SUN DAY Campaign: First Third 2020

U.S. Renewables Produced 27.1% More Electricity Than Coal – and Also Outpaced Nuclear Power

Solar + Wind Now Provide One-Eight Of U.S. Electricity

Non-Hydro Renewables Grew 3.7% In April Notwithstanding Covid-19

Washington DC – Renewable energy sources (i.e., biomass, geothermal, hydropower, solar, wind) produced significantly more electricity than coal during the first four months of 2020 and topped nuclear power as well, according to a SUN DAY Campaign analysis of just-released data from the U.S. Energy Information Administration (EIA).

The latest issue of EIA’s “Electric Power Monthly” (with data through April 30, 2020) reveals that solar and wind both showed continued, strong growth, expanding faster than all other energy sources. During the first third of this year, solar-generated electricity – including distributed solar – expanded by 20.7% (compared to the same period in 2019) and provided almost 3.0% of the nation’s total. Wind grew by 12.2% and accounted for more than 9.3% of total generation.

Thus, wind and solar together provided 12.3% – or nearly one-eighth – of total U.S. electrical production during the first four months of 2020. Combined with hydropower, biomass, and geothermal, renewables provided 21.6% of total electrical output.

Moreover, renewables produced 27.1% more electricity than coal during the first third of 2020. Electrical generation by coal was 33.5% lower than a year earlier and accounted for just 17.0% of the nation’s total.

In addition, renewable energy sources produced 2.5% more electricity than did nuclear power during the same period. In April alone, renewables outperformed nuclear power by 14.9%.

EIA’s data for just the month of April also provide the first indication of the possible impacts of the coronavirus on competing renewable energy sources.

While hydropower’s output fell by 18.5%, non-hydro renewables provided 3.7% more electricity in April than a year earlier – driven primarily by 17.1% more generation by solar. Geothermal and biomass also increased by 9.5% and 0.7% respectively while wind dipped by 0.6%.

NOTE: The figures cited above include EIA’s “estimated small-scale solar photovoltaic” (e.g., rooftop solar systems) which account for about a third of total solar output.

The latest issue of EIA’s “Electric Power Monthly” was officially posted late on June 24, 2020.
