How hot does it have to be to be a good place for a geothermal plant?

    300°F to 700°F

    The surface temperature can be anything from Arizona desert heat to Iceland’s brrr tundra cold. What counts is the temperature underground. There are geothermal reservoirs in the “Ring of Fire” that runs along the coasts of the Pacific ocean. Places where there are surface signs like hot springs, geysers, and volcanoes. Most of the geothermal resources that are close enough to the surface to get at are near tectonic plate boundaries. This puts most of the geothermal in the US in the SouthWest.

    The Earth’s core is waaaay hot enough, but hard for us to reach. So, we use these portals of hydrothermal resources.
