Anybody got an estimate on the amount of water it takes to produce 12 billion gallons of ethanol?
Most put the figure at 3-4 gallons of water per gallon of ethanol produced. Some of the water doesn’t get consumed, just dirtied up. Some is lost by watering the corn crop.
Ethanol break even when gasoline is about $5 a gallon. Some financial papers said this. Notice how many ethanol producers are now going broke.
Ethanol produces twice the CO2 as regular gasoline. So said CARB, before the gubernator forced them to take the data down.
ethanol is wasteful, and too expensive, which is why it was dropped from the fuel list for cars a hundred years ago.
