Texas power outages vs. renewable energy

Here's the context:

Texans try to conserve heat and water as plunging temperatures knock out utilities and cell service

Quote:

More than 4.3 million households and businesses were without power in Texas on Tuesday morning as a result of a winter storm and freezing temperatures that swept into the state Monday. The entire state was below freezing early Tuesday, and utilities have been knocked out or frozen over by the bitter cold -- leaving many without primary means of heating their homes.
But then there are also this:

In Texas there is about $60 billion worth of wind, $9b of solar, $7b for the transmission to enable them, all sitting pretty much useless during this catastrophe.

Essentially all new investment is due to be the exact same stuff.

$76 billion of cheap energy is costing lives.
I am seeing (on social media) lots of accusations that the current power issues in Texas have been greatly exacerbated by reliance on renewable energy.

Yet, the weather in Texas is only extreme by Texas standards for winter. What they are experiencing would be considered positively balmy by the standards of winter in Wyoming, or Michigan, or really fully 50% of the lower 48 states.

And - power is not the only issue in Texas, cell towers are going out as well - is that tied to the power outages? (i.e. running out of backup power supplies).

I am hearing that the issue may be more that Texas had isolated its power grid from the rest of of the U.S. as a means of avoiding some federal regulation. They point out that Oklahoma is getting much of the same weather, and is not experiencing anywhere close to the level of outages that Texas is getting (more people in Austin without power than there are people in all of Oklahoma).

As for the weather knocking out alternative energy sources. How? As I said, Wyoming gets some pretty extreme weather and its wind farms still seem to work just fine. Colorado gets snow but still has a lot of rooftop solar, it is economical despite the occasional cover of snow.

They claim that the weather is even impacting coal and gas plants. Is that through interruption of supplies?

I am mostly interested in the renewable energy aspect of things here. There can often be a lot of deliberate misinformation and accidental false information via wishful thinking associated with the topic. As I said, I am seeing a lot of chatter on this subject - twitter, FB, Quora, all that.
