“Much of the ethanol produced in the world is actually a petroleum product. It is easily made by the hydrolysis of ethylene, a major petrochemical. Two million tons of petroleum-derived ethanol is produced annually.”
number sounds impressive until you compare:
2 million tons x 2000lb/ton = 4000000000 pounds
4000000000 / 7 lbs per gallon = 571 million gallons
amount of ethanol produced in the US from corn = 15 billion gallons
“Much of the ethanol produced in the world is actually a petroleum product.”
5%. And it does not go into gas tanks.
