I agree with your core idea, lower energy requirements are coming. Heck, ICE vehicles turn about 70% of their energy into heat - electrification is going to do a lot to help reduce our energy needs.

But the issue is a lot of the slightly more pessimistic smart money is betting on us going from a 20 TwH society to a 5TwH society. That is a sizable drop that efficiency alone cannot account for. That will also lead to a societal change that could potentially be for the better.

To go Y contaminator on this, with fossil fuels we have funded a lot of companies but as we more to the more sustainable long terms energy flows we will have to find out what can genuinely last. Like warren buffet said "When the tide goes out, you figure out who is skinny dipping".

On a deeper level, in a sort of Yin and Yang kind of way; the good news if we don't manage to keep up our consumption is that it means the rest of the world will get some relief from the tyranny of man. Is this good or bad? That dependents on the ethics of the individual.

I think I heard something like 30% of all energy production gets turned into waste heat somewhere in the grid? Home supplies in the US are 120VAC60, you have high-voltage transmission lines at all sorts of voltages, and then most of our electronics have to rectify that to DC. I have to wonder how much of that loss goes away when the majority of household power is consumed in the same building it is produced.
