asteroid mining

only residential wiring uses copper, everything from 350kV down to 400V lines is aluminum, and even in houses aluminum can be used too
aluminum can be used too

From old electrical connections that weren't designed for the different rates of expansion of aluminum and copper. Today, most of them are.

In a lot of cases you can also use Aluminum instead of copper. You need thicker wires and it's less flexible, but it's doable and cheaper. Some old electric motors from the eastern block used aluminium coils for that matter, because copper was much more expensive there.
The US is allergic to it, but needs to get over it.
Aluminum wire was tried in the 1970s due to a spike in copper prices. The problem was that they just tried to swap it right in. Aluminum and copper have different rates of expansion. Over time, that would slowly loosen the connectors, and the wires would pop right out and cause a fire.
You can design connectors to handle both, and you'll see many electrical things today specify that they're good for aluminum or copper wire. It still has a bad reputation among electricians; they haven't unlearned the problem yet.
Now, one place it's more of a problem is in things like transformer windings. There are kilometers of wiring in any of them, so the higher resistance of aluminum is a problem.

There could be two ways to address this problem. One is asteroid mining, which has the potential to be extremely lucrative because there are lots of asteroids with huge metal deposits.
Another is discovering new conductors. There's been progress in developing conductive plastics.

Good think we can use aluminum and copper then...

Perhaps it’s time to start researching alternative materials.
Plenty of metals floating around in space. Just need to go and get them.
Only need to capture one decent sized metalliferous asteroid from a near earth orbit and we'd be set for a century or two.
Things like platinum notwithstanding, It will almost always be more expensive to go get things in space than on earth.
Hell, even on earth it is often too expensive to get metals like iron if there isn't rail or a port nearby. Imagine having to fly iron ingots around and the associated aviation fuel cost. Whatever crazy fuel bill you're imagining, multiply by a hundred or more if you're imagining getting it from space.
No, all of those metals in space are best used to build some future version of our civilization _in situ. _

this was before we figured out that you can use stranded aluminum wire and it's fine this way
that, or copper clad aluminum

Meth-heads?

Well couldn't we, like, share it? The average joe in america is consuming 100 times more than an indian
But that would be unfair to the average Joe! And think about the billionaires; how would they survive if everything was shared? /s

How much old copper piping is still out there that could be replaced by other materials to recover the copper? I'm sure there are other common obsolete applications. The nice thing about metals is that we already have a pretty robust recycling chain in place for them. That plus the remaining supply plus aluminium plus other replacements plus careful design to minimize the use of copper where it's absolutely necessary might be enough to carry us through.

Its not just electricians, its got a stigma that seems really hard to overcome without some sort of education campaign. People wont buy a place that has aluminum wires.

Is it? As far as I know you can use a larger diameter wire to get the same resistance as copper, if your device has enough space for bigger coils.

The poor will have scavenged the abandoned buildings in built-up areas, yes. Still-occupied buildings and those in smaller towns with no easy access to a scrapyard are more likely to be intact. So it's more likely to be a case of "these are no longer to code, they are not grandfathered, you have a two-year grace period to switch them out" (staggered geographically or by building classification to avoid a run on plastic pipes) plus "road trip!"
We might also end up mining older dumps for stuff discarded when copper was cheaper.

This was my first thought, we aren't going to develop the whole world. That's not how this works. Who said that was a goal of... well ... anyone's?
That's a rhetorical question. Frfr tho, does that remind me work on your instance only, or what's the deal with that?
Just banking on some bot figuring out how to do this within the next 15 years.
There used to be a bot like this on that site that was run by that troubled young man who decided to focus exclusively on monetization to selfishly help fund lawsuits related to multiple instances of trespassing on farms and being found pants down fucking chickens.

Abolish copper coins. Job done

What I mean is that the bulk of current copper wiring goes towards distribution and consumption, not generation.
Yes, but big batteries everywhere is going to effect that if there's copper in lithium batteries, and apparently there is.
This isn't a big thing. This is a constant thing in every system. It's the push and pull between efficiency and resiliency. More storage capacity is less efficient when things are going well, but is more resilient and adaptable when they're not.
Excess storage capacity, sure.
But inflating the base battery capacity to cover people having showers at 5pm because it's easier than storage water heaters and time/remote controls is stupid. You can reduce the base need for batteries by reducing the need for electricity in the first place and reducing the use of vehicles that need to carry batteries in place of e.g. overhead catenary.

Largely done already, as I understand it. Most use zinc now.
