There's a new November electric demand record in Texas. It's 92 degrees in Austin – on November 7. There are 25,000 megawatts-worth of thermal plants offline for seasonal maintenance. Solar + wind providing >50% all day. Could see a battery record this evening. #txlege #txenergy

82% of new US energy capacity = solar + storage.

The Trump Administration just issued a new order trying to kill solar and wind because they allegedly use too much land. But somehow this new fervor for "capacity density" won't apply to ethanol, which uses 100X as much land as solar per unit of energy.

Yeah, enough already with the uninformed hot takes
Nice explainer, but I'm not convinced that inertia was the issue here. And I don't think we'll actually know until we understand 1) what caused a frequency issue in the first place, 2) what generation (and interconnections) tripped offline and why, and 3) how fast frequency dropped with those trips.
"That a renewables-heavy grid might struggle with maintaining reliability thanks to low inertia is no surprise," writes @zeitlin.bsky.social.

Below is how corn is used in the United States. See if you can spot 2005-07, when U.S. federal policy began to incentivize corn ethanol (in orange in the chart) in earnest. In recent years 35-40% of the U.S. corn supply has gone to biofuels. This supplies less than 5% of U.S. transportation fuel.

There's a new solar record in ERCOT. A few minutes ago, solar exceeded 25,000 megawatts of production for the first time, equaling 52% of demand. Emission free sources (wind, solar, and nuclear) are producing about 75% of power demand today.
