Reuters reports today that the United States gasoline supply has hit a 2-year low. While the article explains a dip in supply often happens at the end of the summer, long-term fossil fuel availability is the subject of much speculation. J.H. Kunstler is one such speculator and his recent book, The Long Emergency, envisions a future without petroleum-based transportation (here is a teaser of his dystopian vision).
Contra Kunstler, Robert Bruegmann of the University of Illinois argues in his book Sprawl: A Compact History that the benefits to a society from petroleum use greatly outweigh the risks. It is also argued that concerns regarding petroleum use are exaggerated. Kunstler's rebuttal can be found here.
