Ken Paxton, who is running for Senate and currently serves as attorney general, proudly announced cracking down on "solar scams": https://www.texasattorneygeneral.gov/news/releases/attorney-...
Plus his campaign site makes no mention of supporting clean energy: https://www.kenpaxton.com/
I will repeat: it's political suicide to run on a platform of clean energy or education in Texas. That does not mean companies are not building clean energy. But politicians will not make it part of their platform during elections.
If you really think Republican voters in Texas care so much about it, wouldn't the obvious play for Democrats be pointing out how much green energy these Republican politicians have allowed to be built under their watch? I think you're painting Republican voters with an extremely broad brush here and honestly, fail to understand what exactly they object to in the first place regards to green energy. Their main objection is being _forced_ to use it (or being chided by ivory tower know-it-alls) in contexts where they have certain preferences (like driving a big ass truck).
Not a single one is going to object to cheap energy so long as it doesn't degrade their current lifestyle. That's the point people like you forget when you're creating Republican straw men.
I’ve seen too many solar panels installed on the north side of a house, under a tree.
