Part 1 of Geothermal Energy: Power from the Depths of the Earth. The Earth’s crust is a bountiful source of energy—and fossil fuels are only part of the story. Heat or thermal energy is by far the more abundant resource. To put it in perspective, the thermal energy in the uppermost six miles of the […]
Part 2 of Geothermal Heat Pumps. Geothermal heat pumps can reduce energy consumption—and corresponding air pollution emissions—up to 44% compared to air source heat pumps and up to 72% compared to electric resistance heating with standard air-conditioning equipment. (Source: EPA, 1993) Geothermal heat pumps are viable nationwide. They use the Earth as a heat sink […]
Part 1 of Geothermal Heat Pumps. If you’re planning to build a new house, office building, or school, or replace your heating and cooling system, you may want to consider a geothermal heat pump (GHP) system. GHP systems are also known as GeoExchange, ground-source, or water-source heat pumps (as opposed to air-source heat pumps). Regardless […]
