People sometimes confuse the Jevons Paradox with rebound effects in general. Reminder: "The Jevons paradox occurs when the rebound effect is greater than 100%, exceeding the original efficiency gains." "People save on electricity by replacing incandescent lights with LED lights, and also make their living rooms 25% brighter at the same time" is an example of a rebound effect. Some of the efficiency gain on the input side is offset by increased output consumption. But it's not an example of the Jevons Paradox. If you replace light sources with ones that are 5x as efficient, you'd have to also use more than 5x as much lighting as before to qualify as a Jevons Paradox. The Jevons Paradox is a specific, fairly narrow, empirically observable phenomenon. Fatalistic notions that technological efficiency improvements can't reduce per-capita energy consumption, "because of Jevons Paradox," are not empirically supported. Energy rebound effects are common, but when the rebound is less than 100% (as it usually is) then there are real net energy savings and it's not a Jevons Paradox.
