You would need 26 million Priuses to achieve Ethanols current GHG emissions reduction[/font]
Ethanol currently represents approximately 10% of our light vehicle fuel supply. With GHG reductions of 34% (
Argonne National Laboratory - 2012) Ethanol, at ~10% of the fuel supply, in total produces a 3.38% reduction in the GHG emissions of the entire Light Vehicle fleet.
..... So how many Toyota Priuses would it take to achieve that much of a GHG emissions reduction? We must convert the 3.38% GHG emissions to an equivalent number of cars and light trucks. To do this we apply Ethanols aggregate GHG emissions reduction (i.e. as a percentage of the GHG emissions for the entire fleet) to the total number of vehicles comprising the entire fleet of automobiles and light trucks, or 250 million vehicles. Thus, 3.38% of 250 million vehicles would be approximately 8.4 million vehicles.
.... Since the Prius reduces gasoline consumption about 32.6% compared to a Toyota Corolla (a vehicle of comparable weight and payload), dividing 8.4 million vehicles by .326 gives you slightly more than 25.7 million Priuses which would be required to produce the same amount of GHG emissions reduction as Ethanol currently does, for the entire light vehicle fleet.
