Electric cars are causing exactly the same problem.
Also the "recs" appear to be based on a lie. Overall, an increase in load can only be green if there is added new green generation to service that load.
Except the alternative to electric are petrol/diesel cars which are worse than electric cars run on gas or coal. The pollution no longer occurs in population zones, and the grid can be cleaned up without changing the car.
The alternatives for these data centres are either build renewables or not build the data centres, both of which are better.
