The possibilities of geothermal heat
Making unused energy useable
Geothermal energy is the heat stored in the accessible part of the earth's crust. It is also called thermal energy. It can be used in various ways. For heating, cooling and also for electricity generation. The principle relies on a pipeline which is sunk into the earth and contains a salty liquid most of the time. This is heated by the thermal energy in the earth. On the surface, the heat is then transferred via a heat exchanger to the process water, which is then used for heating.
