that peak demand has come and gone in the OECD world, likely sometime in 2005. This is not, however, in agreement with peak oil, which is more on the extraction and production side. CERA continues to believe that there is plenty of oil under ground. In predicting peak demand in developed countries, CERA states that long-term demand is softening as a result of demographic and socioeconomic changes in developed countries (such as the aging of OECD populations), improved transportation efficiency, and encroachment by substitutes such as biofuels and natural gas.
