2020 US electricity generation data are in from the US Energy Information Administration. Crunching the numbers, renewable energy accounted for 20.6% of US electricity generation last year.
That was led by wind power, which accounted for 8.3% of US electricity generation, followed by hydropower at 7.2% and solar power at 3.3%.
As reported last month, 77–80% of new US power capacity came from solar and wind power in 2020. However, power plants typically last decades and it takes a long time for significant changes in electricity generation to show capacity trends.
If we look a little bit further back in the electricity generation data, we can see that renewables are indeed growing their share of the electricity generation pie. In 2018, 17.5% of electricity generation came from renewables — 6.5% from wind power, 6.9% from hydropower, and 2.2% from solar power.
If you did a simple extrapolation using that 2018–2020 timeframe and extending the trend to 2030, renewables would rise to 36.1% of US electricity generation by 2030, with wind rising to 17.3%, hydropower to 8.7%, and solar power to 8.8%. However, that ignores the fact that solar power capacity has been growing increasingly faster in recent times. It’s more likely solar power would grow faster and the others perhaps slower. In fact, it was just a few months ago that the International Energy Agency declared solar power the cheapest electricity in history, and it was not long before that that Tesla rolled out record-low rooftop solar power prices. There is certainly an enormous amount of potential for greater solar power growth in the US in the coming decade.
Getting to the other side of the table, the biggest loser from 2018 to 2020 in the electricity sector was coal, which dropped from 27.3% of US electricity to 19.1% of US electricity. Actually, coal was the only source with a notable drop in US electricity generation. Natural gas saw its share rise from 34.9% to 39.9% and nuclear saw its share rise slightly from 19.2% to 19.5%.
If you follow climate science and air pollution news closely, then you are probably already grumbling and grunting that 36.1% renewable energy share of US electricity generation in 2030 just doesn’t cut it. Indeed, the transition to clean electricity needs to speed up. Perhaps the more significant renewable energy domination of new power capacity will help. Renewables grew from 18.3% in 2019 to 20.6% in 2020. A 2.3% increase in renewable energy share each year would at least lead to 43.6% renewable energy share by 2030.
We’ll see, and CleanTechnica will certainly be tracking it, as we have been for the past decade.
Regarding the month of December, that is typically not the best month for renewables, and in 2020 the share came to 20.1%, a bit below the full-year total of 20.6%. Though, wind and solar accounted for 11.6% in December just as they did for the year as a whole. And the year-over-year increases in the month of December were as follows:
|Source||December 2018||December 2019||December 2020|
|Solar + Wind||8.5%||9.4%||11.6%|
Do you have any additional thoughts on the December or 2020 electricity generation split in the United States, or in the trends from 2018 through 2020? If you have any forecasts to share for the coming decade, feel free to chime in down in the comments with those as well.
In the meantime, if you don’t have solar power and can get it, do so now! There are still great federal incentives as well as record-low prices. If you want to go with conventional solar PV via Tesla or a Tesla Solar Roof, feel free to use my referral code for a modest discount: https://ts.la/zachary63404
If you’d like to install small-scale wind power or hydropower on your property, sorry, I can’t help you with that. 😀

As an addendum, here’s our latest US power capacity report, referenced above:
According to new data from the U.S. Federal Energy Regulatory Commission (FERC) — data derived from Velocity Suite, ABB Inc. and The C Three Group LLC — solar power and wind power accounted for 77.1% of new utility-scale power capacity in the United States in 2020 (chart above). Adding in a CleanTechnica estimate for rooftop solar power capacity, that percentage rises to 80.1% (chart below).
Using the first group of figures (excluding rooftop or small-scale solar power), another 1% of power capacity came from other renewable energy sources and 21.8% came from natural gas.
Using the second group of figures (with a CleanTechnica estimate for rooftop/small-scale solar power), natural gas accounted for 18.9% of new US power capacity in 2020.
In the month of December, 99% of new power capacity came from solar and wind power, while natural gas contributed 1% of new power capacity across the country.
Considering politics for a moment, recall that Donald Trump said he’d revive the coal industry. In actuality, there was no stopping market forces and the coal industry continually collapsed under Trump, including in the last year of his presidency. I will return to the long-term collapse of coal in another article. However, while coal did continue to decline and renewable energy — most notably solar and wind — rose, the growth of solar and wind power slowed under the Trump administration, which had several fossil fuel industry insiders running major US departments — Department of Energy, Environmental Protection Agency, Department of Interior. Under President Biden, solar and wind power are expected to grow faster again. The point is not to beat 80% of new power capacity coming from solar and wind as much as it is to increasingly retire fossil fuel power plants while using more and more electricity from renewable energy sources.

Notice the trend?
Total installed power capacity in the country still shows the dominance of fossil fuels — natural gas and coal. I’ll come back to that soon in our next US Electricity Generation Report.
