Kentucky’s Mammoth Cave National Park was the first national park in the country to be powered completely by alternative fuels.

Melissa Howell, Executive Director of the Kentucky Clean Fuels Coalition, recently reported this success to state lawmakers in Frankfort, Kentucky.

“Mammoth Cave has set a tremendous example for other parks across the country,” Howell said. “The park’s commitment to alternative fuels is far-reaching and includes biodiesel, E-85, electric and propane. Everything at Mammoth – even the ferries that operate on the Green River – are all fueled by alternative fuels or advanced technologies.”

Spanning over 52,000 acres, Mammoth Cave National Park preserves the world’s longest known cave system and a part of the Green River valley and hilly country of south central Kentucky.

Other biodiesel users in Kentucky include: the UPS Worldport hub in Louisville; Carmeuse Lime Mine; Jefferson and Warren County Public Schools; Lexington-Fayette Urban County Government; Louisville International Airport; Louisville Metro Government; Metropolitan Sewer District; the University of Kentucky; the University of Louisville and Murray State University
