Abstract
Geothermal energy today is mainly known for its reliable production of base-load power – the power needed to meet minimum demands – in areas where geological conditions permit fluids to transfer heat from the Earth to the surface in self-flowing wells at high temperatures. However, geothermal resources at moderate temperatures can be found in aquifers that are widespread. Such resources can be used in binary power plants, combined heat and power plants or in heat-only applications. Emerging geothermal technologies that extract energy from the hot rock resources found everywhere in the world hold much promise for expanding the production of geothermal power and heat.
