……………The Jevons Paradox
But there is one aspect of Jevons’s argument—the Jevons Paradox itself—that continues to be considered one of the pioneering insights in ecological economics.8 In chapter 7 of The Coal Question, entitled “Of the Economy of Fuel,” Jevons responded to the common notion that, since “the falling supply of coal will be met by new modes of using it efficiently and economically,” there was no problem of supply, and that, indeed, “the amount of useful work got out of coal may be made to increase manifold, while the amount of coal consumed is stationary or diminishing.” In sharp opposition to this, Jevons contended that increased efficiency in the use of coal as an energy source only generated increased demand for that resource, not decreased demand, as one might expect. This was because improvement in efficiency led to further economic expansion. “It is wholly a confusion of ideas,” he wrote, “to suppose that the economical use of fuel is equivalent to a diminished consumption. The very contrary is the truth. As a rule, new modes of economy will lead to an increase of consumption according to a principle recognised in many parallel instances….The same principles apply, with even greater force and distinctness, to the use of such a general agent as coal. It is the very economy of its use which leads to its extensive consumption.”……………….
