India is one of the world’s fastest growing economies. As a result, there is increasing demand for energy. India is currently the world’s fifth largest energy consumer and will move up to third place by 2030 – behind only the USA and China. Even at present rate of per capita energy consumption, which is 10 times less than developed countries, the life of our commercial energy resources such as oil, gas, uranium and coal is 25,40,80,200 years respectively. This was expressed by Prof. S.K Sharma, Professor Emeritus, Energy Research Centre, Panjab University, Chandigarh and former Member, National Security Advisory Board on the occasion of Rajiv Gandhi Akshy Ujra Diwas at Science City. The extensive use of fossil fuel based energy systems has resulted in the emission of carbon dioxide and other green house gases, which is the major cause of global warming, which has catastrophic implications for the India as well as the whole world. Studies show that the agriculture production in India will be affected and there will be draughts in some areas of the country. Government of India has already launched a national action plan on climate change under which a solar mission has been setup to produce 25000 MW of power from solar energy by 2020. Renewable energy which is decentralized in nature can help in reducing the impact of global warming . We should adopt decentralized model of power generation in contrast to western model of centralized power generation . There is a huge potential in the country to augment energy supplies by taking effective steps towards energy conservation, improving energy efficiency, substituting fossil fuels and shifting focus on renewable resources of energy at home. Energy efficiency can be improved at home, at school, at work and during recreational
