When we had the snowpacalypse it wasn’t because of wind or solar (ERCOT said it was) it was because gas generators were competing with homes whose heaters used natural gas.
Wind and solar were working quite well.
ERCOT is owned by Big Fossil (as are most agencies in Texas—corruption here is the norm, not the exception). It’s so bad that Abbot wants to play with small nukes instead of more batteries (despite Musk selling them). Nuke waste? Not his problem.
Reality is not a Texas thing.
