Cities are built and run with cheap FF energy, is my belief. They are "efficient" only when energy is cheap. You must expend energy to house the people in conditioned spaces, to provide illumination and network connectivity, to transport, preserve, and prepare food, to provide clean water and to dispose of wastes. All these things become very difficult with feeble distributed energy sources, in densely populated cities.
I believe that as energy costs increase, the cities will decline and decay.
