Geothermal power is power extracted from heat stored in the Earth’s core.
We can recover this heat as steam or hot water and use it to heat buildings or generate electricity..
Geothermal energy is generated in the Earth’s core. Temperatures hotter than the sun’s surface are continuously produced inside the Earth by the slow decay of radioactive particles, a process that happens in all rocks.
Geothermal energy is a renewable energy source because the heat is continuously produced inside the Earth.
Geothermal power is cost effective, reliable, sustainable, and environmentally friendly, but has historically been limited to areas near tectonic plate boundaries. Recent technological advances have dramatically expanded the range and size of viable resources, especially for applications such as home heating, opening a potential for widespread exploitation. Geothermal wells release greenhouse gases trapped deep within the earth, but these emissions are much lower per energy unit than those of fossil fuels. As a result, geothermal power has the potential to help mitigate global warming if widely deployed in place of fossil fuels.
