Deep geothermics
Deep geothermics is the term used to describe utilisation of geothermal energy at depths between 400 and 5,000 metres. The temperatures there are far higher than those used as near-surface geothermal energy. Apart from heat supply, deep geothermal energy can be used for electricity generation. Economic electricity generation is possible from a temperature of around 90 degrees Celsius. The advantage of geothermal energy is its constant availability. Geothermal power production is still in the initial stages in Germany. Three plants are in operation to date, one in Neustadt-Glewe, one in Landau and one in Unterhaching.
