Question: is ethanol a good source of fuel for automobiles

Answer: Yes, Ethanol fuel is ethyl alcohol, the same type of alcohol found in alcoholic beverages, used as fuel. It is most often used as a motor fuel, mainly as a biofuel additive for gasoline. The first production car running entirely on ethanol was the Fiat 147, introduced in 1978 in Brazil by Fiat. Ethanol is commonly made from biomass such as corn or sugarcane. World ethanol production for transport fuel tripled between 2000 and 2007 from 17×10 liters (4.5×10 U.S. gal; 3.7×10 imp gal) to more than 52×10 liters (1.4×10 U.S. gal; 1.1×10 imp gal). From 2007 to 2008, the share of ethanol in global gasoline type fuel use increased from 3.7% to 5.4%. In 2011 worldwide ethanol fuel production reached 8.46×10 liters (2.23×10 U.S. gal; 1.86×10 imp gal) with the United States of America and Brazil being the top producers, accounting for 62.2% and 25% of global production, respectively. US ethanol production reached 57.54×10 liters (1.520×10 U.S. gal; 1.266×10 imp gal) in 2017-04.
