Are you talking about the Box Elder County Stratos project? I did some digging into that. AFAIK, they are mostly going to be powered by a natural gas pipeline. I haven't heard of them using nuclear. Got any links?

It is in a remote valley. And, it's going to use less groundwater than the previous use of the land. The only things to really complain about are huge amounts of gas consumption and AI bad. If the locals pinned them down to building out solar and mini-nuke power, the only thing left would be AI bad.

They are being built to support an industry which is itself an adverse impact.
