Geothermal energy is heat energy generated and stored in the Earth.
Geothermal energy is generated at the geothermal power plants where the heat of earth is used to generate electricity.
Due to some geological changes, the molten rocks present in the core of the earth are pushed to the earth’s crust. Steam is generated when the underground water comes in contact with these points forming hot springs. This trapped steam is used to generate electricity in the geothermal power plants.
