Geothermal energy

Geothermal energy harnesses steam or hot water from beneath the Earth's surface. This steam or hot water can be used to power turbines to generate electricity. It can also be used directly - without conversion - to heat water or buildings.

Unfortunately, even in many countries with abundant geothermal reserves, this proven renewable energy source is being massively under used. Geothermal power generation causes virtually no pollution or greenhouse gas emissions.
