Which kind of power accounts for the largest share of power generation in India?

Thermal power accounts for the largest share of power generation in India, typically over 50% of total electricity production. This includes coal-based, lignite-based, gas-based, and diesel-based power plants. Coal remains the dominant fuel source within thermal power due to India's abundant domestic coal reserves. Thermal power's dominance is due to established infrastructure, lower initial costs compared to other sources, and fuel availability, though India is gradually increasing its renewable energy capacity.
