Wind is now the largest single electricity generator in 7 U.S. states (for the year from Oct 1 '24 - Sep 30, '25):

SD, IA, KS, WY, OK, ND, NM

Providing up to 85% of demand (in SD)
November 26, 2025 at 7:54 PM
New EIA data

From Oct 1, '24-Sep 30, '25, 13 states generated 49.7-121% of their electricity demand with WWS

Wind was #1 overall generator 8 in states (SD, IA, WY, KS, ME, NM, ND, OK)

Hydro #1 in 3 (MT, WA, OR)

Solar #1 overall in CA and #1 WWS generator in NV

For the past year (Oct 1, '24-Sep 30, '25), South Dakota has generated enough WindWaterSolar to supply 121% of demand:

85% Wind
33% Water
3% Solar
-
121% Total

Montana haș generated 98% WWS

13 states have generated 49.7-121%% WWS

US avg: 25.1%

Breaking-New @EIAgov data Oct 1 '24-Sep 30 '25

More WindWaterSolar means much cheaper electricity

Of the 12 states with the most (50-121%) WWS supply as a % of demand, 11 have electricity prices 1.9-5.2 c/kWh below the US average

The fact the first thing listed to advance "American energy dominance" is vaporware (nuclear fusion) illustrates how out of touch @Energy is

Meanwhile, China in 2025 has already installed enough WindWaterSolar to power 55% of the US in 2050 for all energy purposes.

China’s diesel trucks are shifting to electric

"In 2020, nearly all new trucks in China ran on diesel.

...electric trucks will reach nearly 46% of new sales this year and 60% next year."

Less and less solar as the year winds down, but still 100% WindWaterSolar for part of the 218th day this year (67% of all days)

53% of all '25 demand supplied by in-state WWS (v 49.7% in '24 & 45.7% in '23)

Gas down 16% v '24 & 37% v '23
Demand down 2.1% v '24 & 1.4% v '23 due to growth of roof PV

As @mzjacobson.bsky.social says, there are no miracles needed. We have almost all the tech required to address human-caused climate change. But @doctorvive.bsky.social is right. We need the courage to deploy those technologies as rapidly as possible. 🧪🔌💡☀️💨💧🔋 www.iea.org/reports/worl...

Should Your Next Car be a Battery-Electric or Fossil-Fuel One?

If you really need a car, should your next one be powered by batteries or fossil fuels? Even if you don’t care about the planet, the answer is batteries.
