It’s not clear to me who to believe. This fact check claims only 4 GW of wind power was down but the link that precedes that claim doesn’t actually state that. Meanwhile the WSJ article (https://www.wsj.com/articles/a-deep-green-freeze-11613411002) claims 42% of power came from wind in the week before the freeze but there’s no sourcing of that either.
Believe primary sources that you can read and understand yourself. That’s it. Sad that we’ve come to this, but I had to adopt that policy last year for obvious reasons.
This other source claims 16 GW of renewable energy, mostly wind, is offline as compared to 30 GW of thermal sources (gas, coal, nuclear). That’s a very different claim from Politifact’s figure of 4 GW of wind offline. However Politifact frames it as 4 GW of wind experiencing problems (presumably meaning freezing problems and not just lack of wind). That seems like a spin of a different kind from the WSJ editorial.
EDIT: even more bizarrely, a different fact check from Politifact relating to the Texas outages claims yet another loss figure for wind power of only 2 GW, disagreeing with their other fact check: https://www.politifact.com/factchecks/2021/feb/17/tucker-car...
