Peak oil. We’ve all heard about it. The late great Captain Crude got kicked off The Oil Drum for writing about it, albeit in a soggy way reminiscent of Joe Hazelwood’s piloting style. Gulf-of-Mexico hurricanes sometimes shut down or mess up the oil importing / refining / distribution infrastructure here in the United States, resulting in a fleeting, evanescent awareness here that perhaps the continued flow of oil isn’t as guaranteed as we’d like to think it is. A month or two after the troubles go away, American yeasties resume their habits of living large on the sugar that keeps flowing into their petri dish, secure in the knowledge that “other people” are taking care of any potential problems.
