According to Figure 1 of the CERA report, a huge part of the "increse" in sales are from "Uncoventional Oil." The Peak Oil theory does address this classification of oil. It is hard to locate, expensive, and very damaging to the environment to extract (just look up tar sands in google or wikipedia). The peak oil theory states that most of the "Conventional" oil has been found, and production will decrease over time. CERA's report simply claims it will happen later, but even their data shows a peak in oil production. Ther key is that there is a limited supply of oil, but no one can agree to when we will reach peak production. That is because no one really knows how much oil is left in the ground, and oil consumption is only going up.
