  2. Geothermal energy - Wikipedia

    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]

    en.wikipedia.org/wiki/Geothermal_heating

    Geothermal heating is the direct use of geothermal energy for some heating applications. Humans have taken advantage of geothermal heat this way since the Paleolithic era. Approximately seventy countries made direct use of a total of 270 PJ of geothermal heating in 2004.

  4. Geothermal activity - Wikipedia

    en.wikipedia.org/wiki/Geothermal_activity

    Geothermal activity is a group of natural heat transfer processes, occurring on Earth's surface, caused by the presence of excess heat in the subsurface of the affected area, usually caused by the presence of an igneous intrusion underground. [1]

    Unlike solar and wind generation, which depend upon a shining sun or a stiff breeze, geothermal power could offer consistent 24/7 energy derived from heat that increases the deeper into the earth ...

  6. Hot spring - Wikipedia

    en.wikipedia.org/wiki/Hot_spring

    A hot spring, hydrothermal spring, or geothermal spring is a spring produced by the emergence of geothermally heated groundwater onto the surface of the Earth. The groundwater is heated either by shallow bodies of magma (molten rock) or by circulation through faults to hot rock deep in the Earth's crust .

  7. Geothermal gradient - Wikipedia

    en.wikipedia.org/wiki/Geothermal_gradient

    Heat from Earth's interior can be used as an energy source, known as geothermal energy. The geothermal gradient has been used for space heating and bathing since ancient Roman times, and more recently for generating electricity. As the human population continues to grow, so does energy use and the correlating environmental impacts that are ...

  8. Ground source heat pump - Wikipedia

    en.wikipedia.org/wiki/Ground_source_heat_pump

    A heat pump in combination with heat and cold storage. A ground source heat pump (also geothermal heat pump) is a heating/cooling system for buildings that use a type of heat pump to transfer heat to or from the ground, taking advantage of the relative constancy of temperatures of the earth through the seasons.
