Well, it could have something to do with right wing weirdos slamming wind farms as the reason for all failures of Ercot. And the article bringing up the winter issues when mostly the gas/thermal plants failed. And not mentioning the fact Ercot decided out to be a part of a bigger market that could help the situation by trading the energy with other states. And the capacity planning issues.

Instead it effectively says: look at this graph, wind doesn't solve all our issues, so we're going to call it the reason instead. It's a shallow opinion piece not a serious article.
