that is bogus. even if you count the rain that falls from the sky to grow the corn, I believe you have it backwards.
The standard design was 3 gallons of water to produce one gallon of ethanol. But improvements in technology has gotten some producers down to 2.5 gallons. And other feed and energy co-products are produced along with the ethanol.
By comparison oil refineries are located on the coasts largely due to the amount of water required that cannot be obtained inland. That is why they don't build refineries in Canada, Wyoming, Montana, or N Dakota - where a very large portion of our oil comes from. There isn't enough water for them. But there are plenty of ethanol plants.
It takes 1,851 gallons of water to refine a barrel of crude oil. One barrel of crude oil produces 19 gallons of gasoline and 10 gallons of diesel fuel, in this respect it takes 97 gallons of water to produce a gallon of gasoline. If you combine gasoline and diesel, it takes 63 gallons of water to produce a gallon of "fuel." A total of 42 gallons of petroleum products are produced from a barrel of crude oil, in this respect it takes 44 gallons of water to produce each gallon of petroleum.
