"The world needs copper. Humans were shaping it into spearpoints as long as 9,500 years ago. But demand really started soaring at the turn of the last century, after we discovered how well copper conducts electricity. Now we need it more than ever: It’s essential to transitioning off fossil fuels and toward renewable sources of electricity. “The shift to a clean energy system is set to drive a huge increase in the requirements” for copper, the International Energy Agency reported last year."

So it seems electric cars may have to find an alternative source of energy if the electricity network can't handle the load. Even hydrogen cells have their risks...

Ah, this has reached the media. Yes, just another glitch one come across
when one thinks the idea through.

Even at present day costs one has to make sure power cables are buried
before you leave the site. 66KV need guards over night.

This is going to be the great glitch, and with fast charging it will not be

BTW silver conducts heat and electricty better than copper, so all good. ;-)

Aluminium is not too shabby either, provided it is kept cool. But not quite as
good as gold, perhaps we should stick with silver which is cheaper than gold.
Joking apart, this issue is not new, merely been ignored. It is a government
(of all stripes and all countries) problem, the industries involved have no
imperative to fix it.
