Earth's Copper Supply Inadequate For Development?

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."

      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.

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, though!

    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.
