Tremendous untapped potential for geothermal

A new MIT-led study on high-temperature geothermal potential in the United States concludes that there's a lot more we should be doing to tap this energy goldmine. What we're talking about here are what MIT calls "enhanced geothermal systems" that capture heat miles under the Earth's surface and turns that thermal energy into electricity. This should not be confused with low-temperature geothermal or "Earth systems" -- another large, untapped energy source -- that use ground-source heat pumps or so-called "geoexchange systems" to provide heating and air conditioning for homes and buildings.
