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.
Using corn as a feedstock to produce either ethanol or butanol seems infeasible without significant technology improvements regarding yields. Currently, about 2.5 US gallons (9.5 L) of butanol can be produced per bushel of corn (373 l/t). [44] Meanwhile, about 2.75 US gallons (10.4 L) of ethanol can be produced per bushel of corn (410 l/t). [45]
"America's ethanol program is a product of government subsidies. There are more than 200 different kinds, as well as a 54 cents-a-gallon tariff on imported ethanol. This prices Brazilian ethanol out of an otherwise competitive market. Brazil makes ethanol from sugarcane rather than corn (maize), which has a better EROEI. Federal subsidies alone ...

For each billion ethanol-equivalent gallons of fuel produced and combusted in the US, the combined climate-change and health costs are $469 million for gasoline, $472–952 million for corn ethanol depending on biorefinery heat source (natural gas, corn stover, or coal) and technology, but only $123–208 million for cellulosic ethanol ...
An operating lignocellulosic ethanol production plant is located in Canada, run by Iogen Corporation. [32] The demonstration-scale plant produces around 700,000 litres of bioethanol each year. A commercial plant is under construction. Many further lignocellulosic ethanol plants have been proposed in North America and around the world.
The White House is stalling action on requests by Farm Belt states to allow regional sales of gasoline blended with higher volumes of ethanol after oil industry warnings that the move could cause ...
