Energy is essential for all activities in and around us. It provides comfort, increases productivity and allows us to live as we want. Presently most of our energy demand is derived from conventional fossil fuels such as coal, petrol, diesel, natural gas, kerosene etc. According to an estimate oil would run out in about 40 years and natural gas soon after. Additionally, they’re degrading environment by releasing harmful byproducts and contribute to global warming and greenhouse gases. Keeping in view of the limited store of fossil fuels and ever increasing gap between the demand and supply of energy, it has become necessary to switch to new and renewable sources of energy. It is a fact India has one of the highest potentials for effective use of renewable energy. During the last one decade, there has been a visible impact of renewable energy in the Indian energy scenario. Apart from contributing to about 12.5 per cent in the national electric installed capacity, renewable energy based applications have benefitted millions of people in the Indian villages by providing for their energy needs in an environment friendly manner. India is the world’s fifth largest producer of wind power after Denmark, Germany, Spain, and the USA.
