Mammoth Cave National Park

Mammoth Cave National Park started using E85 in 1999 and today runs all its vehicles on alternative fuels. Thanks to new funding, the park added four propane-powered school buses, two propane-powered pickup trucks, and one electric utility vehicle to its fleet. In addition, park personnel partnered with the Kentucky Clean Cities Partnership to enhance efforts to educate visitors, employees, and the media about the benefits of using alternative fuels.
