Water.

A few things about the water consumption.

Without a doubt, and it's wonderful to see it getting more attention, AI and data centers globally consume tremendous amounts of fresh water, a couple percent.

But even that number is difficult to measure because one of the first questions, for the direct on-site water use, right, is this water actually consumed and not returned to the watershed, evaporated off as part of cooling, or is it direct cooling and therefore doesn't leave the watershed? And so the way we think about what does water, quote, use even mean can be confusing to folks.

And then offsite, you know, we have electricity generation.

Well, that electricity generation, where does that cooling come from? There is a big water footprint there as well.

And then, of course, there is water consumed in the manufacturing of chips and servers and construction materials.

not just what AI can do, but what it should do and how consciously we choose to use it.
