At least in my part of the US, the datacenters built (and planned) are not running their own gas generators, but are just as hated here as they are most other places due to the other adverse impacts they have.
That one in utah everybody hated was gonna be built in an empty valley. There would have been no impact to neighbors because there weren't any, and no impact to the grid because they planned to build their own nuclear power plant.
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.
