IN 1865, the English economist William Stanley Jevons wrote a book called The Coal Question. In it, he considered a paradoxical fact about technological progress.
One might assume that increases in the efficiency of burning coal would mean that there would be a corresponding reduction in its use because less was needed to achieve the same aims. But as Jevons noted, “it is wholly a confusion of ideas to suppose that the economical use of fuel is equivalent to a diminished consumption. The very contrary is the truth.”
The Jevons Paradox states that increases in efficiency lead to increases in demand. A century-and-a-half later, it remains depressingly relevant.
