New report reveals that renewables are now providing more electricity than nuclear power in over half the US states and more electricity than coal in a third

Regardless of the policies of the Trump administration, the momentum to deploy renewables in the US is gaining strength. Kelly Pickerel explains in an article on the Solar Power World website.


Renewable energy provides more electricity than nuclear power in over half of U.S. states

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 latest “Energy Infrastructure Update,” renewable sources now account for 20.66% of the total available installed generating capacity. That is more than double the generating capacity of the nation’s nuclear power plants (9.12%) and is rapidly approaching the capacity of the nation’s coal plants (23.04%), which has dropped precipitously from 28.90% 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 which could account for an additional 30% or more in solar capacity.

Renewable energy critics are quick to 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% of the nation’s electrical generation during the first five months of 2018 compared to 20.14% from nuclear power. In fact, during the two most recent months reflected in EIA’s data (April and May 2018), renewables provided 10.6% more electricity than did nuclear power. (Renewables also similarly 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% for the first five months of 2018) than renewables, it is in a tailspin — dropping from 39.0% five years ago — while renewables have grown from a 14.3% 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 (Colorado, Maine, Oregon, Vermont). Consequently, renewables are now providing more electricity than nuclear power in 27 states plus Washington, D.C.; solar (utility-scale and distributed) alone is outpacing nuclear in 21 states while wind alone already exceeds nuclear in 22 states and is rapidly closing the gap in others. Even in six states still using nuclear power (California, Iowa, Kansas, Minnesota, Texas, Washington), 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,” noted 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 simply can’t compete with renewable energy,” said 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 precipitous decline as coal in the coming years.”

  1. Monthly data can be interesting, but annual numbers are also important. The presentation here hides the US total annual picture, since solar and wind are highly seasonal, electric utilities often cover more than one state, and interstate transmission is substantial. Solar and wind are highly desirable up to some percentage of total generation, but that “most useful” percentage is not known yet, and depends on transmission capacities and potential battery or other storage.

    The 2017 annual electric generation percentages for the US are:
    2017% coal gas nukes hydro wind solar
    30.1% 31.7% 20.0% 7.5% 6.3% 1.9%

    1. Hi Mike
      I fully agree about the need for annual numbers. There are so many factors that can influence monthly data. I appreciate your two comments.
