Coal piles freezing solid because there is no roof, gas valves impossible to operate because nobody would put a box around them, no water too cool reactor cores because the pipes froze: these are not failures somehow cascading from the fact they build some windmills.
The failure point was a repeat of previous cold events -- it wasn't really a cascade event, of course, given wind turbines provide only 20% of power on the ECOT mini-grid.
Given there are similar capacity wind turbines running happily in Antarctica, and the heads-up from the 2011 & 2019 events to winterise the Texas fleet, it's difficult to see how this is a 'windmill problem'.
> ... but having so much capacity invested in unreliable wind generation was a very significant contributor to the blackouts that should not be ignored.
Has that grid suffered lots of blackouts at times other than big freezes?
If it hasn't, then that would suggest that the designers / operators of the grid factored in the unreliability of wind, and have the baseload well covered by gas, nuclear, etc.
> ERCOT is a world leader in wind production, and that was pretty punishing when its 25GW of wind capacity was producing 0.
And yet:
"About half of the state’s wind capacity was offline Sunday because of turbines that had frozen in west Texas, according to the Austin American-Statesman, but high winds from the winter storm were spinning coastal turbines faster and generating more power to offset those losses." [1]
> Winterization would have helped somewhat with less turbines freezing, but it doesn't help at all when the wind stops blowing.
'fewer'
I'm not sure where you're getting information that the wind stopped blowing, or why that's a reason to not use wind turbines as part of an overall power generation strategy, or indeed why you seem to be surprised that if ECOT prepared wind turbines, as well as gas & nuclear (which both lost a fair chunk of capacity) then the outcome wouldn't have been so appalling.

Blames turbines for not working when it freezes.
I'm so freaking tired of hearing this.

Wind ran at about 50% of capacity and that was because it wasn't winterized.
(For those who missed it, the parent is asserting that "windmill" should be reserved for wind-powered mills.)
In the case of wind turbines, it is clear that the generation unit is its mill, so I have no quarrel with calling them windmills.
They may be considered only half-satanic, having only three blades.
