> 25% of electricity in the US was produced with renewables this year, more than both coal and nuclear [1].
That number includes hydro, and doesn't communicate the distribution of the generation, which is concentrated in the plains. Wind and solar are only ~16% of total, with the bulk being wind:
> For the six-month period to June 30, electrical generation by wind increased by 24.67% and provided 11.55% of total electrical generation. Meanwhile, solar sources grew by 27.72% and provided 4.94% of US electrical output.
It's also incredibly regional, with the least-dense parts of the US having the highest overall percentages. From the EIA report that link is based on [1]:
> The Southwest Power Pool (SPP) region has had the most growth in the renewable share of electricity generation over the past decade, largely due to wind generation. In 2013, 13% of the region’s electricity generation came from renewables. That share increased to 40% in 2021, and we expect it to rise to 44% in 2022.
> The Electric Reliability Council of Texas, or ERCOT, has also increased its renewable share, from 10% in 2013 to 32% in 2022. ERCOT is the only electricity market region where the renewable electricity share has transitioned from less than the U.S. average to more than the U.S. average from 2013 to present. Both SPP and ERCOT have added substantial generating capacity from wind turbines
So that's good, but it's a very different story than the top-line numbers suggest. If we're going to get to high levels of non-fossil electricity in the (far) more densely populated east and southeast, wind isn't going to do the job.

- timr 4y agoYes, I pulled the numbers from the link you cited. I'm just saying that the nuance here matters a lot, and isn't captured by the headline number. Barring some dramatic change in technology, we'll probably max out wind generation in the western US in the next decade or two, and it isn't a good solution for the most densely populated parts of the US. Solar isn't growing nearly as quickly (and of course, has the base load problem).
