According to the latest issue of the Federal Energy Regulatory Commission's (FERC) monthly "Energy Infrastructure Update" (with data through March 31, 2017), wind and solar provided 50.84% of the new electrical generating capacity added to the U.S. grid during the first quarter of 2017.

Thirteen "units" of wind totaling 1,479 MW combined with 62 units of solar (939 MW) exceeded the 2,235 MW provided by 21 units of natural gas and 102 MW provided by one unit of nuclear power. There was also 1-MW of capacity from "other" sources (e.g., fuel cells). In the first three months of the year, no new generating capacity was provided by coal, oil, hydropower, biomass, or geothermal.

Moreover, the pace of growth of new solar and wind capacity is accelerating. For the first quarter of 2017, new capacity from those sources is 18.07% greater than that added during the same three-month period in 2016 (2,418 MW vs. 2048 MW).

Renewable sources (i.e., biomass, geothermal, hydropower, solar, and wind) now account for almost one-fifth (19.51%) of the nation's total available installed generating capacity: hydropower (8.48%), wind (7.12%), solar (2.17%), biomass (1.41%), and geothermal (0.33%).

By comparison, at the end of 2016, renewables provided 19.17% of the total generating capacity. If current growth rates continue, renewables should top 20% before the end of this year.

Generating capacity by renewable sources is now more than double that of nuclear power (9.10%) and rapidly approaching that of coal (24.25%). **

"The Trump Administration's efforts to reboot coal and expand oil drilling continue to be proven wrong-headed in light of the latest FERC data," noted Ken Bossong, Executive Director of the SUN DAY Campaign. "Once more, renewables - led by wind and solar - have proven themselves to be the energy sources making America great again."

U.S. renewable power groups defend reliability
Washington (UPI) May 1, 2017
Industry trade groups aligned with low-carbon power sources in the United States defended their respective sectors against concerns about grid reliability. U.S. Energy Secretary Rick Perry in April called for an investigation into the resilience and reliability of the nation's energy grid. With renewable resources like solar and wind deemed variable because of the nature of their power ... read more
