$this->bbcode_second_pass_quote('mkwin', 'C')oal peaking in 15 years?? Do you have a link to this information? I can't remember exactly but the last figure I saw was an estimated 300 years potential supply.
(Sigh) Contrary to earlier comments, it is not hostility I am projecting, but perhaps frustration. Not only do I have a link, I created an entire forum just so people ( "who are not good at research") would have the info right at their fingertips in this site.
Coal: Resources and Future ProductionAs to the 300 years...again, sitting right there at the top of the Energy Forum. Easy to find, if one looks.
$this->bbcode_second_pass_quote('Montequest', 'T')otal proven world reserves of coal are estimated to total almost one trillion tons and are projected to last over 200 years at current rates of consumption. The US has about 250 billion tons of recoverable coal reserves. According to the EIA figures, we can see that we have 255 years of coal remaining in the year 2000 given our current rate of consumption. That prediction assumes equal use of all grades of coal, from anthracite to lignite. Population growth alone reduces the calculated lifetime to some 90-120 years. However, if we look back in history, we see that there were 300 years of coal reserves in 1988, 1000 years reserves in 1904, and 10,000 years reserves in 1868! As each year goes by, our coal consumption increases and we see that the projection becomes meaningless. And if we suddenly move to a bigger reliance on coal, and coal liquidfaction for gas, then this estimate would surely drop dramatically.
Coal peak projections:
Hubbert Model Peak 2032
EIA, Annual Energy Outlook 2004 Peak 2060
Flat gas consumption and greater coal consumption Peak 2053
Flat gas consumption and synfuels from coal to replace oil Peak 2035
