What type of power plant burns material to make electricity?

A. Geothermal

B. Radiant

C. Wind

D. Coal

Hello!

The answer is: D. Coal

Why?

Coal power plants burn coal in to get steam, the steam flows into a turbine which is coupled to an electrical generator.

Coal power plants work burning high amounts of coal into a boiler, generation a lot of steam under extreme pressures. The steam is obtained when the water is heated by the burning coal, then the steam is cooled, being transformed in liquid water again (due the condensation process) and it's sent back on a cyclical process.

Have a nice day!

Answer

Option D - Coal

Explanation

A fossil fuel power plant is a thermal power station in which fossil fuels are burned to produce electricity. Coal is a fossil fuel which is formed from the buried remains of plants and animals. Burning coal releases the energy that the plant absorbed from the sun. This energy is used to generate steam which is used to move a turbine to produce electricity. In this way, coal is burned by the power plants to produce electricity. In most of the countries, such plants provide most of the electrical energy used.
