but......i thought there must be larger losses in the wires, they are made of steel!
I eat lunch once per week with a senior manager of the local electric utility. He says they use a wire made of a steel core and aluminum outer as the primary conductor. Only the service entrance drop is insulated.

The neighborhood feed is usually 900-1000 volts. I find amazing that 20 or so homes can have 200A service from that one wire.

More likely what will happen is that as we die off, those who follow us will become used to things which we disdain. If you had told me 40 or even 30 years ago that I wouldn’t eat beef on a regular basis I would have looked at you like you had 3 arms. Yet now for health reasons I eat lean pork, chicken, or plant based meals. I do allow myself beef about once a month, because let’s face it; nothing’s quite like a good steak or well prepared hamburger. 😛

I think they should standardize on EV battery packs sort of like they do with traditional battery group sizes and have the batteries insert from below. Instead of all these quick charge stations, pull into a converted oil change type of place or gas station and have them swap battery packs from below for a fee and be off on your way. This would work along the freeway as well. Normal charging would stay the same.

The idea that every car brand and model has their own unique battery packs and technology is going to be a recycling nightmare.
