I see Jevons' effect touted around a lot as if it's a law of nature when in reality it's just a name given an effect observed in very specific instances
Even within economics it's treated as a rare market effect and not as a given eventuality
It’s literally just a special case of the idea of price elasticity, a pretty core and uncontroversial idea in economics. For many (but not all) goods - if the price goes up, demand goes down. If the price goes down (due to efficiency improvements) the demand goes up.
If overall resource consumption stays the same or increases, then boom: Jevon’s paradox. And experience shows me that’s the norm, not an exception.
Have you heard of computers? Do you consider the development of computing power per Watt vs the total power consumed for computing over the last 70 years as an example of this rare market effect?
I agree that it's not a law of nature or economics, but it is a trap that we can fall into and that is why we have to be sceptical when we talk about technological solutions. Any efforts that try to make a harmful process less harmful can give a worse end result, because the improved processes will be used more than before because of efficiency gains.
