Is clean, sustainable energy a few miles away?
Gregory Barber writes in Wired about a new “enhanced” geothermal system (EGS) built on wells drilled 7,000 feet down into completely dry, 375 degrees Fahrenheit, rock to create an artificial hot spring by pumping water into the well. The returned hot water drive turbines to create 2 to 3 megawatts of electricity. Enough to power a few thousand homes.
Pre-eighteenth-century mills were powered by wind and water wheels until the steam engine made in possible for factories to locate anywhere. EGSs show promise in creating clean, sustainable energy that may help address climate change.
