How Geothermal Energy Works Part II

In this part of How Geothermal Energy Works, we will review how geothermal energy is converted into useable energy through geothermal heat pumps. A geothermal heat pump (GSHP) or ground-source heat pump[1] is a heating and cooling system that uses the ground as source of heat during the winter and a sink for heat during the summer. Invented by Lord Kelvin in 1852, the heat pump was developed by Peter Ritter von Rittinger in 1855 and built in the late {Read More}

100 Geothermal Energy Facts

The word geothermal is a fusion of “geo”,  a Greek word meaning “Earth,” and “therme” a Greek word meaning “heat. Geothermal power originates from the Earth’s formation, decay of radioactive isotopes, volcanic activity and solar energy. The temperature increases around 80 degrees Fahrenheit for each mile of depth below the Earth’s surface. At the center of Earth is a solid core with an estimated temperature of about 8,000 °F (4426 °C). The high temperature of the Earth’s core melts the {Read More}
