Ethanol fuel production by state. The United States became the world's largest producer of ethanol fuel in 2005. The U.S. produced 15.8 billion U.S. liquid gallons of ethanol fuel in 2019, and 13.9 billion U.S. liquid gallons (52.6 billion liters) in 2011, [1][2] an increase from 13.2 billion U.S. liquid gallons (49.2 billion liters) in 2010 ...
Ethanol fuel mixtures have "E" numbers which describe the percentage of ethanol fuel in the mixture by volume, for example, E85 is 85% anhydrous ethanol and 15% gasoline. Low-ethanol blends are typically from E5 to E25, although internationally the most common use of the term refers to the E10 blend. Blends of E10 or less are used in more than ...
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]
Until 2005 Brazil was the world's top producer of ethanol fuel when it was surpassed by the United States. Together both countries were responsible in 2011 for 87.1% of the world's ethanol fuel production. [1] In 2009 Brazil produced 27.5 billion liters (7.26 billion U.S. liquid gallons), [13] representing 35.9% of the world's total ethanol ...
However, in 2010, and as a result of supply concerns and high ethanol fuel prices, the government mandated a temporary 90-day blend reduction from E25 to E20 beginning February 1, 2010. [31] [39] By mid March 2015 the government raised temporarily the ethanol blend in regular gasoline from 25% to 27%.
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 ...
About 400 filling stations exist in the US that sell E85 fuel, mostly in the Midwest. Gasoline prices rise as ethanol prices stay the same, due to rapidly growing ethanol supply and federal tax subsidies for ethanol. Wholesale ethanol prices drop nearly 30% between January and April, or $1.75 to $1.23 per gallon in the U.S.
The first four aliphatic alcohols (methanol, ethanol, propanol, and butanol) are of interest as fuels because they can be synthesized chemically or biologically, and they have characteristics which allow them to be used in internal combustion engines. The general chemical formula for alcohol fuel is CnH2n+1OH.
