Data centers seem tangential to any real problem. The grid should be converting to green energy and regulation that says datacenters must also be power stations is backwards.

A gigawatt is a gigawatt. If you need a gigawatt, you pay for the generation and infrastructure to provide it, whether you're a million people or a single data-centre. The jursidictions that require data-centres to provide their own generation and electrical infrastructure are completely within their rights.
