Energy development at US dams could power more than 4 million homes

In a study of the energy-producing potential of untapped US dams, Oak Ridge National Laboratory researchers found that 54,000 dams not currently used to generate power have the capacity to generate more than 12 gigawatts, enough to power more than 4 million homes. ORNL and Idaho National Laboratory researchers conducting a hydropower resource assessment for the Department of Energy calculated that the 100 dams with the highest energy potential could generate 8 gigawatts of power...
