- actually_a_dog 5y agoNo.... the amount of energy consumption is unsustainable at any efficiency level. But, what I think you're saying is that if we can increase efficiency by X%, then we can still sustain current economic output, yes? Well, considering we're 70% over the sustainable level, that means we'd need to get 58% more efficient, with no increase in consumption, in less than 20 years. How likely do you think that is?
