Damming a river can be environmentally damaging but the flow of water on our water-rich continent is also a significant source of power that would reduce greenhouse gases. New approaches to harnessing water power are being developed.Pop Sci.com reports:
"Installed this winter in –30° weather and switched on in January, the Houston-based Hydro Green Energy's pilot plant is the first federally licensed hydrokinetic project in the U.S. Like an underwater wind turbine, it will produce electricity by using the high-velocity current gushing out of an existing hydroelectric dam to turn a 12-foot, three-blade fan. Known as "run-of-river" hydrokinetic, Hydro Green's technology is similar to turbines that are being used to tap tidal power in Europe, except it's optimized to work in water flowing in just one direction (tidal turbines use water flowing both in and out)."
