They claim that some ethanol engines have already produced 22% more miles per gallon than identical gasoline engines. [2] Ethanol advocates [who?] also state that it is a mistake to base ethanol engine design on gasoline engine design, and that ethanol engines should be based on diesel engine design parameters instead.
As of 2011, blenders received a US$0.45 per gallon tax credit, regardless of feedstock; small producers received an additional US$0.10 on the first 15 million US gallons; and producers of cellulosic ethanol received credits up to US$1.01. Tax credits to promote the production and consumption of biofuels date to the 1970s.
Ethanol fuel has a "gasoline gallon equivalency" (GGE) value of 1.5, i.e. to replace the energy of 1 volume of gasoline, 1.5 times the volume of ethanol is needed. [4] [5] Ethanol-blended fuel is widely used in Brazil, the United States, and Europe (see also Ethanol fuel by country). [2]
How much ethanol is in gasoline? In 2012, Americans consumed 134 billion gallons of gasoline that contained approximately 13 billion gallons of ethanol (a blend rate of 9.7%), according to the ...
The United States produced more than 13 billion gallons of corn ethanol in 2012 and is expected to produce a similar total in 2013. ... Corn ethanol production is capped at 15 billion gallons per ...
As of 2005, E85 is frequently sold for up to 36% lower price per quantity than gasoline. [10] Much of this discount can be attributed to various government subsidies, and, at least in the United States, the elimination of state taxes that typically apply to gasoline and can amount to 47 cents, or more, per gallon of fuel.
The energy content of ethanol is 76,100 BTU/US gal (5.89 kilowatt-hours per litre), compared to 114,100 BTU/US gal (8.83 kWh/L) for gasoline. (see chart above) A flex-fuel vehicle will experience about 76% of the fuel mileage MPG when using E85 (85% ethanol) products as compared to 100% gasoline. Simple calculations of the BTU values of the ...
According to the Renewable Fuels Association, the E15 waivers now cover 62% of vehicles on the road in the US, and the ethanol group estimates if all 2001 and newer cars and pickups were to use E15, the theoretical blend wall for ethanol use would be approximately 17.5 billion gallons (66.2 billion liters) per year.
