East Tennessee Clean Fuels history

east tennessee clean fuelsEast Tennessee Clean Fuels’ (ETCleanFuels) mission is to increase the use of cleaner American fuels and vehicles and energy-saving transportation technologies to improve air quality and health, curb dependence on imported petroleum and support Tennessee’s economy. More specifically, we work to implement alt fuel projects in East Tennessee, and work to make ETCleanFuels a sustainable coalition of involved participants from across East Tennessee.

ETCleanFuels is a designated coalition with the U.S. DOE Clean Cities Program, which resides within the Vehicle Technologies Program as part of the Office of Energy Efficiency & Renewable Energy (EERE) within DOE. Our designation ceremony was held on October 12, 2004 on the front lawn of the Headquarters for the Great Smoky Mountains National Park, just next door to Sugarlands Visitor Center.

The Coalition covers 47 counties in East and Middle Tennessee, and together with its partner, Middle-West Tennessee Clean Fuels, covers the entirety of Tennessee with the aim of increasing alternative fuels adoption and awareness. Together, our two Coalitions operate as “Tennessee Clean Fuels,” which serves the entire state and is made up of the staff and board members of the two state coalitions.

We have a “Board of Directors & Advisors” and the coordinator/executive director (ED) and staff of the Coalition is accountable to them. ETCleanFuels operates as a 501(c)3 nonprofit organization. We maintain tax exempt status in Tennessee and provide a Corporate Annual Report and Charitable Solicitations report to the Secretary of State every year. The Coalition has a contract with the University of Tennessee at Knoxville (UTK) for our full-time staff, and our offices are housed within UTK at the Institute for a Secure and Sustainable Environment (ISSE), which is located in the UT Conference Center Building in downtown Knoxville.
