It is especially important for the leaders and policymakers to understand the nature of the Jevons Paradox, it is important in relation to the Sustainable Development Goals because it challenges the narratives behind sustainable energy policies striving for improvements in energy efficiency.

History of Jevons Paradox?

The Jevons paradox was first introduced by the English economist William Stanley Jevons in his 1865 book the "Coal Question". Jevons observed that England's consumption of coal soared after James Watt introduced the Watt steam engine, which improved the efficiency of the coal-fired steam engine. Watt's innovations made coal a more cost-effective power source, leading to the increased use of the steam engine in a wide range of industries. This in turn increased total coal consumption, even as the amount of coal required for any application fell. Jevons argued that improvements in fuel efficiency tend to increase (rather than decrease) fuel use.

The Jevons Paradox is the most widely known paradox in energy and environmental economics today.

Here is why

Many scientists and policymakers argue that future technological innovations will reduce consumption of resources; the Jevons Paradox explains why this may be a false hope.

Here are some examples to further explain this Paradox

1. Economists have observed that consumers tend to travel more when their cars are more fuel efficient, causing a 'rebound' in the demand for fuel. This means that, a decrease in the cost (or price) of a good or service will increase the quantity demanded (the law of demand). With a lower cost for travel, consumers will travel more, increasing the demand for fuel.

If cars are more efficient, it will simply lead to more driving

2. What about Water Usage? The more efficient the water processing/ or treatment is, will lead to more water consumption.

3. Here is a sad example, the expansion of slavery in the United States following the invention of the cotton gin (end of the 18th Century) caused the growth of slavery. While it was true that the cotton gin reduced the labor of removing seeds, it did not reduce the need for enslaved labor to grow and pick the cotton. In fact, the opposite occurred. Cotton growing became so profitable for enslavers that it increased their demand for both land and enslaved labor.
