“Almost nobody has gas heat in Texas”
That’s incorrect. Approximately a third have gas heat per https://www.eia.gov/todayinenergy/detail.php?id=47116
By your own source that's 50% higher electricity dependence for heat than the U.S. average.
But no, I was not talking about the upper latitudes of Texas where freezing weather and snow is quite common and gas heaters are more prevalent.
Of course, if the fans are electric, then the gas heat doesn’t help.
In that case, you better hope you have a gas fireplace.
