India's maximum energy comes from:

The bulk of India's energy comes from thermal power plants, which burn coal and other fossil fuels to generate electricity.

Hydroelectric plants supply clean power but form a much smaller portion of the total.

Nuclear plants add only a minor slice, close to three percent, of national generation.

Solar plants are expanding quickly yet still trail well behind the thermal share.

India's abundant coal reserves make coal fired generation the cheapest and dominant choice.

This reliance on coal also makes the power sector a leading source of the country's carbon emissions.
