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.
