    What is this publication and who finances it because this section is incredibly sus:

    Copper use is not carved in stone. Hybrid cars, which pair small batteries with gasoline engines, need far less of the metal than fully electric vehicles.

    Power grids that mix nuclear, wind, solar, and a pinch of natural-gas backup can slice the copper bill dramatically compared with battery-heavy systems.

    “First of all, users can fact-check the study, but also they can change the study parameters and evaluate how much copper is required if we have an electric grid that is 20% nuclear, 40% methane, 20% wind, and 20% hydroelectric, for example,” Simon said. “They can make those changes and see what the copper demand will be.”

    Like you think we can transition to an increasingly electrified world, where all power comes from electric utility lines, and you think our copper usage will be … just in renewable power plants?

    This reads like straight fossil fuel propaganda. In an electrified future the majority of copper use comes from distribution lines and products that use electricity not the type of power plants generating electricity.

      I’m not defending the article, but I think most overhead power lines are aluminium, which is probably good as it’s abundant compared to copper.

        The problem with aluminum is that it gets REALLY hot when current is run through it. It used to be ised to wire homes, but is now banned because it wasn’t safe.

      1. The article is shit, the study is about copper used reducing fossil-fuel power generation. It is basing the projected use of copper on windmills and especially large batteries.

      2. Those high-powered and long distance power lines are made aluminium and steel.

        1. Distribution doesn’t just include long distance distribution. It includes all the wiring between transformers and houses and all the internal wiring of the house and all the devices inside etc.

      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.

      • frezik@midwest.social ⁨6⁩ ⁨days⁩ ago

        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.

        Aluminium is actually a better conductor than copper when you judge it by mass, not volume. I think also by tensile strength.

        In any case there’s a reason that large overland wires aren’t copper, but steel-cladded aluminium. Copper will always have its applications but so does gold and yet we’re not running out of gold to plate connections with.

        In cases like windings requiring more volume is actually an issue, in the case of PCBs… no, despite Apple’s insistence, it’s actually fine to have a phone that’s 0.2mm thicker.

      You’re wrong in terms of long distance power lines being mostly copper, but this does seem a lot like fossil fuel propaganda.

      Motors, generators, and transformers can be built using aluminium; they’re just a bit bulkier and less efficient. Very common practice.

      It looks like CCA might be making its way back into house wiring in the near future, with much lower risks than the 70s aluminium scare.

      The big thing is that batteries really should be a last resort, behind demand response (using power when it is available, rather than storing it for later), long distance transmission, and public transport instead of private vehicles.

        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.

      it sounded like they were trying to say battery grid storage is going to be the main problem here:

      After the introduction of smartphones, wind turbines, and high-capacity batteries, copper’s role has grown from important to indispensable.

      except the article they linked is about lithium-CO2 batteries and does not mention copper at all.

      Even if we really do need to reduce grid storage to save copper, we can do that with more baseline nuclear power, no need to keep involving fossil fuels.

    This smells a little funny, as others have suggested. I read an article a while ago that suggested that we’re not running out of raw materials; we’re thinking about the problem wrong:

    Chachra proposes that we could – we must – treat material as scarce, and that one way to do this is to recognize that energy is not. We can trade energy for material, opting for more energy intensive manufacturing processes that make materials easier to recover when the good reaches its end of life. We can also opt for energy intensive material recovery processes. If we put our focus on designing objects that decompose gracefully back into the material stream, we can build the energy infrastructure to make energy truly abundant and truly clean.

    This is all outlined in the book How Infrastructure Works from Deb Chachra.

    This all suggests that we keep producing, wasting and manufacturing things infinitely without ever recycling, reusing or re purposing everything that we are mining out of the ground. The article notes that this includes recycling but only at the rate we have now.

    If we keep running our world the way we are now for the next hundred yes … than yes, we are going to run out of everything because we live in an absolutely wasteful society that only runs in a way to produce things designed with planned obsolescence to break down in a short amount of time so that we can produce more junk to sell and drive a stupid economy to make a small group of idiots even more wealthy. The whole system is designed to run on making infinite money by producing infinite junk that doesn’t last long.

    Yes at the rate we are going and the way we are producing things and the way we shape our economy and the way we base our manufacturing … we are definitely going to run out of everything.

    We can change our economy and the way we produce and manufacture things - and get rid of this stupid structure of society of just endlessly making money for a small group of morons … or we can keep doing things the way we are now until we run off a cliff and destroy everything and drive our species into extinction.

    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.

        They’ll 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!”

      That alternative material is aluminum. It’s like a top four abundance material in the crust. It’s just super fucking hard to refine from minerals that don’t like to give it up without oodles of energy. Like, turn minerals into plasma levels of energy. So the irony is, to grow our energy economy past the need for copper, we will first need to grow our energy economy.

      Should fusion ever actually meet its promise, then this is one of the likely things we could do with this level of energy.

      If we ever become a spacefaring civilization, it’ll almost certainly be necessary during the colonization of other planets/moons/asteroids, since the geological processes that concentrate copper on the earth are not present in those places. Whereas aluminum is plentiful any place rocky.

        Aluminum expands under electrical loads and the wires become loose. Loose wires are a fire hazard.

        The real solution is steel wire with a copper coating. Electricity flows on the outer region of wires anyhow.

        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. _

        Its possible to just coat the surface if that’s the effect needed. I was so happy a year ago that I had found copper Ethernet wire. However upon inspection recently the wire is basically aluminum coated in copper. Usually, platers will first clean the surface and then electro less coat nickel on aluminum. Then you can coat other things like copper. Aluminum forms an oxide almost instantly in normal atmosphere so its difficult to coat with anything. But electroless nickel works very well after an HCl bath or a nitric bath.
