Nvidia's Water Solution Ends at the Property Line
Nvidia's warm-water cooling eliminates water use inside the data centre and nothing beyond it. The bulk of AI's water footprint, roughly 54% by the IEA's accounting, sits behind the meter in fossil fuel plants supplying the grid when renewables fall short. Until disclosure extends to end-to-end water intensity per compute-hour inclusive of generation fuel source, the industry is optimising for a boundary it drew itself.

Short of Space or Power
Microsoft is sitting on roughly $80 billion of Azure orders it cannot fill. It has the demand and it can buy the chips. What it cannot get is power.
