Earth's Copper Supply Inadequate For Development?

But it's vital to electricity generation/transmission, plumbing, and other uses central to a modern standard of living. Scientific American is providing a quick overview of the situation. They report the conclusion that there simply isn't enough available.

    When I was in the supply installation side of IT consulting, the company that I co-owned ran network cables (and phone cord and work with electrical contractors that laid electrical wire). Copper price could KILL us if we bid a project and then the price of copper went up. In fact, on the largest projects we actually took advantage of futures-style market provisions to pre-buy our copper at a set price (even if it fell, we still paid a certain price).

    To say that copper is scarce is not really accurate -- the price of copper has gone up but not in the way you'd expect if a needed item was about to run out. I blog (and publish a print newsletter) about gold -- I do about 90% of my research trying to find the manipulators in the gold market. One of the "worst" manipulators is the mining industry itself, but I believe hiding trade facts is very important for a free market. If copper was truly disappearing, you'd see the market react by the price hyperinflating, not just steadily growing. Mining companies spend 10-15 years just opening a mine. If they knew they were running out, they wouldn't sell it so cheaply.

    I believe the steady growth in the price of copper is more of an effect of fiat currency inflation causing all consumer goods and salaries to go up (basically devaluing everyone's labor even if they feel they're earning more). When copper goes up 1000% in a week, there will be a problem. 1% fluctuations is nothing.

    Just as I don't believe we're anywhere near to running out of oil in the next 1000 years, I don't believe we'll be running out of copper. I study 5-10 mining reports a day and all I see is more and more oil, gold, carbon and copper being found. As we innovate and are able to drill deeper and deeper, we're finding that MOST of what geophysicists warned us about 10 years ago isn't true -- we keep finding more to consumer, not less. I think we will be able to say the same thing 10 years from now and 100 years from now -- we're amazed and what we're finding as we dig deeper.

    All these "fear the scarcity" news reports on vital materials are bunk -- you'll know when there is a shortage when the price skyrockets (supply and demand is very hard to manipulate in the long run). And when the price skyrockets, it will give innovators reason to find new ways to recycle more efficiently, dig deeper or find other ways to provide the same service with a different product.

    The day that copper is gone for good is the day that we take clay out of the ground and find a way to offer room temperature superconductivity. Serendipity doesn't end, and higher copper prices give innovators more reason to find new solutions to yesterday's problems. One of the reasons I formulated my anarcho-capitalist belief system is based on finding that supply and demand really does set prices in the long haul, even if government and industry tries to manipulate prices in the short run.

      Really, though, I don't understand the big panic. So copper prices rise as the easily minable deposits get exhausted - and? There are replacement materials. There's silver for when you need great conductivity (better than copper), and there's aluminum for when you don't (and you can tolerate metal fatigue). There are many other metals that could be used in between the two, and many of the metals that are common in the ground but are hard to refine show signs of significant price reduction in the future.

      So the length of runs of wire that you can use become shorter. So it uses a little more power. So bandwidth capability decreases. Or, so people pay a higher price. Copper will never disappear; the shortage just means that people will have to turn to mining less rich/harder to refine deposits.

  19. Re:Pennies by linuxwrangler · · Score: 4, Interesting

    Maybe a lot of /.ers are too young to remember the great penny hoarding of a few decades back. At the time, copper reached a price that a penny contained more than a penny worth of copper so people started hoarding them and melting them down. There was a shortage of pennies for change and some shopkeepers resorted to rounding to the nickel, others used candy for change.

    The composition of the penny was changed to use copper plate. I seem to recall that the feds outlawed melting of pennies as well but that was a long time ago.

    Anyway, I agree that eliminating the penny is long overdue but the feds don't seem to want to make that embarrasing admission that inflation exists and money is becoming worthless. Back in the day when Nixon imposed the (ill-considered and ineffective) wage and price freeze it was in response to runaway inflation at ~3%. Nowdays we call that rate "controlled". Hell, during the reign of the great inflation-controlling Greenspan, the dollar lost about half of its purchasing power. Time to drop the charade.

    Transmission lines are already often made with aluminum.

    The problem with aluminum for transmission lines isn't so much the conductivity, but the mechanical strength. Aluminum is paired up with steel or some composite to solve that issue.

