Great Smoky Mountains National Park

Great Smoky Mountains National Park has worked with the Land-of-Sky Clean Vehicles Coalition and the East Tennessee Clean Fuels Coalition to reduce petroleum use inside the park. Biodiesel (B20 to B50) powers more than 50 park vehicles and pieces of heavy equipment. More than a dozen hybrid electric vehicles and neighborhood electric vehicles in the park's fleet help improve air quality and raise awareness among visitors.

On December 25, 2010, MotorWeek aired a special on alternative fueled vehicles in the Great Smoky Mountains National Park.
