Bullshit. EVs do not stay plugged in all the time. So the idea that they will be free capacity is a pipe dream. But let’s say that they do. My EV has a 100kwh battery (when brand new). The average household power usage in Florida where I live is 1500kwh/month, or 50kwh/day (obviously few people charging EVs). So assuming 100% efficiency, and assuming the pessimistic California brownout length of 2 hours (average is 1-2 hours), my EV could power 24 homes during one brownout before being fully discharged. Less than one percent of homeowners own EVs, and only about a quarter percent of renters, so we’re looking at having well less than a quarter of the power we need just for residences, assuming every EV was plugged in. Add in commercial power usage and the fact that people will still want to get around and you’ll find that EVs are not a viable power storage system. And they couldn’t have helped in TX where the outage was up to 17 days in some areas.

You keep pushing a false narrative of renewables failing in TX. Those failures are fossil fuel failures. More than half of ERCOT’s winter generating capacity, largely powered by natural gas, was offline due to the storm, an estimated 45 gigawatts, according to Dan Woodfin, a senior director at ERCOT: https://www.houstonchronicle.com/business/columnists/tomlinson/article/texas-grid-fail-natural-gas-coal-nuclear-18163855.php https://www.houstonchronicle.com/business/columnists/tomlins...

  Read my post. I never said that renewables caused the TX incident. I pointed out that outages happen, and that outages are more predictable and likely in the case of renewables. Oddly, the fact that fossil fuel sources were a precipitating cause in TX bolsters my claim, because removal of those sources from the grid supply could not be offset by renewables (some of which were also offline).
