Energy savings of at least 40% are possible in the larger cities through changes such as increasing vehicle operating costs, increasing vehicle occupancy, higher-density development, and shorter-trip behaviour. Subcentre development within the urban area is found to be less energy expensive than fringe or satellite development.
