Shallow geothermal energy

Shallow geothermal energy

Shallow geothermal energy is based on the same fundamental principle as solar thermal energy. However, in this case it is the ground which is acting as a heat source, not the sun. There is an underground pipe system in which a liquid heat transfer medium circulates.
