Ventura Public Lecture - Energy From the Earth

Geo exchange systems, also known as Ground Source Heat Pumps, are an energy efficient, environmentally friendly heating and cooling technology which uses the earth beneath our feet as a heat source (in the winter) or a heat sink (in the summer). This design takes advantage of the moderate temperatures in the ground to boost efficiency and reduce the operational costs of heating and cooling systems, and may be combined with solar heating to form a geo solar system with even greater efficiency.
