The situation with the electric grid is pretty crazy. The cost to supply power to houses in sparsely populated communities is orders of magnitude higher than urban apartments. Not just the power infrastructure itself but all sorts of little ongoing things like maintenance visits, as well as losses from transmission and distribution. I worked on smart grid systems and getting apartment buildings online was a piece of cake, with one simple connection handling multiple buildings with hundreds of meters, meanwhile suburban homes required much more expensive equipment that was more difficult for technicians to install and serviced only a handful of homes. Everyone talks about this as if these were humble shacks out in the boonies but the bulk of these service points are suburban McMansions built on cheap land at the margins of the cities. Broadly speaking this results is poorer ratepayers significantly subsidizing services for wealthier ones.
