Geothermal Energy: Massive Potential, Earthquake Risk | IdeaFeed | Big Think | geothermal energy |

New research has doubled the number of sources available for geothermal energy extraction within the United States. The study comes from Southern Methodist University—sponsored by Google's philanthropic arm—and sets a new depth standard of 6.5 kilometers and takes a survey of the entire country, while past attempts have concentrated only on the western states. With 35,000 sites available, the energy take could be three million megawatts, enough to power the nation three times over.
