Abstract
Geothermal energy takes a rather subordinate position among renewable energy sources. There are two possible sources for it: the radioactive decay of natural radio nuclides which causes the spread of heat onto the earth's surface, and the storage of solar energy in the top layers of the earth. For this reason, geothermal energy is available in many places and independent of the different seasons of the year. The installation in the town of Prenzlau - which was built when this was still the German Democratic Republic, and was re-activated in 1995 - was the first one in the world to extract heat from the Earth's interior by means of a 2.9 km deep drilling hole, without mass transfer.
