Increasing demand of energy and negative impacts of fossil fuels on the environment has emphasized the need of harnessing energy from renewable sources. The world is passing through a critical period when conventional and exhaustible sources of energy are getting depleted at a very fast rate, which has focused attention to the non-exhaustible and renewable sources of energy. Renewable energy resources, which the country has in abundance, such as solar, wind, biomass, small hydro, etc. are non-depletable, and can effectively meet energy demand and are environmentally benign. They can create a significant impact in the generation of grid electricity, as progress in wind power, solar, small hydro, biomass power and bagasse co-generation has demonstrated in the last few years. About 5700 MW of power generating capacity based on renewable energy sources (RES) has been installed in the country so far. This constitutes about 5% of the total installed capacity [1].
RES (like biomass, solar, wind, etc.) that use indigenous resources have the potential to provide energy with negligible emissions of air pollutants and green house gases. Currently, RES supply 16% of the total world energy demand [2]. The political support for renewable energies has been growing continuously both at the national and international level to promote renewable energy. India's population of more than 1028 million is growing at an annual rate of 1.58%. As fossil fuel energy becomes scarcer, India will face energy shortages significantly due to increase in energy prices and energy insecurity with in the next few decades. In addition, continued reliance on fossil fuel consumption will contribute to accelerating the rates of domestic environmental quality and global warming. For these reasons the development and use of RES & Technologies are becoming vital for sustainable economic development of India.
