One of the main arguments again the potential of energy efficiency as a possible (part-)solution to the global warming challenge is the so called rebound effect (a.k.a. the Jevons paradox). It is a real, empirically provable problem: once the efficiency of use of a resource (e.g. electric energy) increases, there is a tend to increase its consumption (instead of a decrease, which one would actually expect). However, in this post it is shown in an interesting way that relying too much on the knowledge about this effect and on common sense sometimes produces strange outcomes. Reality isn’t as simple as one may assume (e.g. claiming that the Jevons paradox is always valid).
