Both solar and wind were down. Wind turbines in Texas aren't weatherproofed either (cost) and it was generally dark and overcast. This didn't really matter since wind generation is a pretty small percentage of the grid and it was mostly gas generators (companies that produce natural gas for use in generation) that were the issue, but "more solar and wind" would have done nothing. The correct answer seems to have been forcing the gas generators to winterize.
