Geothermal energy is the heat energy in the Earth’s interiors.
Geothermal power supplies less than 1% of the world's energy.
It is a renewable energy source because the water is replenished by rainfall and the heat is continuously produced inside the earth.
It is generated in the earth 's core, about 4,000 miles below the surface.
Disadvantage:The sites from where geothermal energy comes out hot springs , hazardous gases or minerals may also come out with steam from the earth crust. Producing electricity through geothermal energy is a safe process but digging it out from the underground can be harmful for us.
Advantage:Electricity can be produced,It is renewable.
