What is geothermal energy?
The heat energy of the Earth is used to generate electricity by geothermal plants . This heat energy of the Earth is known as geothermal energy.When there are geological changes, the molten rocks present in the core of the earth are pushed to the earth’s crust. This forms regions of hot spots. Steam is generated when the underground water comes in contact with these hot spots forming hot springs. This trapped steam is used to generate electricity in the geothermal power plants.
