Check out our geothermal energy facts and learn more about power from the ground.

Read about geothermal electricity production, hot springs, heating applications and other topics related to geothermal power.


  • Geothermal energy is made inside the Earth.

  • The world geothermal comes from Greek words meaning ‘Earth’ (geo) and ‘heat’ (thermos).

  • The technology behind geothermal electricity generation has improved substantially but it still only provides a fraction of world electricity generation.

  • Geothermal power is clean, reliable and cost effective but its availability is often limited to areas near tectonic plate boundaries.

  • Geothermal power plants in the Philippines and Iceland contribute around 30% of their electricity production. In the USA it is less than 1%.

  • As of 2010, 24 countries around the world use geothermal power to generate electricity while around 70 use it for various forms of heating.

  • Geothermal heating applications include industrial uses, heat pumps, space heating and bathing in hot springs.

  • Humans have enjoyed geothermal energy in the form of hot springs for thousands of years.

  • The oldest known spa fed from a hot spring is believed to be a stone pool found on Lisan Mountain in China, built in the 3rd century BC.

  • In some parts of Iceland, hot water runs from geothermal power plants under pavements and roads to help melt ice.
