Jevons Paradox

In 1865, economist William Stanley Jevons observed that as steam engines became more efficient, Britain’s coal consumption didn’t drop — it exploded. Technological improvements that increase the efficiency of a resource’s use lead to a rise, not a fall, in total consumption of that resource.

The mechanism works through two effects: the direct rebound (cheaper per-unit cost drives more usage) and the indirect rebound (savings get redirected to other resource-consuming activities).

Classic example: in the 1980s, computers were supposed to create the “paperless office.” Instead, because producing documents became so easy, global paper consumption tripled between 1980 and 2000.

The paradox doesn’t mean efficiency is useless — most economists find rebound effects don’t fully cancel out gains. But it warns that efficiency alone won’t solve resource problems without complementary measures.
