Non-Conventional Sources of Energy

With increasing demand for energy, the non-conventional sources of energy, namely sun, wind, tide, biomass and energy from waste material, have gained importance in recent years.

The non-conventional sources are abundant, renewable, pollution-free and eco-friendly. Therefore, this energy has a bright future.

Serious environmental problems are caused by increasing use of fossil fuels. Hence, the need to use renewable energy sources like solar energy, wind, tide, biomass and energy from waste material, has shown its importance.

Solar Energy

India has a a lot of scope in tapping solar energy as it is located ir is a tropical country. An average of 20 MW per square kilometre per annum of solar energy can be produced in our country.

The largest power plant is the plant located at Madhapur in Bhuj area of Gujarat.

A Solar Power Plant

The use of solar energy in the rural areas will reduce the usage of firewood and dung cakes which can be used as manure in agriculture.

Wind Power

India is one of the leading producers of wind power in the world. Very large wind farms are located from Nagercoil to Madurai in TamilNadu.

A Wind Farm

There are large wind farms in Tamil Nadu, Karnataka, Gujarat, Kerala, Maharashtra and Lakshadweep.

Biogas :-

Bio gas is produced by using Shrubs, farm wastes, animal and human wastes in the rural area for domestic consumption.


A bio gas plant

Bio gas has a higher thermal efficiency when compared to Kerosene, firewood, dung cake an charcoal which are the most common sources used in the rural areas.

The material remaining after the generation of bio gas can be used as manure for cultivation. Generation of bio gas reduces the cutting of trees for firewood.

Tidal Energy :-
This is a form of that converts the energy of into electricity or other useful forms of power
Energy can be extracted from tides by creating a reservoir or basin behind a barrage and then passing tidal waters through turbines in the barrage to generate electricity.


The condition required to generate tidal power is ideal in the Gulf of Kutch. The National Hydropower Corporation has set up a tidal power plant in this region.

Geothermal Energy :-

This energy is produced by using the steam generated by the hot springs.

Hot spring

Experimental projects have been set up in India at Parvathi Valley near Manikaran in Himachal Pradesh and Puga Valley in Ladakh.
