My understanding is that the Governor and government are now officially saying that it wasn't due to lack of energy from Wind/Solar but the Natural Gas lines freezing up. That's probably a LARGE reason why people are stating it was for other reasons than the wind/solar problems that have been noted by some.
Texas relies on Natural Gas for Power, wasn't ready for the extreme cold

Sorry, it's behind a paywall, but here's a portion of it
Natural gas supply is critically low in Texas, are rolling gas outages next
Regardless, however one looks at it, the primary cause of this (whether one blames the renewable resources, or Natural Gas) is that Texas simply wasn't prepared for a cold snap. They had a warning that such could happen in 2010 but apparently no one took it seriously.
There's a WARNING going out to some regions of Texas that you need to take a look at your next electricity bill. Due to the Natural Gas difficulties, the price has risen exponentially. Some cities and counties restrict how much the price of energy can rise in a month and people in those areas should be reasonably protected to a degree against massive cost increases. However, a few areas are giving out warning that the price may rise over 9,000% so people need to make sure that they keep an eye on what the costs are running for their electricity that they do get...when they get it.
If it DOES rise that much though, I expect there will be a lawsuit and legal action to stop it from costing people so much, but something to keep an eye on after this entire crisis is over.
AS pointed out, other states and even Canada (which relies much more heavily on Wind/Solar than Texas or any other state in the US) has not had these problems. Kansas did not have these problems. Oklahoma did not have these problems. Most of it seems to stem (at this point), NOT on whether it is fossil fuels or renewables or even Natural Gas, but whether they were prepared to handle the temperatures that hit Texas.
HOWEVER...this is like a one in every ten year event. The reason Texas went independent for it's energy is because the cost to secure against the cold for something that only happens once in ten years was seen as unfeasible. That's still a good question. This WAS a hard snap of cold, but it might not occur again until ten years more have passed. Last time was 2010. Prior to that I think was 2003 or 2004. There has been a cost in lives though which is more significant than last time this happened, so it may change the dynamic and how it is viewed.
