Ethanol gas renewable?
A federal law requires refiners to double the use of ethanol in gasoline by
2012 but scientists say it burns more energy than it makes.
2.8 billion gallons of ethanol blended with gasoline in the U.S. every year
7.5 predicted by 2012
35 kilowatt-hours of energy needed to produce one gallon of gasoline
45 kilowatt-hours of energy needed to grow, harvest, and convert 22 pounds of corn into one gallon of ethanol
1.6 gallons of ethanol generate the energy equivalent of one gallon of gasoline 30% more energy ethanol burns than it creates
$1.25 cost of producing one gallon of gasoline
$4.69 cost of producing one gallon of ethanol
.5 (1/2) gallon of corn-based diesel - now in the works at the University of Wisconsin - can produce as much energy as one gallon of ethanol
