The US has district heating systems. The country is very big and varied, as much as people like to paint it as homogenous.

And district cooling.

When I lived on a chilling grid, my summer AC bill was around $80, while friends whose buildings weren't connected paid $200+.

Are they doing anything with that heat, or are those savings from the scale they're operating at?
