As of recent data, thermal power, primarily generated from coal, remains the single largest source of energy production and electricity generation in India. Although India has significant potential in renewable energy sources like solar and hydro, and is expanding them rapidly, thermal power plants currently contribute the largest share to meet the country's energy demands. Hydel power (A) and Solar power (B) are significant but individually contribute less than thermal power overall. Nuclear power (C) accounts for a relatively small percentage of the total energy mix.
