The head of the main oil/gas regulator in TX has released a statement confirming my analysis that "the root cause of the TX blackouts is a national and state policy that has prioritized the adoption of unreliable wind/solar energy over reliable energy."

"ERCOT was notified over a decade ago that TX power plants had failed to adequately weatherize....Instead of spending our resources making our grid more resilient, policy and spending has focused on mandating or subsidizing wind and solar to expand their presence on the grid.

"The takeaway...should not be the failure of fossil fuels, but the failure of leadership at ERCOT and the dangers of relying on intermittent, unreliable forms of energy like wind....Had TX been using 100% renewables, we would have had 100% blackouts."
