Which type of power plant uses coal as its primary fuel source?

Hydropower plant
Solar power plant
Thermal power plant
Nuclear power plant

The correct answer is: c) Thermal power plant.

A thermal power plant is a power plant in which heat energy is converted into electricity. The heat energy is produced by burning a fuel, such as coal, oil, or natural gas. The burning fuel heats water to produce steam. The steam then turns a turbine, which generates electricity.

Hydropower plants, solar power plants, and nuclear power plants are all types of renewable energy sources. Hydropower plants use the power of moving water to generate electricity. Solar power plants use the sun’s energy to generate electricity. Nuclear power plants use the heat from nuclear fission to generate electricity.

Coal is a non-renewable energy source. It is a fossil fuel that formed from the remains of ancient plants and animals that were buried and subjected to heat and pressure over millions of years. Coal is a major source of energy in the world, but it is a major contributor to air pollution and climate change.