    I thought I'd point out another resource that won't be replaced, either, but that doesn't get mentioned very often: Helium.

    I wasn't partiuclarly aware that this was a consumable resource until recently, but it is. Every cubic foot of helium gas that's released up into the atmosphere is basically lost forever -- it's so light that it just keeps going up and up, and eventually escapes our atmosphere.

    Although it's not as important to us as a civilization as copper, and will probably take longer to become scarce, it's not something that's partiularly easy to get. Right now we get most of our supply from the natural gas industry -- helium is present in natural gas but doesn't burn, and if not extracted from the gas prior to use just goes out the tailpipe. There are (or were) government-backed programs to extract and store the He prior to use of the natural gas, but I'm not sure if that's still going on.

    We use an increasing amount of Helium in its liquid form as cooling, partiularly for MRI machines. I can only see this usage getting bigger in the future; plus, liquid He is one of the only ways to reliably get objects down to ultra-cold temperatures, which might become very important in the future. (Superconducting computers?) The point is that we really haven't exploited Helium very far, and yet we're 'burning' through it fairly quickly, along with the natural gas supply.

    It's just another thing that when it's gone, it's gone. It may seem frivolous now, but when you consider the difficulty of synthesizing a hydrocarbon chain, it's not partiularly tough. Make me a mole of helium atoms cheaply on an industrial scale? Now that's difficult.

  23. The sad thing is... by cr0sh · · Score: 3, Interesting
    The sad thing is that much of this "used up" copper is sitting in landfills (current and former). It's not just copper, either. There is a ton of material in our landfills, thanks to the environment (buried in dirt, sealed from air and the water table, lack of oxygen), doesn't break down over time, whether the material is organic or not.

    I tend to wonder if some day, perhaps sooner than we think, it will be profitable to mine these landfills (many currently golf courses and home sites!) for that "wasted" material, for recycling purposes. Furthermore, I think about the tons of organic material (yard and landscaping waste, mostly) which is in our landfills (and more going in every day) which could be reclaimed, recycled, and then fed into thermodepolymerization plants tuned for the feedstock, allowing us to gain fuels and other useful materials from stuff that is just being thrown away.

    Think about all the organic material from New Orleans which was simply bulldozed into landfills? Could that material have been run through a TDP process and used to offset, in whatever percentage, the fuel shortages caused by Katrina? Why do we throw this stuff away, when we can use it for other purposes?

    Fortunately, most metals are recycled already, but there is still a lot of useful stuff in our landfills (including a lot of metals), just waiting for the day to be used again (unfortunately, in order to get at the stuff with any measure of safety, these landfills would have to be strip-mined)...

  24. Susan B's were rejected by people by blueZ3 · · Score: 3, Interesting

    because of the similarity (in size, color, and the scored edges) to a quarter. When they were more common (close to when they were first issued) I was the recipient of Susan B's instead of quarters as change on several occasions. If I didn't look closely, I didn't notice and someone's cash drawer was down $.75 at the end of the day. No one wanted to deal with them, because they weren't easy to distinguish from quarters and in a fast-pased retail environment, could easily be mistaken for them.

    When the Sacajawea dollars were designed, they were made larger, a different color, and the edges were smoothed precisely to help avoid this confusion. This helped, some.

    However, in the long run, would you rather have nine 3x6 folded sheets of paper in your pocket, or nine large coins? Most people prefer the weight and flexibility of paper.

  25. what puzzles me by khallow · · Score: 3, Interesting
    Why is have 240 kg of copper consumption per capita per year considered a "developed world" lifestyle? What makes a certain level of consumption of materials necessary for a certain quality of life? Remember that until the late 90's (ie, suspiciously near 1999), copper was extremely cheap. In this PDF report the US Geographic Survey indicates that copper sold in the years 1998-2002 for the cheapest it ever had in the past century (when adjusted for inflation). If something is cheap, then it will be consumed in quantity.

    One of the semantic tricks pulled by the Science News story and perhaps by the original authors is to term consumption a "need". In other words, just because the world is consuming copper at unusually high rates due to its low cost, this consumption is "needed". My take is that once copper rises, the "need" will dissipate.

    And that brings me to my final point. Why is this a problem? If copper becomes scarce then its price will rise and people will comsume less of it. My point here is that this problem is already solved. The economy will adjust for it naturally.
