Electricity produced by thermal power plants stands out to be the substantial grantor of electricity for India. Three categories of heat energy plants are present in India. These three variants have a united installed magnitude of 221,802.59 MW. This article gives a detailed account of distinct thermic energy plants present in India along with their location. Thermal power plants generate electricity by using non-renewable fuel like coal, petroleum and natural gas. The heat released by smouldering of fuel builds up steam in the broiler. The steam is then utilized to run a turbine affixed with the generator.

5. The largest source of energy in India is : [U.P. Lower Sub. (Pre) 2002, U.P.P.C.S. (Spl) (Pre) 2008]

Correct Answer: (c) Coal
Solution:

According to Power Ministry of Indian Government, India has electricity with a total installed capacity of 428299.27 MW on 31 December, 2023. India derives most of its electricity from fossil fuels; primarily from coal (India has 240022.92 MW based on thermal energy capacity on coal which is 56.04% of total capacity. India also derives a considerable amount of electricity from hydropower sources. Currently, 46910.17 MW of installed capacity on hydroelectricity, 133886.18 MW of installed capacity on Renewable Energy Sources (RES) and 7480 MW of installed capacity on nuclear sources.

6. The highest share in power generation in India is of: [U.P.P.C.S. (Mains) 2011, U.P.P.C.S. (Mains) 2006]

Correct Answer: (d) All above have equal shares
