Geothermal energy uses ground source heat pumps connected to buried loops underground to extract heat from the earth and transfer it to buildings for heating and cooling, providing an environmentally friendly renewable energy source. The system works through a heat pump connected to buried piping that circulates a fluid to absorb heat from or release heat to the ground depending on the season, with distribution systems transferring the heated or cooled air throughout buildings.
