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!
