Natural gas is a big part of the problem here - the deep cold has severely impacted production and distribution. Texas has little natural gas storage like they have back east. Power plants cannot burn gas they do not have. Like all major man-made disasters, there are multiple points of failure here, renewables are just part of the story. And all points need to be addressed. And making power generation resilient and redundant will mean higher bills - for events that happen about once a decade.
“And all points need to be addressed.”
Oh, they’ll address it. They’ll address your right into a concentration camp.
