Da un articolo su The skeptical optimist:
Keep that in mind, because if there is one certainty about our future, it is this: our energy usage will grow in lock step with our standard of living—energy conservation measures notwithstanding. (Conservation measures reduce our energy usage per standard-of-living-dollar, enabling our standard of living to increase at a faster rate, which in turn will increase the total amount of energy we’ll use. Sounds counterintuitive, but it’s the one sure bet about our energy future: Energy efficiency improvements will help drive increased energy usage.)
