Which is the most important source of energy in India?

Coal contributes to 55.88% of the total energy produced in the country making it the largest source of electricity generation and the most important source of energy.

What is the importance of coal as a source of energy and as a source of raw material?

Coal is primarily used as fuel to generate electric power in the United States. In coal-fired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into high-pressure steam, which drives a turbine, which produces electricity.
