AI data center water use looks small in aggregate but still local

Ars Technica takes a closer look at how much water AI data centers use in the context of total water consumption.

The aggregate numbers may be smaller than the public debate suggests, but that does not make the issue irrelevant. Water stress is local, and a facility can matter a lot in the wrong place even if the national share is modest.

For AI infrastructure, the takeaway is that sustainability arguments need geography, not just big totals.
