Which sector contributes the maximum to India's total electricity production?

Thermal power, chiefly coal based, supplies the largest share of India's electricity generation.

Nuclear power contributes only a small fraction, close to three percent of the total.

Renewable sources such as solar and wind are growing fast but still generate less than the thermal fleet.

Hydropower is a significant clean source yet remains well below thermal output.

Coal fired stations dominate because of large domestic coal reserves and established plants.

This heavy coal dependence is why India is pushing a rapid expansion of renewable capacity.
