Except they do.
In case you're having trouble understanding that, the windfarm was producing 11,445 megawatts before the cold weather set in, and only 550 megawatts after the cold weather hit.
Yes that's even WITH "cold weather packages" wind turbines can't operate in -22F weather. Guess how cold it got in some parts of Texas? That's right, almost -20, throw in windchill and it was colder than -20, toss in some icy rain on top of that and it means bad news for wind turbines.
Texas experienced sustained cold weather it hasn't seen ever in recorded history. The average temperatures for the week were over 30 degrees colder than usual. You're pissed at politicians in Texas (because they're a red state of course) for not anticipating a natural event the state has never seen and most likely won't see again for at least a couple of decades.
Here's something that might shock you; most of California doesn't insulate their water pipes or prepare for this kind of cold weather either, and if something like this ever happened to California I feel safe betting money that you wouldn't dare blame a single politician (well you might find a Republican who said something you don't like and blame them) for not preparing for something that no one could have possibly saw coming.
