Honestly I feel like Jevons Paradox is a distinctly unhelpful way of phrasing phenomena, designed to create a feeling of novelty where there's none.

It's completely obvious that if you need energy, and you have energy source A and B (lets say natural gas and oil), people will use the one that is cheaper.

Oil became cheaper because a new supplier entered the market, and people started using more of it! Jevons Paradox!

The other explanation is that people have an outsize demand for a resource, and are actively making efforts to make it cheaper so they can use more of it, then when it gets cheaper, they use more of it.

Transistors got cheaper and we are using more of them! Jevons Paradox!
