According to the German Energy Watch Group, world oil production peaked in 2006, far earlier than expected. The nonprofit's scientists, working independently of government and industry, analyzed oil production figures and predicted it would fall by 7 percent a year, dropping to half of current levels by 2030. The report also predicts falls in gas, coal and uranium production, and warns that supply shortages could cause meltdowns in human society.
