Mammoth Cave Gains National Distinction
Mammoth Cave in south central Kentucky is the first national park to become powered entirely by alternative fuels. Melissa Howell of the Kentucky Clean Fuels Coalition spoke to lawmakers in Frankfort this week.
"Everything down there, even the ferries that operate on the Green River, are powered by alternative fuels or advanced technologies," testified Howell. "That's one national park out of 380."
Howell said the U-S Department of Energy chose Mammoth Cave over Yellowstone National Park for the pilot project, which included purchasing four propane buses to bring visitors from the parking area to the cave entrances. Mammoth Cave also uses ethanol and bio-diesel fuels.
