Geothermal Energy and Climate

The origin of the Earth's geothermal is mainly due to the heat from:

• the original Earth's formation

• the decay of radioactive element

• the radiation from the sun

• the explosion in the core of the Earth

Where is Geothermal energy most used?

• Iceland

• Greenland

• Sweden

• Denmark

How do geothermal power stations work

• Cold water is heated up and the water power turbines under the water and turns it into electricity!

• Cold water is pumped down and the cold water meets the hot water from inside the earth to produce steam to power turbines then creating electricity !

• The hot water from inside the earth meets cold air and produces condensation which powers the turbines and turns it into electricity!
