India is blessed with an abundance of non-Conventional Sources of Energy like sunlight, water, wind and biomass. The growing need of energy has resulted in the country made dependent on fossil fuels such as coal, oil and gas. These are called non-conventional energy sources. It has the largest program for the development of these renewable energy resources.

There is a capacity of about 1, 95,000 MW non-conventional energy in India. 31 % of it is the form of solar energy, 30% in ocean and geo-thermal, 26 % in biomass and 10 % in wind energy.

1. Solar Energy - India is a tropical country. It has enormous possibilities of tapping solar energy. The largest solar plant of India is located at Madhapur, near Bhuj, where solar energy is used to sterilize milk cans.
2. Wind power - India now ranks as a “wind super power” in the world. The largest wind farm cluster is located in Tamil Nadu from Nagarcoil to Madurai.. Apart from these, Andhra Pradesh, Karnataka, Gujarat, Kerala, Maharashtra and Lakshadweep have important wind farms. Nagarcoil and Jaisalmer are well known for effective use of wind energy in the country.
3. Biogas - Decomposition of organic matter yields gas, which has higher thermal efficiency in comparison to kerosene, dung cake and charcoal. Biogas plants are set up at municipal, cooperative and individual levels.
4. Tidal Energy - Oceanic tides can be used to generate electricity. Floodgate dams are built across inlets. This includes about 7,000 MW in the Gulf of Cambay in Gujarat, 1,200 MW in the Gulf of Kutch and 100 MW in the Gangetic delta in the Sunderbans region of West Bengal.
