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...
