I don't think many people on the right have ever been against solar power. It's rather being pro all power and not wanting to remove a source to replace it. The demands to remove power sources come from the left. Build as much solar as you want, but don't shut down the nuclear plants.

The current US administration has forcibly shutdown solar, onshore and offshore wind projects. Explicitly, intentionally.

A bit of realism would help here. Yes, there's a left/NIMBY overlap to some degree, but the forces from the non-right camp seeking to limit power development comes from the NIMBY elements, not the left elements.

A bit of realism is that there's a very well established anti-nuclear popular movement on the left, which has existed for decades. As long as we have access to history books and photos from the past, there is no use denying this.

Germany recently finished their complete dismantlement of the nations nuclear power. Another nuclear country Sweden, has shut down seven of their reactors, but are at least rhetorically changing back to supporting nuclear.

Go and talk in real life with people on the left and you'll find many of them are against nuclear power. Go and talk in real life with people on the right and it will be hard for you to find anybody who is against solar power. Because why would you be against solar?

The problem is left and right are too broad. There are some one each side in every different option. There are oil barrons in the right and those who like solar because it is economical. Likewise the left has those who hate all electric and want to go back to the pre electric era, and those who want solar.

People who have no other arguments than Reddit down votes: Try to get out of your bubble and sit down and talk with somebody on the right IRL and see if they have anything against solar power. I've never heard anybody in my life be against it, so maybe you are just swallowing untruths because they align with your taste.
