Complexity – New Hope for Cleaner Energy

Is clean, sustainable energy a few miles away?

Hot rock is everywhere, with temperatures rising hundreds of degrees Fahrenheit within the first few miles of the surface, … yet geothermal plants are built where naturally heated water can be easily tapped. 

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.
