What is ethanol?
Where is E85 available in TN? Thorntons, Twice Daily, Speedway, Pilot & other stations. See the TN E85 station map at the bottom of this page!
Different blends used by Tennessee fleets E10 and E85. E85 is 50-70% ethanol blended with gasoline, and is now called simply “flex fuel.”
Best resource for learning about ethanol www.ethanolrfa.org.The Renewable Fuels Association has numerous resources for consumers on their site, including “How is ethanol made?,” “Why is ethanol important? and “Ethanol blends and how they effect my engine.”
Ethanol is a cleaner-burning alternative fuel produced from domestic renewable resources such as corn and other starch-containing plant materials known as biomass. It can also be made from cellulosic materials such as switchgrass and crop residues.
How is it produced?
In the United States, ethanol is primarily produced from the starch in corn grain. Recent studies using updated data about corn production methods demonstrate a positive energy balance for corn ethanol, meaning that fuel production does not require more energy than the amount of energy contained in the fuel.
There are several steps involved in making ethanol available as a vehicle fuel:
- Biomass feedstocks are grown, collected and transported to an ethanol production facility
- Ethanol is produced from feedstocks at a production facility and then transported to a blender/fuel supplier
- Ethanol is mixed with gasoline by the blender/fuel supplier to make E10, E15 or E85, and distributed to fueling stations.
How is it used?
More than 95% of U.S. gasoline contains ethanol, typically E10 (10% ethanol, 90% gasoline), to oxygenate the fuel and reduce air pollution. Ethanol is also available as E85 (a gasoline-ethanol blend containing 51% to 83% ethanol, depending on geography and season). This fuel can be used in flexible fuel vehicles, which can run on high-level ethanol blends, gasoline, or any blend of these.
What are the benefits of ethanol?
The U.S. Department of Energy estimates for every one billion gallons of ethanol produced, 10,000 to 20,000 jobs are added to our domestic economy. – See more at: http://www.growthenergy.org/ethanol-issues-policy/economy/#sthash.spIUHru1.dpuf
In 2014 alone, the ethanol industry created and supported nearly 400,000 new jobs across the country that cannot be exported or outsourced. In addition, ethanol production contributed nearly $53 billion to the nation’s GDP and generated $5.7 billion in federal tax revenues. Ethanol production also plays a critical role in revitalizing America’s rural areas — some of the hardest hit by the economic downturn — by stimulating economic growth. – See more at: http://www.growthenergy.org/ethanol-issues-policy/economy/#sthash.spIUHru1.dpuf
According to the Department of Energy’s Argonne National Laboratory, ethanol reduces greenhouse gas emissions by an average of 34 percent in comparison to gasoline. Moreover, advanced biofuels have the potential to reduce greenhouse gas emissions by over 100 percent. Ethanol from any source has a positive net energy balance — meaning it gives more energy than is needed to produce it.
In 2014, the 13.4 billion gallons of ethanol blended into gasoline in the United States helped reduce greenhouse gas emissions from on-road vehicles by approximately 38 million metric tons, which is the equivalent of removing roughly 8 million automobiles from the road. Imagine if we were using more ethanol in our motor fuels.
Ethanol is already replacing millions of barrels of imported petroleum. That’s petroleum that could have ended up in our environment, devastating coastal industries, ecosystems and communities. Ethanol is clean burning, renewable, and it’s grown right here in America.
The EPA estimates that higher Renewable Fuel Standards will reduce Greenhouse Gas Emissions from transportation by a total of 6.8 billion tons CO2 equivalent when measured over a 100-year timeframe. This is the equivalent of approximately 160 million tons CO2 equivalent per year. The overall reductions would be like removing 24 million vehicles from the road.

What are the emissions reductions gained from ethanol?
The carbon dioxide released when ethanol is burned is balanced by the carbon dioxide captured when the crops are grown to make ethanol. This differs from petroleum, which is made from plants that grew millions of years ago. On a life cycle analysis basis, corn-based ethanol production and use reduces greenhouse gas emissions (GHGs) by up to 52% compared to gasoline production and use. Cellulosic ethanol use could reduce GHGs by as much as 86%.
