The ethanol program is controversial for several reasons, not the least of which was that the ethanol industry was dominated by one company – Archer Daniels Midland of Peoria, Ill. In 1984, the number of ethanol plants peaked at 163 in the U.S., producing 595 million US gallons (2,250,000 m 3) of ethanol that year.
The world's first commercial wood-to-ethanol plant began operation in Japan in 2007, with a capacity of 1.4 million liters/year. The first wood-to-ethanol plant in the United States is planned for 2008 with an initial output of 75 million liters/year. [90] Other second-generation biofuels may be commercialized in the future and compete less ...
Since the 1970s, the U.S. has subsidized ethanol produced from food crops, especially from corn, thus providing a homegrown, alternative fuel source for our automobiles. But for multiple reasons ...
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, Canada, and Europe (see also Ethanol fuel by country). [2]
Food vs fuel is the debate regarding the risk of diverting farmland or crops for biofuels production in detriment of the food supply on a global scale. Essentially the debate refers to the possibility that by farmers increasing their production of these crops, often through government subsidy incentives, their time and land is shifted away from other types of non-biofuel crops driving up the ...
If Biden can deliver on the promise of his policies, it would not only redound to his political benefit but also put Americans on a greener path, writes Meg Jacobs.
The production of fuel ethanol from corn in the United States is controversial for a few reasons. Production of ethanol from corn is 5 to 6 times less efficient than producing it from sugarcane. The reason that corn has been notoriously used for ethanol production is because farmers are either paid to destroy crops or to not grow corn crops.
Sugarcane ethanol has an energy balance seven times greater than corn ethanol. [101] As of 2007, Brazilian distiller production costs were 22 cents per liter, compared with 30 cents per liter for corn-based ethanol. [102] Corn-derived ethanol costs 30% more because the corn starch must first be converted to sugar before distillation into ...
