How much of that 15% drop can you explain with light bulbs and heat pumps? There is no way it is that material. And we know that efficiencies don't cause the amount of energy used to drop, they cause an overall rise, because energy goes further so it is worth collecting more (ie, Jevons' Paradox). The only thing that causes energy use to drop is if the supply isn't there. > Many countries have decoupled economic growth from energy use. Yeah, but the obvious conclusion isn't what you expect it is - GDP is becoming obsolete. The reason it has been useful historically is that it is a good proxy for energy availability. You've got a number there that goes up, but is decoupling from any real metric. If GDP correlates with energy availability and GDP drops; that is an urgent problem because that means it is getting harder to get food, shelter and essentials. If it doesn't correlate with energy availability then there is a bit of a question about why we're supposed to care.
