The original study abstract is a little more clear. The main concern is grid storage batteries and EV batteries.

Given that the sharp increase in copper demand is primarily driven by batteries, the extra copper needs for electrification can be significantly reduced if the need for electrical storage is minimized. This can be achieved by generating electricity through a mix of nuclear, wind, and photovoltaics; managing power generation with backup electric plants fueled by methane from abundant resources of natural gas; and transitioning to a predominantly hybrid transportation fleet rather than fully electric vehicles.

Your argument against the article that talks about copper usage is founded on incomplete knowledge of where copper is actually used?

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.

Aluminium is very commonly used. It isn't near as good a conductor as copper, but you can easilly use more toeget results and in most cases that works fine.

The reason we stopped using aluminimun more is it is relly tricky. when you tighten a screw the al deforms over time and so you don't get a lasting connection. Al also corrodes to a non conductive state. Many house fires were traced to al wiring in just the few years it was common. We can mitigate all the above issuses but it takes care and so copper is preferred despite al being much cheaper.

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.

1. The article is shit, the study is about copper used for 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.

2. 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.

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.

What I mean is that the bulk of current copper wiring goes towards distribution and consumption, not generation.

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.

2. 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.

Have they tried pulling it out of the walls of abandoned buildings? There's a lot left in there that no one uses anymore. /s

hey it has been 15 years

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.

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

Thousands of fires disagree

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.
