Maybe the more energy we consume, the more motivated we'll be to move to more efficient methods. And the available fossil fuels are projected to run out at some point, aren't they? So if we're going to use them all anyway before switching fully to 100% renewable/alternative sources, then using it up faster doesn't result in more total emissions, just more now and less later. After that, we'll be "wasting" hydro and nuclear etc., which doesn't really matter.
