Texas actually does better in the renewable energy front than you may expect.
A quarter of the state’s energy is produced through wind and solar. The biggest bottleneck preventing more wind adoption is the capacity of transmission lines up and the lack of energy storage.
The advantage of natural gas is that it can be dry up pretty much anywhere and isn’t dependent on weather.
The biggest problem Texas has right now regarding energy (and housing costs, and inflation, and municipal planning, and traffic, etc) is its extremely rapid population growth.
Yes, the heat wave is historic and ERCOT is awful, but even in perfect weather the grid is being stressed from the sheer number of people and businesses moving here
