Data Shows Renewables Provide More Electricity Than Nuclear and Coal Plants

Citing concerns about national security and grid reliability, the Trump Administration is weighing options for subsidizing and preventing the closure of environmentally polluting nuclear and coal plants made uneconomic by growing competition from renewable energy and natural gas. However, an analysis by the SUN DAY Campaign of recent data from the U.S. Energy Information Administration (EIA) and the Federal Energy Regulatory Commission (FERC) suggests that such concerns are not only unfounded but the trend is also potentially too late to reverse.

A review of 2017 state-by-state data presented in EIA’s “Electric Power Monthly” report reveals that renewable energy sources (biomass, geothermal, hydropower, solar, wind) are now providing more electricity than nuclear power in over half the states and more electricity than coal in a third. And the numbers continue to shift in favor of renewable sources, particularly as falling renewable energy prices and declining electricity demand make nuclear and coal ever-more uneconomic.

Nationwide, according to FERC’s “Energy Infrastructure Update,” renewable sources now account for 20.66 percent of the total available installed generating capacity. That is more than double the generating capacity of the nation’s nuclear plants (9.12 percent) and is approaching the capacity of the nation’s coal plants (23.04 percent), which has dropped from 28.9 percent just five years ago.

Moreover, FERC reports that proposed generation additions and retirements over the next three years could result in a net loss of an additional 15,898-MW of coal capacity and an increase of just 756-MW of nuclear capacity while utility-scale renewable sources are projected to mushroom with 156,981-MW of new capacity, primarily from wind (90,981-MW) and solar (52,216-MW). And the potential growth in solar does not include distributed, small-scale PV systems (rooftop solar) which could account for an additional 30 percent or more in solar capacity.

Renewable energy critics note that generating capacity is not the same as actual electrical generation because nuclear and coal typically have higher capacity factors than most renewable sources. True enough, but …

In terms of actual generation, renewables are now neck-and-neck with nuclear power, and may hold a small lead. The most recent EIA data show renewables (including distributed solar) providing 20.17 percent of the nation’s electrical generation during the first five months of 2018 compared to 20.14 percent from nuclear power. In fact, during the two most recent months reflected in EIA’s data (April & May 2018), renewables provided 10.6 percent more electricity than did nuclear power. Renewables also outpaced nuclear power twice last year, in March and April 2017.

While coal still provides a greater share of U.S. electrical generation (26.6 percent for the first five months of 2018) than renewables, it is in a tailspin; dropping from 39 percent five years ago, while renewables have grown from a 14.3 percent share over the same period.

These trends are likewise playing themselves out on the state level.

End-of-the-year data issued by EIA for calendar year 2017 reveal that nuclear power is now providing no electrical generation in 20 states plus Washington, D.C. Of these, four states have gone nuclear-free in recent years (Colo., Maine, Ore., Vt.). Consequently, renewables are now providing more electricity than nuclear power in 27 states, plus Washington D.C.; solar (utility-scale + distributed) alone is outpacing nuclear in 21 states while wind alone already exceeds nuclear in 22 states and is closing the gap in others. Even in six states still using nuclear power (Calif., Iowa, Kan., Minn., Texas, Wash.), renewable sources are providing more electricity.

In addition, utility-scale renewable energy sources are out-producing electrical generation by coal in 17 states (plus Washington, D.C.). Further, EIA reports no electrical generation from coal in 2017 in two states (Rhode Island and Vermont) as well as Washington, D.C.

“EIA and FERC data underscore that the renewable energy train has left the station,” notes Ken Bossong, executive director of the SUN DAY Campaign. “Trying to reverse that situation with costly subsidies for environmentally-polluting nuclear power and coal defies common sense.”

“Nuclear and coal can’t compete with renewable energy,” says Tim Judson, executive director of the Nuclear Information and Resource Service. “Renewables will be generating more power than nuclear by 2020, and nuclear is poised for the same decline as coal in the coming years.”

Alaska, Calif., Colo., Del., Hawaii, Idaho, Ind., Ky., Maine, Mont., N.D., N.M., Nev., Okla., Ore., R.I., S.D., Utah, Vt., W.Va., Wyo., + D.C.

Utility-Scale Wind-Generated Electricity Exceeds Nuclear Power in 22 states:
Alaska, Colo., Del., Hawaii, Iowa, Idaho, Ind., Kan., Maine, Mont., N.D., N.M., Nev., Okla., Ore., R.I., S.D., Texas, Utah, Vt., W.Va., Wyo. (In addition, wind-generated electricity is close to that from nuclear power in Washington state; the gap is also small in Nebraska.)

Utility-Scale Wind + Utility-Scale & Distributed Solar Combined Exceed Nuclear Power in 24 states + D.C.:

(In addition, the numbers are very close in Minnesota; non-hydro renewables should outpace nuclear power in 2018 if they did not already do so in 2017.)

All Utility-Scale Renewables Combined Exceed Nuclear Power in 27 states + D.C.:
