It can be useful in producing electricity and cooling and heating purposes. Geothermal energy is obtained due to the slow decay of radioactive elements in the Earth's core.
Advantages of geothermal energy:
(1) Environment friendly
(2) Renewable energy source
(3) Sustainable energy source having high potential
