It makes up less than 1% of the world's primary energy supply. Since not all countries can feasibly extract this energy, geothermal energy is not in prominent use globally. This makes it fairly reliable, and allows its use as a baseload power provider to the electrical grid. Ī benefit of geothermal energy is that it is not intermittent like solar and wind power, which means it can be used at any time of the day, any day of the year. Countries around the world are currently limited by technology when it comes to harnessing geothermal energy, and only those lying on certain "geothermal hot spots" (Figure 2) may tap into this energy effectively. Geothermal energy is extracted in the form of steam or hot water from the subsurface, which can then be used for many purposes (see geothermal electricity and heating). Deep underground, the Earth will remain hot for billions of years, so geothermal energy can be used for a long time (as a renewable energy source), but if the resource is not treated carefully, it will not be sustainable. It can be used directly for heat or to create electricity. Geothermal energy is a form of primary energy. Geothermal energy is energy that is extracted from thermal sources that originate deep underground.
