Vinod Khosla in "My Big Biofuels Bet" (RC,WW 520-527) has "been searching for a renewable fuel that could realistically replace the 140 billion gallons of gasoline consumed in the U.S. each year" (521). He further believes that "corn ethanol is a crucial fist step toward kicking our [USA] oil addiction" (521) by using "cow manure--because this waste powers a facility that turns corn into ethanol" (521). He answers the objection that "there's not enough land to grow crops for ethanol" (527) by saying that "taking land now used to grow export crops and instead planting energy crops, it's feasible to eliminate our need to import oil for gasoline" (527).
Do you believe "that Americans are addicted to oil and alternative fuels are our only salvation" (529)? What do you think about replacing food crops with fuel crops?
