What is geothermal energy ? What …

Geothermal energy is the energy obtained from the earth(geo) from the hot rocks present inside the earth. It is produced due to the fission of radioactive materials in the earth’s core and some places inside the earth become very hot. These are called hot spots. They cause water deep inside the earth to form steam. As more steam is formed, it gets compressed at high pressure and comes out in the form of hot springs which produces geothermal power.

Advantages of Geothermal Energy

1) It is a renewable source of energy.

2) By far, it is non-polluting and environment friendly. 

3) There is no wastage or generation of by-products.

4) Geothermal energy can be used directly. In ancient times, people used this source of energy for heating homes, cooking, etc.

5) Maintenance cost of geothermal power plants is very less.

6) Geothermal power plants don't occupy too much space and thus help in protecting natural environment. 

7) Unlike solar energy, it is not dependent on the weather conditions.
