Process+of+Geothermal+Energy

The geothermal energy process is quite straightforward. ** The Earth acts as an insulator, absorbing the energy and keeping it there. ** While the temperatures at the surface changes with the seasons, the temperatures just below the surface are relatively stable. We can exploit this temperature difference for both heating in the winter and cooling in the summer. In a residential situation, a large hole is made in the ground and filled with a series of pipes. A pump drives heat-absorbing fluid through them. Heat exchangers deliver this heat energy in the building. The process can be reversed in the summer where heat from the building can be moved and stored into the earth.
