Geothermal energy (earth heat) is the naturally occurring heat energy that is below the Earth’s surface. The name ‘geothermal’ comes from Greek roots: {geo} γη (ge) – meaning earth, and {thermal} θερμος (thermos), meaning {heat} hot.
Electricity is generated by geothermal power stations using geothermal energy resources. Geothermal power stations are power stations that generate electricity using the two main types of geothermal resources – that is, heat energy is extracted from underground in the form of hot steam and water or hot rocks, also known as magma.
Based on the two main types of geothermal energy resources, there are two types of geothermal systems:
