2. Geothermal energy - Wikipedia

   en.wikipedia.org/wiki/Geothermal_energy

   Geothermal energy is thermal energy extracted from the Earth's crust. It combines energy from the formation of the planet and from radioactive decay. Geothermal energy has been exploited as a source of heat and/or electric power for millennia. Geothermal heating, using water from hot springs, for example, has been used for bathing since ...

3. Renewable heat - Wikipedia

   en.wikipedia.org/wiki/Renewable_heat

   Hot Springs located in Nevada. Geothermal energy is accessed by drilling water or steam wells in a process similar to drilling for oil. Geothermal energy is an enormous, underused heat and power resource that is clean (emits little or no greenhouse gases), reliable (average system availability of 95%), and homegrown (making populations less dependent on oil).
