Jevons Paradox

I bought the highly praised book The Ministry for the Future. Unfortunately. I couldn’t complete it, gave up half way. The book has so much exposition that at times I forgot where the story was and who were the characters.

But there was one paradox mentioned in the book that caught my attention.

Jevons Paradox proposes that increases in efficiency in the use of a resource lead to an overall increase in the use of that resource, not a decrease. William Stanley Jevons, writing in 1865, was referring to the history of the use of coal; once the Watt engine was introduced, which greatly increased the efficiency of coal burning as energy creation, the use of coal grew far beyond the initial reduction in the amount needed for the activity that existed before the time of the improvement.

The rebound effect of this paradox can be mitigated only by adding other factors to the uptake of the more efficient method, such as requirements for reinvestment, taxes, and regulations. So they say in economics texts.

The paradox is visible in the history of technological improvements of all kinds. Better car miles per gallon, more miles driven. Faster computer times, more time spent on computers. And so on ad infinitum.
