Hydropower has a dowdy, low tech image that conjures visions of concrete and degraded ecosystems. It is mostly shut out of the incentives driving solar, wind and other newer forms of renewable energy. InsideClimate News just dubbed it the “Unloved Renewable.” How wrong this image is according to a first-of-its-kind comprehensive study of the U.S. hydropower industry released by the Department of Energy’s Oak Ridge National Laboratory (ORNL) in Tennessee.
ORNL researchers found that U.S. hydropower grew by 1.5 gigawatts to 79.6 GW over the past decade, thus holding on to its seven percent share of U.S. power supply. In so doing it is offsetting roughly 200 million metric tons of carbon emissions per year, equivalent to taking more than 42 million cars off the road.
