Practical Engineering's explanation of the February 2021 Texas winter storm and the resulting power grid outage. It lays out the facts about ERCOT, the grid's isolation, and how generation across fuel types failed in the cold.
Whenever Texas grid failures come up, HN people link it as the calm, technically informed account that cuts through political blame.

For a really good overview of what happened in Texas I'd highly recommend practical engineering's video. He provides a technical overview of the entire situation that really helps explain why what happened, happened. this video
Practical Engineering made an outstanding video on this: "What Really Happened During the Texas Power Grid Outage?" this video
So, I've lived in Texas since the late 90's. There are certainly things that need doing. But this is not really a great analysis. A better analysis of the February grid failure is here: this video Long story short: 1) the population has gone up a lot, so all infrastructure (traffic, electricity, water, housing, etc.) has had to increase rapidly 2) the mix 10 years ago was a lot of coal and oil, now it is much more natgas, wind, and solar. These can be reliable, but they are very different than coal and oil, and therefore a lot of new lessons have to be learned. 3) a big reason for the surge in renewables is the way the market is designed, which lets them pocket big bonuses at peak demand times. Since this _normally_ is in the summer during the day, this makes solar a lot more competitive financially. Natgas certainly failed in February, but all three of wind, solar, and natgas had big problems, it was just that the natgas and wind were unexpected while the solar was not (in the winter at night). Thus far, the power grid is holding this summer, even though there is all-time record demand. We certainly do need to increase capacity, but that is mostly due to the surge in population, not any huge mismanagement. I'm sure it could be done better, but it's not unusual for record demand and a new mix of sources to put the system through a learning curve.
So, I wouldn't know, because I haven't watched Fox News in many years. The best low-emotion, technically informed analysis of "Snowpocalypse" is probably this one from "Practical Engineering", made by a San Antonio-based engineer: this video The outages were not from any one "main cause", except perhaps "Texas doesn't get cold that often and wasn't ready". But, wind icing up was certainly one of several major causes, along with natural gas pressure dropping so that natgas-powered electrical plants could not keep operating.
Ok, i'll bite. You know nothing about the operational details of power grid infrastructure in Texas and what lead to the problems encountered. Here is a good video explaining what happened: this video Just FYI, Grady from Practical Engineering channel who made the video is a civil engineer. I also recommend his entire series about power grid (well, actually all his videos are great). )
