Sustainable Energy 2Executive SummaryIndia is committed to achieving the goals of sustainable energy as agreed by the international forums. Concentrating Solar Power technology is based on focused sunlight in which power is generated by CSP plants by using mirrors that concentrate or focus the energy from the sun and change it into a heat of very high temperature. CSP is one of the most promising in India for the days to come following the upsurge in the amount of electricity produced by concentrated solar power in India every year. India has huge potential for solar power for the generation of solar electricity per watt that is built following its geographical and climatic characteristics. Only 52.5 MW of the 470 MW CSP plants are operational in India showing a chunk of the task that needs to be done. Various challenges and hurdles are attributed to this poor score.

Sustainable Energy 4CONCENTRATING SOLAR POWER IN INDIAIntroductionThe sun in conjunction with its excess solar energy is used in meeting numerous diverse functions in the daily lives of human beings across the world. Be it air circulation, supporting thegrowth of plants or heating of water, the sun and its solar energy of utmost importance. A study conducted on the technologies and uses of solar energy established that the most common and prevalent applications of the solar energy are a generation of electricity and heating. Just like coal, natural gas and petroleum, the sun is cheap and readily a viable source of energy with an exceptional feature of being renewable and clean. Thin film, photo-voltaic, CPV are some of the technologies in solar energy render solar power in India least prominent but a very important contributor of power generation[CITATION GSr14 \p 320 \l 1033 ].India, just like any other countries in the world is struggling to meet the sustainable developmentgoals despite the numerous challenges and obstacles that it finds on its ways to the achievement of such goals[CITATION PTh14 \p 265 \l 1033 ]. From the abundant reserves of fossils fuels available in the country, achievement of the sustainable energy foals that have been set out by national and international agencies remains a major challenge that calls for diverse ranges of options. To lower its dependence on imported coal as the greatest chunk of India’s primary energy is from coal, the country is making remarkable progress when it comes to introducing renewable energy power techniques and facilities. The current state of CSP technology in IndiaVarious issues among them environmental concerns, scarcity of fuel and availability of site are the challenges and hurdles that conventional power plants suffer. These problems are overcome
Sustainable Energy 5using alternate technologies which borrow from renewable energy sources such as biomass, windand solar. From the numerous options available in solar technology, generation of power throughConcentrating Solar Power, CSP, is one of the most promising in India for the days to come[CITATION Man16 \p 269 \l 1033 ]. There has been an upsurge in the amount of electricity produced by concentrated solar power in India every year. This illustrates the commitment of thecountry towards attaining sustainable, reliable and affordable energy for its citizens. India has huge potential for solar power for the generation of solar electricity per watt that is built. This is attributed to its solar radiation that ranges between 1700 and 1900kW per kilowatt peak. The potential is also attributed to the numerous clear sky days in the year which is about 300 days. India has more than enough land that can be used in the implementation of concentrating solar power technologies[CITATION Céd111 \p 237 \l 1033 ]. The land areas are not only in abundance but also ideal for direct normal radiation levels which are important in making Concentrating Solar Power an integral contributor to the energy mix of India. In its efforts to realizing Concentrating Solar Power, India introduced a ley of Rs 50 per ton of coal that was either produced domestically or imported. The levy was to be used in funding a National Clean Energy Fund of which Concentrating Solar Power is among them. Concentrating Solar PowerConcentrating Solar Power revolves around accumulating heat from the rays of the sun to a specific point on a surface for heating oil, water or any other material that is intended to be heated. Concentrating Solar Power works by concentrating and focusing the sun rays on a very small area which would otherwise be spread over a large area. This small area can be composed of water that is flowing through some pipe or any other fluid is it liquid or gas containers. Due toits ability to retain heat efficiently and for a long time, molten salt is often considered as the best

This heat can then be used in the generation of electricity[CITATION Him17 \p 170 \l 1033 ]. Concentrating Solar Power technology is based on focused sunlight. Power is generated by CSP plants by using mirrors that concentrate or focus the energy from the sun and change it into a heat of very high temperature. The heat is then passed through a conventional generator. CSP plants have two parts: the part responsible for collecting solar energy and changing it to heat and the other part that changes the heat energy to electricity. Any of the CSP technologies approaches need very large areas for collection of the solar radiation when production of electricity is to be done on a commercial scale.The technology of conversion of heat to power is normally applied in power plants that produce electricity through steam turbines. In these plants, water heated by the heat from solar energy is changed into steam which is then used in operating a turbine that in turn produces electricity. In larger power plants, the supply of the heat is supplemented by burning of coal as coal has a high capability of generating large amounts of heat. Concentrating Solar Power is used instead of coalso as to lower the harmful impacts of using coal among them air, water and land pollution[CITATION Pat152 \p 312 \l 1033 ]. A mirror used in reflecting light to the point of focus is the main component of Concentrating Solar Power. India has three main technologies used for Concentrating Solar Power based on the types of mirrors that have been in the system. The types of technologies include parabolic troughsystem power tower system and dish Stirling system.
