This is an excellent video which explains Hubbert's peak theory when applied to other natural resources besides oil - peak uranium, peak copper, peak coal, etc. Those who argue that peak oilers habour unfounded fears about the future because we have hundreds of years of coal and uranium deposits that we can rely on often overlook the principle of net energy (EROEI/EROI) and diminishing ore grades. Chris Martenson has done a superb job of explaining in his videos the current crises and connection between the economy, the environment and energy. I encourage everyone to visit his website at http://www.chrismartenson.com/crashcourse and register (it's free) to view his videos in high resolution.
