The current thing with "AI Water Consumption" is to talk about the water consumed by the _power plant_ in addition to direct cooling costs.
Which you can factor in, and probably should in some way, but you _need_ to acknowledge two things.
1. Water "consumption" for power is not the same type, loss, or community impact that water to direct cooling costs in data centers tends to be.
2. It's _still_ like an order of magnitude beneath corn. Let alone the rest of agriculture. It's also below lawns and golf courses.
There are really good criticisms of these data centers, those criticisms _should_ be brought up. But you don't need to pick the weakest points, lie, or exaggerate to make those points. You really don't.
