Study: Power from U.S. renewables almost quadrupled over decade

Washington Post ($):

The proportion of electricity the United States gets from solar and wind nearly quadrupled between 2011 and 2020. While geothermal generation remained relatively flat, the three technologies combined for an annual increase of nearly 15 percent over that stretch.

Those findings come from a report released Tuesday by the nonprofit Environment America Research and Policy Center and the nonpartisan research organization Frontier Group. The analysis also found that if the current growth rate continues, wind, solar and geothermal would meet current electricity demand levels by 2035 — which is when President Biden aims to have an entirely fossil-fuel-free grid.

“The pace of progress is continuing to pick up,” said Emma Searson, an author of the new report. “That’s exactly what we need to see in years to come.”

Using U.S. Energy Information Administration data, Searson and her colleagues calculated that the United States went from producing 125,820 gigawatt-hours of wind and solar electricity in 2011 to 470,141 gigawatt-hours in 2020. Geothermal generation stayed largely constant and, as of 2020, stood at a relatively low 16,930 GWh.

Solar generation grew particularly quickly, with the report finding a 23-fold increase since 2011. Wind, which started at a higher percentage than solar, saw an almost threefold increase. Three states — Iowa, North Dakota and Kansas — now produce at least half the amount of electricity they consume from wind and solar.
