Geothermal energy

Geothermal energy captures the heat from two to three kilometers under the earth’s surface where water meets heated rock and turns it into steam. Steam is led from boreholes to turbines inside the powerhouses of geothermal energy plants, transforming thermal energy into electricity.

Buying Energy Attribute Certificates (EACs) from geothermal energy guarantees that the renewable energy consumed is from this source.

Geothermal energy production is unique because:

  • It is a non-polluting and environmentally friendly renewable energy source
  • Has no waste and does not generate by-products
  • Has low land-use footprint
  • Does not represent a hazard for the natural surroundings
  • Has a low maintenance cost
  • Is not dependent on weather conditions.

Geothermal energy can also be used for heating and cooling, cooking, hot spring baths, agriculture, aquaculture and industrial processes.

Geothermal energy is only found in a few locations and the installation cost is high.

 

Geothermal power generation

In 2018, global geothermal power generation stood at an estimated 93 TWh, while the cumulative capacity reached 14.4 GW. Global geothermal power capacity is expected to rise to just over 17 GW by 2023, with the biggest capacity additions expected in Indonesia, Kenya, Philippines and Turkey (IEA).
