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 per cent 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 — not for lack of demand, and not for lack of chips, but for lack of power. The binding constraint on AI has quietly moved from the fab to the substation, and the hyperscalers' answer — become your own utility — is rational for them and corrosive for everyone else standing in the same interconnection queue.

field notes: the data centre learns to flinch
The demos are real and the peer review is real. What's unproven is whether a utility planner will write a 500 MW flexible load into a resource-adequacy filing and sleep at night. Watch the tariffs, not the GPUs.

Brussels wants to triple data centre capacity and asked you to switch off the dishwasher — on the same afternoon
Brussels filed two plans on the same afternoon that quietly cancel each other out: triple the data centres, and please switch off the dishwasher. It's a demand-management answer to a supply problem, dressed as industrial strategy.
