How do geothermal power stations work?
Cold water is heated up and the water power turbines under the water and turns it into electricity.
The hot water from inside the earth meets cold air and produces condensation which powers the turbines 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.

dam
penstock
powerhouse
coal
What is the advantage of hydroelectric power station?
Simple in design and construction
