Every single U.S. electrical power plant that came online in July was a renewable energy plant, according to the federal agency that regulates the nation’s power grids. The July “Energy Infrastructure Update” published this week by the Federal Energy Regulatory Commission (FERC), reports that all of the 405 megawatts’ worth of new electrical generating capacity going into service in that month derives its power from wind, sun, or water.
Between July 1 and 31, 379 megawatts of wind power generating capacity went online, along with 21 megawatts of solar and five megawatts of hydroelectric capacity, that last from a small dam outside Ketchikan, Alaska.
In that same time period, not a single fossil-fueled power plant went online: no coal, oil, or natural gas.
