeth, Malcolm, the rightful heir of the throne, claims back the throne. Malcolm is seen to be the Medicine of sick scotland and macduff seen to be Scoland’s avenger. Macduff, carrying Macbeth’s head on a pole, hails Malcolm as king of Scotland and says, â€Å"Behold, where stands / The usurper’s cursed head: the  time is free† . The â€Å"time is free† because they are all now free of Macbeth’s reign of terror over Scotland. Macduff then leads the men in a shout of victory and loyalty. He says, â€Å"I see thee compass’d with thy kingdom’s pearl, / That speak my salutation in their minds; / Whose voices I desire aloud with mine: / Hail, King of Scotland!† . â€Å"Compassed† means â€Å"encircled† and Malcolm’s â€Å"kingdom’s pearl† is Malcolm’s circle of loyal thanes, who encircle him like a string of pearls encircles a crown. Macduff knows that these thanes already think of Malcolm as their king, and now he asks them to join him in shouting out loud, â€Å"Hail, King of Scotland!† And so they do, honoring Malcolm, above whose head looms th e severed head of Macbeth.
