Geothermal energy refers to the energy that is stored in the form of heat below the surface of the Earth. Given that more than 98% of the Earth's volume has temperatures in excess of 1000 °C, geothermal energy has the potential to contribute significantly to satisfying global needs for heating buildings and for electricity generation. However, although its potential is high, extracting geothermal energy is considered an emerging technology, such that today the number of successfully operating geothermal systems, in particular those producing electricity, is still small.
No electricity is currently being produced from geothermal sources in Switzerland. However, wells are being drilled by the exploration industry to test if this technology can be applied locally. We are conducting supporting research into geothermal energy as a member of the Swiss Competence Center for Energy Research – Supply of Electricity (SCCER–SoE), financed by the Swiss Federal Commission for Technology and Innovation (CTI).
