Well, in that case you'd also want to add in things like offshore wind capacity and large remote solar array capacity and remote energy storage capacity. A NYC apartment complex can no more be expected to be energy-independent any more than it can be food-independent.

Cities will always require the import of significant materials, food, and energy from surrounding areas, and electricity is actually a more efficient means of importing energy than natural gas is. Replacing all the diesel trucks and buses with electrical versions, that's equally desirable. Cities will become much cleaner places, which is to everyone's benefit.
