This is an interesting presentation on peak oil. My predicition is that this issue will end suburia as we know it. I am old enough that I will not see this transition, but it will be a major issue for my grandchildren. In the mean time, energy prices will have a constant upward pressure as more people around the world get richer and richer. I do not think there will be shortages as coal is somewhat abundant. The chart on the right is one scenario for peak oil.
