Honesty I don’t really think the main point should be about solar, nuclear, whatever. If the energy was still going to be used for something else then it’s zero sum from their point of view. It should be about trapped or very low demand times / locations. Energy that would not have been used otherwise or generation that would not have been economically viable without bitcoin as a base load demand creator. #[2]​ had someone on his show from Texas Blockchain Council(sorry if I butchered the org name) recently that was talking in this area. They did quite put it the way I stated it but was along the same lines.
