Climate One: Geothermal: So Hot Right Now

When most people hear the phrase renewable energy, they imagine fields full of solar panels or giant spinning wind turbines. But another source may be heating up: geothermal. Twenty years ago it was thought that geothermal could provide at most 10% of any given area’s electricity, and only in very limited regions. There were also environmental concerns about depleting groundwater. But new technological advances may have unlocked the potential for scalable geothermal energy just about anywhere. And in a bit of irony, those technological advances came from the oil and gas industry.
