From International Energy Agency 2008 Report.
"World energy demand expands by 45% between now and 2030 –an average rate of increase of 1.6% per year –with coal accounting for more than a third of the overall rise"

"Demand for coal has been growing faster than any other energy source & is projected to account for more than a third of incremental global energy demand to 2030"

For good or for bad coal looks like it has a bright future.
