    en.wikipedia.org/wiki/Geothermal_heating

    Heat pipes extend the temperature range down to 5 °C (41 °F) as they extract and "amplify" the heat. Geothermal heat exceeding 150 °C (302 °F) is typically used for geothermal power generation. [6] In 2004 more than half of direct geothermal heat was used for space heating, and a third was used for spas. [1]

    en.wikipedia.org/wiki/Geothermal_energy

    Geothermal heating is the use of geothermal energy to heat buildings and water for human use. Humans have done this since the Paleolithic era. Approximately seventy countries made direct use of a total of 270 PJ of geothermal heating in 2004. As of 2007, 28 GW of geothermal heating satisfied 0.07% of global primary energy consumption. [4]
