There is a Google video on interview with Nate Hagens (The Oil Drum guy) about peak oil. There are some interesting things in there:
There are evolutionary reasons for believing that present is better than future until we see some evidence. He says it has something to do with economic theory of discount rate.
Bio fuels have incredibly low EROI (Energy Return on Investment) – 3-1 as compared to fossil fuels – which is somewhere from 30-1 to 17-1.
Some statistics: Each American uses 57 barrels of oil per year. And with an energy equivalent to 1 barrel of oil, a person can lift bricks costing 12.5 years of physical labour. It means approximately 700 years of physical labour behind each person per year. 🙂
