Earth's Copper Supply Inadequate For Development? 838
ScentCone writes "Pennies, pipes, untold miles of CAT5 - they tie up a lot of copper. Unlike abundant iron and aluminum, copper is relatively scarce. 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. Canada, Mexico and the US average 170kg of copper use per person, and the most generous estimates suggest that only 1.6 billion unused metric tons exist. More reclamation and use of fiber, wireless, and PVC helps - but won't be enough to cover the billions of people who don't yet live in highly wired/mechanized societies."

they actually produce 15% of the countries copper annually. But I have been hearing that the mine is basically tapped (at least the current mine) And that they will be starting a new mine a little futher back in the Oquirr mountains in order the meet the needs of the country.
Interestingly enough, they also produce a significant portion of the countries Uranium, Iron, and other precious metals. But i can see how we could eventually run out of resources. Hence them being natural resources. Luckily, since copper is a natually occuring element, it should be more abundant at deeper sub-terrain.

Aluminum (Score:3, Interesting)
If copper becomes expensive, developing countries will just use aluminum. The biggest problem with aluminum wiring is joining it to copper; this is the only thing that really inhibited aluminum wiring in this country, where there was already a ton of copper wiring everywhere. Places starting from scratch won't have that problem so much. Long-distance transmission lines will likely be copper for a long time due to the lower resistance. (Gold, BTW, is a worse conductor than copper, and is quite comparable with aluminum. Silver is slightly better than copper, if you're willing to pay.) There will be more and more transmission lines being built with superconductors [supercables.com], though!
Of course, the incredible energy requirements of aluminum production yields its own set of headaches. But if we don't solve that problem, the wiring dilemma will be moot anyhow.

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.

I agree with you on Copper. However, I think you may be off on Oil. I have read that it's been 2 years since any new major Oil fields have been discovered. For the past 50 years we have found at least 1 new Oil field a year. The cost of Oil has also gone from $30 a barrel to $66 a barrel. I have also read that the north sea Oils production peaked 3 years ago and is on it's decline. We will never completely run out of Oil. however, we will run out of enough Oil in the next 75-100 years to make life interesting if there are no alternatives.

While we're at it, get rid of the dollar bill. Most people don't realise this, but the government could save over $400 million per year by elliminating it. There's several reasons for this but the big one is that dollar bills have a short life span (about 13 months) and people would switch to dollar coins ($2 useage might increase a little but probably not much). Paper money should only be printed in denominations that have actualy buying power. You can't even buy a cup of coffee anymore with a dollar bill.

Er, no. Nobody in oil geology thinks that. The most optimistic projections are that peak oil is about 25 year away. The pessimistic projection is that the peak was reached last year. The consensus is that the peak is somewhere between now and 2015.
Classical economists tend to mis-analyze oil. The price is related to cost of extraction, which is low. Until demand exceeds supply. But throwing more money at search and extraction doesn't yield much more supply. Oil discovery rates peaked in the 1960s. Economists tend to assume that if demand exceeds supply, new sources will emerge. But the geology doesn't work that way. Four specific geological conditions have to be present for an oil field, and almost all the areas on the planet that meet those conditions have been explored. About 90% of the world's oil lies in 30 known major petroleum systems.
Right now, we're just about at the point where demand will exceed capacity. Demand is still climbing, mostly due to China's industrialization. All the OPEC countries except Saudi Arabia are producing flat-out. (Kuwait, incidentally, peaked a few months ago. The US peaked in 1970.) There's general suspicion that the world's biggest oil field, Gawar in Saudi Arabia, is at peak production.
The decisive moment will be when the Gawar field peaks. That will probably be the peak of worldwide oil production. Some people think Gawar has already peaked.

Recycling of our old copper products is really the way to look here. Not only does it lessen the drain of our limited copper supply, which is good for everyone, but it lessens the impact on the environment of copper strip mining which releases unthinkable amounts of tainted water into the oceans around South America and New Zealand every year. Not only that, but it can be offered at a lower price because high purity copper is much easier to extract from bundles of wires made from high purity copper than from piles of ore from the ground.

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 [google.com] 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)...

Copper pipes and whatnot are slowly but surely being replaced by pvc, copper is now only used in small pieces of pipe or where there's going to be a lot of heat going through the pipes. PVC is used for just about everything else.
Cabling in the next decade or two will be replaced by fibre, if copper prices rise, many companies will find it profitable to just go all out on fibre and rip their copper lines off the poles, out of the ground, and out of the walls. cable tv, IPTV, broadband will all do this eventually, plus fibre's cost to maintain is noticeably lower than copper's. you dont need to repeat signals as often, better transmission, etc.
Cabling in computers, minus electrical uses, will soon be fibre, at least for hard drives and cdrom drives, as it will be the best way to send data, sound cables may eventually be fibre as well, digital does have its perks in that respect.
We do have the means to make plastic (which lower end fibre can be made from), even when petroleum is gone, we still have methods of making oil for those purposes. Then there's glass.
Then the last resort too are landfills, which are the goldmines of the future. all the organics will be broken down, there will be a huge abundance of metals in them, and gasses that can be used for energy.

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.
