The Dimensions of Energy
Corn:
„ Global corn crop – 680 MMT/year (2007)
„ Corn ethanol – 420 gallons per year
(typical for one acre of land – US Midwest)
Crude Oil:
„ Global petroleum – 5,000 MMT/year (2007)
(1,000 barrels per second or 1/3 x Colorado River)
„ Oil well – 1,500,000 gallons per year
(typical for 1.5” pipe – “average” oilfield)

„
„
Feedstock Sustainability
Critical Issues:
Potential non-food sources:
„
Wood, pulp, paper waste
„
Agricultural waste
„
New oilseed crops
„
Fast-growing grasses & trees
„
Microalgae
