They use a small amount of land per MW used. The fact that space isn't a constraining factor in power demand, and demand for AI compute seems to be insatiable at the moment, means that there is less of a "land constraint" to use even more energy. If they actually required a lot of land they would be less viable and AI progress would be slower IMO. Just means even more data centre's will be built - this is where the Jevon's paradox actually is IMO. Seeing it in real life already with these things taking a significant portion of power demand and projected to take even more.

As you use more and more land as well the ability to provision renewables decreases - in general renewable power needs more land/resources per energy produced. You can't just mine it out of the ground; they just aren't as dense of a form of energy. Which means we either build less data centres to make room for renewables and transmission infrastructure associated with them, or more likely with lax regulation builders switch to more dense power sources (e.g. gas peakers, generators, etc) even if it is for supplementation.

I can see a future where data center wants are put ahead of communities paying tax on said infrastructure. In fact I think its happening in some places already.
