Geothermal energy uses heat from under the earth’s surface either for heating or for producing electricity. When the underground temperature is hot enough (like in Iceland), electricity can be produced directly from the steam or hot water found beneath the surface.
It’s an emerging form of electricity generation but one which has a lot of potential – it’s reliable and doesn’t cause emissions or pollution. Even better, you don’t need to worry about rising fuel costs because the energy is free. This is good news given Iceland’s precarious financial situation.
