Geothermal energy is considered a renewable resource. Ground source heat pumps and direct use geothermal technologies serve heating and cooling applications, this design takes advantage of the moderate temperatures in the ground to boost efficiency and reduce the operational costs of heating and cooling systems.
Geothermal systems are becoming increasingly popular during the surge of green building and ground source heat pumps are among the most energy efficient technologies for providing water heating, ventilation, and air conditioning.
