Olie en kolen (15 mei 2007)
Ik zet hier nog wat wetenswaardigheden over kolen en olie productie neer.
Welnu, er zijn nu nog wat aanvullende verhalen van van elkaar onafhankelijke bronnen verschenen.
Een citaat uit het eerste stukje:
Therefore any new analysis of global coal supplies, following on the heels of the EWG report, warrants considerable interest.
We have not had to wait long. "The Future of Coal," a study by B. Kavalov and S. D. Peteves of the Institute for Energy (IFE), prepared for European Commission Joint Research Centre, is ready in final draft and will be published within days.
Unlike the EWG panel, Kavalov and Peteves did not attempt to forecast a peak in global production. Future supply is discussed in terms of the familiar but often misleading reserves-to-production (R/P) ratio. Nevertheless, the IFG’s conclusions are broadly supportive of the EWG report.
The three primary take-away conclusions from the new coal study are as follows:
Early in their paper the authors ask, "Will coal be a fuel of the future?" Their disturbing conclusion, many pages later, is that "The analysis in the preceding chapters indicates that coal might not be so abundant, widely available and reliable as an energy source in the future. "Along the way, they state "the world could run out of economically recoverable (at current economic and operating conditions) reserves of coal much earlier than widely anticipated."
En ook dat geeft te denken.
