Ethanol uses a lot of water

A proposed ethanol plant in Illinois will require 200 million gallons of water per day to generate the 100 million gallon per year capacity. So some simple math, every day this plant will use double it's yearly ethanol production capacity in water. So the ratio of water to ethanol is 730:1. So it takes 730 gallons of water to produce one gallon of ethanol. Damn. Oh and this doesn't include the amount of water used in the growing of the raw material, usually corn.
Ethanol isn't looking so good these days with concerns over it's impact on biodiversity, questionable CO2 reductions, and it's huge consumption of water. According to this site, the facts about ethanol, the US has the capacity to make 4.5 billion gallons of ethanol a year, meaning it consumes 3.2 trillion gallons of water to do it. That's a lot of water.
