Reserves/Production for Coal (years left) • In the U.S. • 1939, best estimate: 3800 years • 1953, best estimate: 1900 years • 1993, best estimate: 300 years • 2005, best estimate: 244 years World reserves (BP estimates): 1993 - 250 years 2005 – 155 years 3% growth – 65 years
Non-conventional Fuels • Tar sands – Alberta. • Large resource, low production rate (5 MMb/d in 25 yrs) • Low net energy • High cost ($25 - $50 /bbl) • Shale oil – Wyoming • Large resource, low production rate (1 MMb/d in 20 yrs) • Low net energy • High cost ($75 /bbl) • Corn ethanol • Low net energy • Food vs. fuel • Little greenhouse gas emission gain Rand Corp. report for US DOE, Nat’l.
