Describe Any Three Non-Conventional Sources of Energy.

Non-conventional sources of energy are:

Solar Energy: India is a tropical country. It has enormous possibilities of trapping solar energy. Photovoltaic technology converts sunlight directly into electricity. Solar energy is rapidly becoming popular in rural and remote areas.

Wind Energy: India now ranks as a ‘wind super power’ in the world. The largest wind farm cluster is located in Tamil Nadu from Nagercoil to Madurai. Apart from these, Andhra Pradesh, Karnataka, Gujarat, Kerala, Maharashtra and Lakshadweep have important wind farms. Nagercoil and Jaisalmer are well-known for effective use of wind energy in the country.

Biogas: Shrubs, farm waste, animal and human waste are used to produce biogas for domestic consumption in rural areas. Biogas plants using cattle dung are known as ‘Gobar Gas Plants’ in rural India. These provide twin benefits to the farmer in the form of energy and improved quality of manure.
