The trouble I see is that new consumption matching (or even some locations where proposed DCs exceed) new green generation may not let us displace dirty generation such as coal, which we should be looking to eliminate.

The other issue that comes up with green generation is how variable it is, sometimes it'll be cloudy and still air, others will be windy and sunny, and the grid needs to capable of supplying everyone in both scenarios and not overbuilding generation they can't turn off. Having industries available to soak up an appropriate amount of energy available within their ecosystem would be great, but it's a hard sell to anyone to invest billions in sites where there could be no guarantees on utilization if they get bad weather for a few months. If there is any "plays nicely with others" regulation on consumption of a common resource, it's going to be reactive to problems than ahead of time.
