Every place I can think of residential water and electricity rates are a whole different animal than commercial and industrial rates.
In my town in particular, the marginal rate for *residential* water use shoots up by a factor of 4 once you go over the threshold for regular domestic consumption. Cook and clean, and you pay a few hundred per quarter. Water your lawn and it's a few thousand.
I imagine if the leftyloons around here ever allowed a datacenter, the water commissioner would be purchasing service trucks with solid gold steering wheels in short order from all the profit such a heavy water user would generate.
Same with power. And taxes. Industrial and commercial property subsidizes a whole lot of infrastructure.
This Austrualian thing is a grandstanding no-op at best.
