• Geothermal energy works everywhere on Earth.

• Geothermal energy relies on the power of the sun.

• Geothermal energy makes no pollution.

Out of the choices below, which form of energy makes the most pollution?

• Geothermal

• Hydroelectric

• Fossil Fuel

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.

The following are the main components of a hydroelectric plant, EXCEPT:

• dam

• penstock

• powerhouse

• coal

This form of electrical energy generating is called
