In India the Ministry of New and Renewable Energy (MNRE) is the nodal Ministry of the Government of India for all matters relating to new and renewable energy. The broad aim of the Ministry is to develop and deploy new and renewable energy for supplementing the energy requirements of the country. The sudden increase in the price of oil, uncertainties associated with its supply and the adverse impact on the balance of payments position led to the establishment of the Commission for Additional Sources of Energy in the Department of Science & Technology in March 1981 – Ministry of New and Renewable Energy, Government of India. India accounts for approximately 4% of the total global electricity generation and contributes 4.43 per cent to the global renewable generation capacity amounting to 2,011 GW in 2016. The International Energy Agency's World Energy Outlook projects a growth of renewable energy supply to 4,550 GW in 2040 on a global basis. Hydro power forms the largest source of energy constituting over 43 per cent of the total renewable power generation installed capacity. A hydro power revival policy is in underway which amongst others is likely to include the classification of all hydro power projects as renewable energy.
