Geothermal Energy In some areas of the world, the extreme underground temperatures that give rise to hot springs, geysers, and other surface phenomena can be leveraged to supply electricity and heat. Here, the relatively constant temperature of subsurface environments can be exploited to meet heating and cooling needs. At the Woods Hole Research Center, the goal of energy independence is furthered by a geothermal heat pump. This system employs the Earth's thermal mass to cool office and laboratory spaces in warm weather and to heat them when it's cool outside. A growing number of homes in the region are employing geothermal heat pumps, including a home in Truro that combines geothermal and solar energy with a tight building envelope and efficient lighting, appliances, and other end uses. On an annualized basis, this is designed to be a net-zero-energy home, producing more energy than it uses. The standard basement represents the most common use of geothermal resources - it can represent an energy-efficient living space as well as a reservoir of warmer or cooler air, depending on the season.
