Machine That Made You Laugh, How the First Mammals Appear, Increase in Efficiency Leads to More Consumption

In the 19th century, a series of technological advancements made coal use far more efficient. Steam engines, industrial furnaces, and mechanical processes improved so much that conventional wisdom suggested the need for coal would shrink—after all, if industries could do more with less, they would require fewer resources. But the opposite happened, and this surprising effect was observed by William Stanley Jevons, a British economist, who documented what would later be known as Jevons Paradox.

At the time, the dominant belief was that technological improvements naturally led to conservation. But Jevons noticed a different pattern—each improvement in coal efficiency lowered costs, making it more attractive, which in turn spurred economic growth and increased total consumption. His insights challenged the common sense of the era and sparked debate over whether efficiency alone could ever reduce resource use in a growing economy.

We have seen this paradox play out repeatedly in different domains. When cars became more fuel-efficient, people drove more miles, offsetting the savings. When digital storage became cheaper and more compact, the volume of data exploded. Even with energy-efficient appliances, households often used more electricity by running more devices, not fewer. The same pattern emerges time and time again: when technology makes something easier or cheaper to use, humans find ways to use more of it, not less.

It is easy to misunderstand this idea, especially when efficiency is often promoted as a way to reduce resource consumption. But history shows that making things more accessible usually leads to greater overall demand. The challenge, then, is not just about making processes more efficient, but also about understanding how human behavior responds to abundance.
