E85 is a blend of ethanol and gasoline, typically 85% ethanol and 15% gasoline. It is an eco-friendly alternative to gasoline as it produces fewer emissions. The carbon dioxide released when ethanol is burned is offset by the carbon dioxide captured when the crops used to make the ethanol are grown. This is not the case with gasoline, which is refined from petroleum extracted from the earth. E85 has a smaller carbon footprint than gasoline, with studies showing that it reduces greenhouse gas emissions by up to 50% more than gasoline. However, there are some drawbacks to using E85, including a slight decrease in fuel economy and the need to evaporate water from the oil regularly. Despite this, E85 is a popular choice for flex-fuel vehicles, with growing infrastructure for its retail sale, particularly in corn-growing states in the US Midwest.

What You'll Learn
E85 is an eco-friendly alternative to gasoline
E85 has a significantly lower carbon footprint than gasoline. A vehicle's carbon footprint can be reduced by 35% if E85 is used as the primary fuel source. This is because the carbon dioxide released when ethanol is burned is offset by the carbon dioxide captured when the feedstock crops are grown to produce ethanol. On the other hand, gasoline and diesel are refined from petroleum extracted from the earth, and no emissions are offset when these petroleum products are burned.
Several studies have confirmed that corn ethanol production results in much lower greenhouse gas emissions than the same amount of gasoline production. For example, a study by the Argonne National Laboratory found that using corn-based ethanol instead of gasoline reduces lifecycle greenhouse gas emissions by an average of 40%. Another study by the same laboratory found that using cellulosic ethanol provides an even greater benefit, with emissions reductions ranging from 88% to 108% compared to conventional gasoline.
In addition to its environmental benefits, E85 also offers improved engine performance. Engines running on E85 have lower operating temperatures, higher knock resistance, and increased torque. However, one disadvantage of E85 is that it may result in slightly lower fuel economy, with vehicles burning more fuel to travel the same distance as with gasoline. Despite this, the use of E85 is becoming increasingly popular, with record sales reported in California and Minnesota in recent years.

E85 reduces greenhouse gas emissions
E85 is an eco-friendly alternative to regular gasoline. It is a blend of 85% ethanol and 15% gasoline or other hydrocarbons by volume. While some critics have written off E85 as a "dead fuel", it has gained popularity in recent years, with record sales reported in California and Minnesota. E85 is produced by distilling corn into ethyl alcohol (ethanol). The ethanol industry is the second-largest customer of the US corn industry, with about 30% of the field corn grown in the US being used for ethanol production.
The American Coalition for Ethanol also found that flex fuel reduces greenhouse gas emissions by at least 50% more than gasoline. This is because gasoline contains many different hydrocarbons and additives, some of which are harmful to the environment. When a vehicle burns gasoline, these harmful substances are pumped into the air. In contrast, the ethanol in E85 does not contain harmful hydrocarbons or additives, allowing it to run much cleaner.
While E85 may result in slightly lower miles per gallon (MPG) than gasoline, this does not offset the environmental benefits. Even in cases where E85 reduces a vehicle's MPG, it still produces fewer emissions than gasoline. The environmental impact of E85 is also likely to shrink over time as infrastructure and technology improve.

E85 is cheaper than gasoline
E85 is a blend of 85% ethanol and 15% gasoline. It is an eco-friendly alternative to gasoline, with a carbon footprint that is 35% smaller. This is because the carbon dioxide released when ethanol is burned is offset by the carbon dioxide captured when the crops used to make the ethanol are grown. In addition, ethanol does not contain harmful hydrocarbons or additives, which are present in gasoline and are pumped into the air when it is burned.
E85 is also cheaper than gasoline. In 2011, E85 was around 20% less expensive than gasoline. While E85 can lead to a drop in fuel economy, meaning that vehicles burn more fuel to go the same distance, this is more than offset by the lower price of E85. In fact, E85 can be up to 60% cheaper than premium gasoline.
The use of E85 has been encouraged by government subsidies in the United States, particularly in corn-growing states in the Midwest. The American Jobs Creation Act of 2004 created the Volumetric Ethanol Excise Tax Credit (VEETC) to subsidize production costs, and other measures have been implemented to jump-start ethanol production. Despite this, take-up has been low, and E85 is now only available at a small number of outlets.
E85 is particularly popular with drivers of flex-fuel vehicles (FFVs), with record sales reported in California and Minnesota. In countries like Australia, E85 is used extensively by performance motoring enthusiasts and motor racing clubs and championships.

E85 has a lower carbon footprint
The carbon dioxide released when ethanol is burned as vehicle fuel is offset by the carbon dioxide captured when the crops used to make the ethanol are grown. This is not the case with gasoline and diesel, which are refined from petroleum extracted from the earth. No emissions are offset when these petroleum products are burned. On a life cycle analysis basis, greenhouse gas (GHG) emissions are reduced on average by 34% with corn-based ethanol produced from dry mills, and range between 88% and 108% if cellulosic feedstocks are used, compared with gasoline and diesel production and use.
A study by the Argonne National Laboratory found that using corn-based ethanol in place of gasoline reduces life cycle GHG emissions on average by 40%. Using cellulosic ethanol provides an even greater benefit. A 2012 study by the same laboratory found that when fuel life cycles are considered, average emissions reductions of cellulosic ethanol compared to conventional gasoline range from 88% to 108% depending on feedstocks used.
In addition, E85 does not contain harmful hydrocarbons or additives, unlike gasoline. This means that E85 runs much cleaner than gasoline. One source states that flex fuel reduces greenhouse gas emissions by at least 50% more than gasoline. Another source states that a vehicle's carbon footprint goes down by 35% if E85 is used as the primary fuel source.

E85 is subsidised by the US government
E85 is an abbreviation for an ethanol fuel blend of between 51% and 83% denatured ethanol fuel and the remainder being gasoline or other hydrocarbons. It is an eco-friendly alternative to regular gasoline, with a carbon footprint that is much smaller than that of gasoline. In fact, a vehicle's carbon footprint can go down by 35% if E85 is used as the primary fuel source.
The US government has provided various subsidies for E85, which has kept the price of E85 significantly lower than that of gasoline. For example, as of 2005, E85 was sold for up to 36% lower than the price of gasoline per quantity. This discount can be largely attributed to the US federal tax exemption on ethanol, which was initially due to expire in 2007 but may have been extended. This exemption is what keeps ethanol economically competitive with petroleum fuel products. Additionally, E85 is exempt from certain state taxes that apply to gasoline, which can amount to 47 cents or more per gallon of fuel.
The US government has also implemented policies to promote the use of E85. For instance, the Energy Policy Act of 2005 mandated that federal fleet flexible-fuel vehicles (FFVs) operate on alternative fuels such as E85 100% of the time, effectively doubling the government's use of E85. Furthermore, the US Environmental Protection Agency (EPA) approved the use of E15, a higher octane fuel with 85% ethanol, for model year 2001 and newer cars, light-duty trucks, medium-duty passenger vehicles, and all FFVs in 2012. This approval has encouraged many automobile companies, including Ford, Chrysler, and GM, to sell flexible-fuel vehicles that can run on blends ranging from pure gasoline to E85.
The subsidization of E85 by the US government has made it a more affordable option for consumers and has helped to reduce greenhouse gas emissions. By encouraging the use of E85, the government is taking steps towards slowing down climate change and reducing the country's dependence on outside energy sources.
