If they pay to power it with sustainable energy then it doesn’t. Simple as that. Energy use is really not a problem.

It is if doing so means taking up existing capacity in sustainable energy.

If they were always adding new sustainable capacity specifically for their data centres, that would be one thing, but if all they do is pay for the use of existing capacity, that potentially just pushes the issue down the road a bit.

If/when there’s enough capacity to supply all homes and businesses then this issue would disappear, but I don’t know how close that is.
