They are indeed the enemy. They've managed to convince a large swath of the population to hate everything that is not fossil-fueled.
Example: God made the sun and the sky. That's where heaven is. Fossil fuels come from under the earth. Something else really bad is down there too. I don't want to spell it out, but it's the opposite of heaven.
Or for the "independent, lion-not-sheep" types: I don't depend on big companies. My energy comes from up above. You can't take the sky from me. etc.
Freedom to power your home without paying "the man" should be compelling to all who could use it. Texas is ironically a prime state for renewable energy and the dollars generated from it have convinced some, but many still reject it as "wokeness".
It boggles the mind.
When I'm in public conversation, say in a coffee shop, restaurant, or crowded park, and I know I'm in a place with a lot of "christians" around me, I'll say things very much like you describe:
"Don't you know? Oil comes up from hell! It's made by the devil!"
"Sunlight is falling down from heaven, it's a gift directly from god."
"But for some reason, so many christians are against solar power, and want to burn more oil."
Then I'll wrap up with a little apocalypse evangelism:
"The bible says that in the end times, most christians will start to follow false prophets, and they're all going to go to hell!"
I doubt it has much lasting effect, but I do see a few heads turn, with questioning, worried looks on their faces.
You're the first other person I've seen mention this as a means of "converting the sinners".
Point your gun where it belongs which is the oil industry and its lobbyists.
