The IEA's 2008 World Energy Outlook brewed a particular
furore among the resource realist community. With petroleum prices on the run and all the ingredients of economic recession already in the pot, this report granted the world with a cornucopian vision of fossil fuels that was hard to square with reality. During the months that followed TheOilDrum thoroughly took on this report with multiple articles from various contributors.
I was particularly intrigued with the CO2 emissions projections in this report. In the standard scenario atmospheric CO2 concentration was projected to reach 1 000 parts per million (ppm) by the end of the century, a near tripling in 100 years. I set out to construct
a CO2 emission scenario based on technical fossil fuel extraction projections, and failed to get even to 500 ppm. However, the most fascinating result of that exercise was the relative imminence of a global CO2 emissions peak. Coal represents the largest underground stock of energy and the uncertainty on its ultimate size is high. Notwithstanding, following on the same growth path, a CO2 emissions peak by 2025 was only in reach to the most optimistic Coal extraction scenario. Such is the power of exponential growth.
News of recent days remind again this reality. "Coal bust" is an expression employed to characterise a market that might not be merely conjunctural.
