I assume energy use by electronic devices is a distant runner up of energy use compared to moving lots of mass (individuals + their large personal cars) lots of distance (to and from their large lots in far flung suburbs). And leisure travel of course, especially via airplane.

Oh, I bet you're right. I was only giving the first example that came to mind. I think transportation is a better example, a field where many cities (at least in the USA) could have better quality of life for less energy. When everyone drives their own car every day because public transportation is inadequate and inconvenient, we waste time every day stuck in slow traffic. With more convenient public transportation, the roads are more clear for cars, the air is cleaner, and people don't have to spend as much money on gasoline and car maintenance.
