It did drop in the us over the past decade though (for various reasons). I think it is possible, but would require something drastic changing about the way people work/live. If more people worked remotely, better infrastructure for a local lifestyle, etc, etc. The US average is like 12 kW per person, the world average is I think about 3. Surely it is possible without conflict, just requires the magic combination of better and more efficient. I keep thinking recently how it has changed from everyone watching one big tv and fighting over the channel, vs watching whatever you want on your mobile device. It is worse and better at the same time and probably more energy efficient and has become the norm. Makes me wonder what is the equivalent for transport, etc?
