The Earth is a giant solar collector that absorbs Solar Energy from the sun and stores it as Geothermal Energy. At depths of 30+ feet here in NJ, New Jersey this Geothermal heat energy is a constant 50+ degrees. We use this stored energy by drilling Geoexchange energy wells (we are also NJ licensed master well drillers) and installing a Geothermal heat pump to use this free solar powered Geothermal heating cooling energy.
