Driving Energy Independence
It’s more affordable than traditional gasoline, reduces harmful vehicle emissions, supports nearly 300,000 American jobs and protects America’s energy independence. In 2019, ethanol displaced over 500 million barrels of crude oil and petroleum import dependence fell to just 4 percent compared to 60 percent in 2005. Without ethanol, petroleum import dependence would have been 10 percent.
Producing Food AND Fuel
Ethanol biorefineries make more than fuel; they also generate highly nutritious animal feed like distillers grains. One-third of every bushel processed by a plant is used to make animal feed, resulting in the production of more than 39 million metric tons of feed in 2019 alone. The low cost and nutritional properties of distillers grains make it one of the most sought-after feed ingredients in the world.
A Cleaner, Greener Fuel
Ethanol is responsible for removing the carbon equivalent of 11.5 million cars from the road. At the same time, the environmental impacts of producing ethanol have been greatly reduced. Natural gas and electricity use at dry mill ethanol plants has fallen nearly 40 percent since 1995, while consumptive water use has been cut in half. This has occurred while the amount of ethanol produced from a bushel has increased. Producers are getting 15 percent more ethanol from a bushel of corn than 20 years ago. The result? A smaller carbon footprint and an increase in energy efficiency. Ethanol use reduces greenhouse gas emissions by 40-45 percent compared to gasoline–even when hypothetical land use change emissions are included. By displacing hydrocarbon substances like aromatics in gasoline, ethanol also helps reduce emissions of air toxics, particulate matter, carbon monoxide, nitrous oxides, and exhaust hydrocarbons.
Today’s producers get more ethanol out of every bushel. On average, 1 bushel of corn (56 pounds) processed by a dry mill ethanol plant produces: 2.86 gallons of denatured fuel ethanol; 15.9 pounds of distillers grains animal feed; 0.75 pounds of corn distillers oil; and 16.5 pounds of biogenic carbon dioxide.
Providing More Consumer Options
We know Americans are looking for more competition and greater savings for the fuel that powers their vehicles. Nearly all U.S. gasoline today contains 10 percent ethanol, and the use of 15 percent ethanol blends and flex fuels like E85 is increasing. 15 percent ethanol blends (E15) are higher quality fuels that offer greater savings. The EPA has approved E15 use in more than 90 percent of the existing U.S. auto fleet, and 9 out of 10 new cars carry the manufacturer’s warranty and approval for E15.
Expanding Global Markets
The United States is the world’s leading ethanol producer. Even in the face of new trade barriers in key markets, U.S. ethanol exports were 1.5 billion gallons in 2019. U.S. ethanol was shipped to Canada, Brazil, India, South Korea and the Philippines and many other countries in 2019.
Today’s ethanol biorefinery operates much like a chemical refinery, able to produce multiple renewable fuels and products. Some biorefineries are producing biodiesel and renewable diesel from corn distillers oil, but the largest impact has been in corn kernel fiber production. The addition of “bolt-on” technologies has allowed ethanol producers to expand yields by processing ethanol from corn fiber, a cellulosic portion of the grain. Unleashing corn kernel fiber ethanol production could result in existing ethanol plants producing hundreds of millions of gallons of cellulosic ethanol.
