Answer 1

Thermal Power Plant
Power stations burn a large number of fossil fuels to heat up water, to produce steam, which further runs the turbine to generate electricity. Transmission of electricity is more efficient than, transporting coal or petroleum over the same distance. It is called as the thermal plant because fuel is burnt to produce heat energy which is converted into electrical energy.

coal
Coal is the most abundant conventional source of energy which could last for at least 200 years. It is a black-brown sedimentary rock. Formation of coal occurs when the remains of plants convert into lignite and then into anthracite. This involves a long process that takes place over a long period of time. Coal helps for various proposes such as heating of the house, as fuel for boilers and steam engines and for generation of electricity by thermal plants. It constitutes about 70% of total commercial energy consumption in the country.
