About $6 billion is spent yearly by the U.S. government to subsidize corn ethanol. Around 1700 gallons of water are consumed for every gallon of corn ethanol produced. Corn is the number one cause of soil erosion in the United States and its overdependence on nitrogenous fertilizer, herbicides and insecticides is the prime reason of the dead zone in the Gulf of Mexico. Yet, corn ethanol produces only 1.3 percent of nation’s total oil consumption, which, according to Prof. David Pimentel, entomology, defeats the purpose of energy sustainability.
