Ethanol is a renewable fuel made from corn and other plant materials. The use of ethanol is widespread—almost all gasoline in the U.S. contains ethanol in a low-level blend. Ethanol is also available as E85—a high-level ethanol blend—for use in flexible fuel vehicles. Kentucky Corn Growers offer funding to every new retail site and almost every gallon of gasoline in Kentucky contains 10% ethanol (E10).  Kentucky produces 40 million gallons of ethanol, and 12 million bushels of corn are used to produce fuel ethanol in Kentucky. The commonwealth is also investigating the use of biomass and algae for fuel ethanol production.

Ethanol Projects in Kentucky

NASCAR using E15 at Kentucky Speedway

Sparta, Kentucky

Since 2011 vehicles racing at Kentucky Speedway for the NASCAR Cup series events are fueled with Sunoco Green 15, a gasoline blended with 15% American, corn-based ethanol. Drivers and pit crews are reporting better engine performance in addition to the reduced CO2 emissions. The NASCAR - American Ethanol partnership is supported by Kentucky Corn Growers Association to share the benefits of American ethanol with NASCAR’s 75 million fans.

Mammoth Cave National Park

Mammoth Cave, KY

Mammoth Cave National Park became the first unit in the Department of the Interior to develop an on-site fueling station using E-85, and is the first national park in the country to be powered by 100% alternative fuel. More than 90 percent of the vehicles used by Mammoth Cave run on either E10 or E85. Mammoth Cave National Park sits on more than 52,000 acres and has 80+ employees.

I-75 Green Corridor Project

Since 2009, 30+ partners have been collaborating on the “longest biofuels corridor on the planet” by making all 1,786 miles of the U.S. interstate I-75 traversable using either of the biofuels E85 ethanol or B20 biodiesel.  Through 2013, the project has added 28 E85 stations and 9 B20 stations in all 6 of the corridor states, and those stations have sold over 2.4 million gallons of biofuels!  By the project’s end, we expect to be offsetting nearly 1.5 million GGEs per year of petroleum.
