Robert Hurst, author of the popular Art of Cycling book, added a footnote in his second edition about a troubling societal dilemma looming in the near future: the growing inability of of global energy supply to meet global energy supply. In his latest blog entry, Robert takes a look at the current situation, taking input from industry analysts and reviewing what the mass media is now saying about the specter of Peak Oil.
If you haven't yet heard of Peak Oil, Robert's essay is a good introduction. You can read it here on his blog. He also points to a couple of my daily reads: The Oil Drum and oil engineer Robert Rapier's R Squared Blog.
