The problem with the "saving energy" argument is that it goes against our behaviour in all of recorded History. Mankind has always used more and more energy, and that use of more energy is entirely justified, as it has given us increasing quality of life. Quality of life translates to more than extra comfort. It means new purposes, new goals, new horizons.

If, apart from civilization de-evolution, we never lowered per-capita energy consumption in ~10k years, I have very little faith we can do it now.
