Michael, new houses get plumbed with plastic. I’m not saying that’s a good thing, plastic pollution is another major problem, but it does cut down the demand for copper. And as Lapsed Agnostic has pointed out, a vast quantity of copper can be salvaged as plumbing systems get replaced.
Given the comments on piping I indulged my curiosity about the advantages and disadvantages of copper and plastic plumbing.

I’ve looked at a few links this one is a good overall summary.
I guess if copper is needed more for other things then plastic piping is a good substitute.For you Michael, Radical electric motor runs without metal coils. Still in a lab and with all sorts of downsides but maybe someday we’ll have alternatives to copper (or metal) conductors.
For you Fat John DARPA sets new records for sending power wirelessly.
Very inefficient but that’s where we’re at.ET, the company you just linked to is right next to my nearest railway station! Come to Chelmsford for good, clear technical advice; we’re a load of geeks here.
Though we can’t get apostrophe’s right :-/
Lol.Clark, I was gonna apologise to you that I didn’t have a specific link for you. I’m a kind of (drunk right now) geek, I might fit in.
ET, your link is quite specific enough. I had noticed your geekery, and I congratulate you on it.
Adam: “What’s the difference between a geek and a nerd?”
Bill: “I don’t know; what is the difference between a geek and a nerd?”
Adam: “Ah, a geek would know.”A woman friend of mine, purchased a new small semi-detached house,the electricity came up from the ground adjacent to the wall between the two properties, we assume this was the cheapest was to do it for the joined two properties.
She then bought a second hand EV.
She had a terminal put on the front of her house, so she could charge her electric car.
They had to use very heavy cable, going from the party wall, along the wall of her living room, across the outside of the rear, then down the outside, of the side, then on to the front of her house.
So, four years ago, this cost her almost four thousand pounds.
Quite a lot of Copper.
I think she said there were three types of installations, depending how much current you draw.
She chose the middle priced one.
I guess 100 amps.
I might be wrong.
Probably a more expensive new house, might already be fitted with with a car charger/
Another woman friend of mine, just had solar fitted to her two bed semi, with a battery pack and electrical/electronic stuff, again not cheap.
If the New Labour Government want us to go all electric, I am assuming a modern house will have a lot more Copper than an older house.
If you build a whole new estate and each house was to be fitted with heat pump, solar roof and batteries and fast EV charger point, that estate will need much heavier wiring than an estate first fitted with electricity in the 1920’s – 1930’s.
What I am getting at, is that we will need more Copper not less Copper.
The rest of the globe who barely use electricity now, will expect electricity in the near future.
As the resourse of Copper becomes harder to obtain, the price of Copper will rise.
