Your argument was Jevons Paradox, that consumption goes up as use gets more efficient. My counter argument was that my fridge got more efficient, but it will be difficult to use it more often since it by design runs all the time. Your counter argument was that I will now have more computers and whatnot and will still use more electricity. I replied to you that even this anecdotal evidence falls on its face because I actually have the data and that my electricity use went down despite moving to full time work from home. I think this sums it up nicely.

I also stated previously that we have the data even on a large scale. Electricity use in the EU went down in the last 20 years and this even with millions of EVs now compared to then. Even Norway which now for years sells almost exclusively EVs has had just a mild bump in electricity use compared to a decade before. This implies that The efficiency savings made elsewhere held. My hypothesis would be it's because at a certain point it's impossible to use something more than you already are (see fridge, dishwasher, induction stove, computers, TVs etc) and thus efficiency gains there will hold. The same pattern is observed with American gasoline use -- as the gas guzzlers of the 70s died off during the oil crisis, per capita gas use fell and practically never recovered. This despite the fact that this use case is quite comparable to coal and you could easily argue that with better mileage people will drive more. And they probably do, but still the gasoline use fell.

You argued further that developed countries need to account for energy use of products they offshored, but I offered data that says otherwise. Additionally the argument can't be used for gasoline use which as stated did not follow Jevons Paradox.

So obviously, Jevons Paradox did not hold in these substantial cases and should not be viewed as law of nature. It's an interesting observation that makes sense, but obviously has its limits.
