Solar panels and batteries enabled the Texas power grid to function correctly even in the face of record demand.

Chris Conaton@conatonc.bsky.social

A familiar story for anyone who follows @volts.wtf. “The Chronicle spoke to more than half a dozen grid experts…to try to understand why Texas’s notoriously unreliable grid had a remarkably reliable summer. The answer was unanimous: solar panels and batteries.”

houstonchronicle.comTexas shattered energy demand records this summer. Here's why the grid held up.Texas repeatedly broke electricity demand records this summer, but ERCOT avoided emergencies as booming solar and battery capacity helped keep the grid stable.

The current El Niño is likely to be the largest in at least 1,000 years and will pile extra heat into an atmosphere in which temperatures are already rising rapidly due to human-caused global heating. This double whammy means 2027 is expected to become the hottest year ever recorded.

Number of 25C days each year at #London Heathrow from 1949 we see 2026 with 82 days is far exceeding all historical precedent. The former record year 2018 now eclipsed by 20 days and we're not done either. Remarkable year.

Capping off an historic summer, August 2026 also becomes the hottest August on record in London. An average temperature of 21.6C at LHR which is +3C above 1991-2020 climo. It is the 5th consecutive month to break a monthly record like this, we've never seen anything close to this.

There’s been a huge increase in extreme heat across Florida! Look closely: In the blue 1950s #Florida averaged 20-30 days a year with a heat index of 100°+. Now in the red that number has 2X, 3X or even 4X due to hotter and more humid weather. It’s not coincidence, it’s climate change!

“The Environmental Protection Agency has estimated a 10% to 30% drop in gas vehicle fuel economy in cold weather.” So EV range reduction is only slightly worse than gas cars.

Electric vehicles lose some range in the winter — and, to a lesser degree, in the summer. But exactly how much? AAA has brand-new data.
