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]
Those estimates hint that $4 per bushel corn might be priced at only $3 without demand for ethanol fuel." [180] Reviewing eight years of actual implementation of the Renewable Fuel Standard, researchers from the University of Wisconsin found the standard increased corn prices by 30% and prices of other crops by 20%.

For comparison, that same one unit of fossil fuel invested in oil and gas extraction (in the lower 48 States) will yield 15 units of gasoline, a yield an order of magnitude better than current ethanol production technologies, ignoring the energy quality arguments above and the fact that the gain (14 units) is both declining and not carbon neutral.
Corn ethanol has yet to be proven to be as cost effective as gasoline due to corn ethanol being much more expensive to create compared to gasoline. [6] Corn ethanol has to go through an extensive milling process before it can be used as a fuel source. One major drawback with corn ethanol, is the energy returned on energy invested , meaning the ...
Ethanol's chemical composition. Similar to other gasoline structures, biodiesel is built from a foundation of hydrocarbons. BG100, or 100% biogasoline, is formulated so that it can immediately be used as a drop-in substitute for petroleum-derived gasoline in any conventional gasoline engine, unlike ethanol.
In September 2014, The American Petroleum Institute on Thursday accused the White House accused of attempting to use 2014 biofuel targets to influence a tight U.S. Senate race, stating that increase in the targets could raise the price of gasoline. The Renewable Fuel Standard requires increasing amounts of ethanol and biodiesel to be mixed into ...
Renewable fuels are fuels produced from renewable resources. Examples include: biofuels (e.g. Vegetable oil used as fuel, ethanol, methanol from clean energy and carbon dioxide [1] or biomass, and biodiesel), Hydrogen fuel (when produced with renewable processes), and fully synthetic fuel (also known as electrofuel) produced from ambient carbon dioxide and water.
Carbon-neutral fuel is fuel which produces no net-greenhouse gas emissions or carbon footprint. In practice, this usually means fuels that are made using carbon dioxide (CO 2 ) as a feedstock . Proposed carbon-neutral fuels can broadly be grouped into synthetic fuels , which are made by chemically hydrogenating carbon dioxide, and biofuels ...
