Question

What is geo thermal energy? Explain in brief.

Answer 1

Geo thermal energy: The heat energy possessed by the rocks inside the Earth is called geothermal energy.
The hot rocks present at the hot spots deep inside the Earth, heat the underground water and turn it into steam. This steam is compressed at high pressure between the rocks. Holes are drilled deep into the Earth up to the hot spots to extract the steam through pipes, which is utilized to rotate the turbines connected to the armature of an electric generator to produce electricity.
