Why? I didn't start using more energy elsewhere when I switched to an EV or electric lawn maintenance tools. You think companies and people are using exactly as much power as available (or they can afford)?
The crux of Jevon's paradox is that you’re lowering the cost of revenue below the sale price.
If I can generate $10 a sale then I’ll do no sales if it costs me $11 . If gas drops from $4 to $2 then I’ll do as many sales as I can as $9 is less than $10.
Pre-industrial revolution most people in my country own enough clothing for everyday and then maybe some extra stuff for "best" appearance like church. Making a shirt requires hours of labour from skilled workers. The machines eliminate one of those jobs ("hand" weaving, using a loom that you operate at human scale, replaced by enormous machine looms which produce much more fabric and much faster with far less human labour) and streamline others so that the price of a garment collapses. So people buy a lot more garments. You probably own enough clothes that you can wear different clothes each day for at least a week, likely more, and you think nothing of it.
Most people won't buy so many clothes that they can't even wear items once, but many get pretty close, and so worldwide we produce hugely more clothing per person than before the textile mills were first built.
Just took my house onto off-grid solar, yet my energy consumption now exceeds when I was on utility grid power.
Naturally we ration things when they're expensive. But now I don't feel the need to turn off the lights or appliances when I leave my home, and my EV driving has gone up knowing that "fuel" is essentially free from here on out. And to soak up excess solar, I run multiple computers and servers 24/7 with reckless abandon.
"Free" fuel for you just pushes the externalities elsewhere.
I was brought up to "save energy ". Lights switched off when not in thevroom, that sort of thing.
Now I gave solar on the roof. There's an excess production capability, so now, during most days it doesn't matter if stuff is on or off. That especially applies to AC which I'll happily turn on on hot summer days. In effect I use more "because it's there to be used".
My EV is coming soon and given I can charge it on solar I plan to do a lot more day-trips-out over weekends etc.
So you're right, availability and affordability- but electrifying is great (for me) for both those things.
