Peak Coal.

Peak coal: sooner than you think

"Looking to the future, many analysts who are concerned about emerging supply constraints for oil and gas foresee a compensating shift to lower-quality fuels. Coal can be converted to a gaseous or liquid fuel, and coal gasification and coal-to-liquids plants are being constructed at record rates.

This expanded use of coal is worrisome to advocates of policies to protect the global climate, some of whom place great hopes in new (mostly untested) technologies to capture and sequester carbon from coal gasification. With or without such technologies, there will almost certainly be more coal in our near future.

According to the widely accepted view, at current production levels proven coal reserves will last 155 years (this according to the World Coal Institute). The US Department of Energy (USDoE) projects annual global coal consumption to grow 2.5 per cent a year through 2030, by which time world consumption will be nearly double that of today."
