"Texas produces more electricity than any other state, but only about one-quarter of it comes from wind and solar..."
Since when is 1/4 a small slice?
Don’t confuse capacity and produced volume of power consumption. Wind and solar is 25% of consumption not capacity. Wind is 31,000 megawatts of capacity. Last night 42,000 megawatts of gas coal and nuclear dropped off line and there was still 59,000 megawatts of.capacity of which only 4000 was wind and zero was solar.

2019 data
Production is but one segment of the power system.
