PoA Briefing Paper: Geothermal Energy
Geothermal energy, which literally translates to ‘earth’s heat energy’ is the latest entry into the basket of renewable energy sources that has an important role in the transition to a 100% renewable energy future. Geothermal energy is a renewable resource because it exploits the earth’s high and low temperature heat found in deeper or volcanic hot geological rocks, and in the sub-surface with widely spread ambient heat which is abundant. The hot groundwater or steam used to transfer this subterranean heat to the point-of-use can be reused, without significant loss. Geothermal energy can be harnessed for energy applications either through the generation of electricity or through the direct-use applications such as industrial heat requirements and space heating.
