He must cook a really lousy baked potato.

The other thing that skews this Greg foots figures, is his use of just the homes smart meter readings, having switched a few big appliances off not a dedicated energy plug monitor, so the load on the house elsewhere... more fag packet & less fact.
& jesus, if the fella cannot swirl a spud in a bowl of olive oil & a bit of garlic n salt from a shop bought tub of the pre-mixed stuff then he's never learnt to cook at a basic level, achieving crispy skin states in an air fryer is not

science.
I did monitor the change in energy use when we bought one of these things a few weeks ago. I didn't get as big an energy saving as reported in that article, but it was a worthwhile reduction, all the same. My best guess from the measurements is that the air fryer (what we have is really a combination mini-oven) uses around 60% or so of the energy of our built in fan oven.
The baked potato observation was interesting, as we haven't found any difference at all. The technique we use for baked potatoes is to first partially cook them in the microwave (this heats down to the centre of them well) and then finish them off in the oven, rubbing the skin with butter to help them crisp up. The mini-oven does a better job of finishing baked potatoes off in air fryer mode, and is a lot quicker. I need to try an energy use comparison between this hybrid cooking method and just using the fan oven or air fryer alone.
Overall I think we're using maybe 500Wh to 1kWh per day less since we got the mini-oven. Hard to be sure, given the degree of variability from day to day, but that seems to be in the right ball park. There are just two of us, though, so we don't often cook large meals. For us the saving in cost is modest, maybe ten to twenty pence a day, as we're only saving off-peak electricity, but for those without battery systems the saving could be around double that, so more worthwhile.
