Ethanol derived from corn would require 50 gallons of water per mile, when all the water needed in irrigation of crops and processing into ethanol is considered.
Fuel derived from irrigated sorghum uses as much as 115 gallons per mile.
Moreover, increasing production of biofuels from row crops will likely result in more water pollution due to soil erosion and the increased use of pesticides to grow enough crops…
