Sobering thoughts on ethanol production from USA Today
Let’s do some math.
To get a gallon of ethanol, you need a little more than 26 pounds of corn, and an acre of land can yield about 9,400 pounds per year. In other words, one acre of land can generate about 362 gallons of ethanol per year.
But people in the U.S. use about 174 million gallons of gasoline per day just for their cars (so says the Department of Energy). If the Magic Fairy came down and all our cars suddenly ran on ethanol we would need about 261 million gallons per day.
That would require more than 260 million acres of corn to produce. Considering that in 2000 farmers in the U.S. harvested about 73 million acres of corn, it looks like they’ll need to get cracking.
