What are the three basic sources of generating power?

The three basic sources of generating power are thermal, hydro electricity and nuclear power
(ii) The thermal power uses heat energy as its base for the production of electricity.
(iii) Hydroelectric power involves production of electricity through the use of kinetic force of falling water
(iv) Nuclear power involves the use of sustained
nuclear fission to generate electricity. The thermal sources, hydro electric sources and nuclear power accounts for 70%, 28% and 2% of the power generation capacity respectively in India.
