Since the gas thread has attracted immense interest, I thought I'd start one on a related subject: Peak Oil. The basic tenets of Peak Oil are pretty simple. Being a finite substance, sooner or later production of oil will reach a peak, after which supply will never satisfy demand. The consequences of this peak are enormous, since civilization is based upon the cheap, plentiful bounty of fossil fuels. A geologist, M. King Hubbert, predicted in the mid-1950s that US production would peak in the late 1960s/early 1970s. He was ridiculed for this announcement, but US production did, in fact, peak in 1970 and even the discoveries in Alaska were not been enough to stop the decline. On the worldwide scale, production of sweet, light crude (the good stuff) peaked in 2005. Exacerbating the problem is the fact that all the easy to find and extract oil has already been produced, leaving the hard to get at and expensive to produce stuff. Want to know what's really going on with the price of gas? Look into Peak Oil.
