2. Gas turbines being used by these companies, because America stopped investing in the grid for ~20 years. This is real noise and pollution people don't want, and then they see EOs that undo the very environmental protections meant to keep them safe and healthy.

There is an interesting story (retold by Asianometry iirc) about China fumbling the first few trash incinerators, learning from that, and have now built almost 1000 of them without much fuss. One of the interesting things I learned is that the Chinese people protested, were allowed to protest, and the government listened. (note, they were not protesting the CCP)
Being more of an engineer than a politician, I thought it was a good idea technically and socially for all of the parties involved in any specific location.

The technology ouroboros is gonna eat us all eventually it seems. :|
