Jonathan Overly founded the East Tennessee Clean Fuels Coalition (ETCleanFuels) in 2002 and has managed it since its inception. He has spoken to thousands of people across east Tennessee including hundreds of companies and organizations about partnering to expand alternative fuel use in the area. Many government and industry fleets are coalition members. Although biodiesel was an early lead fuel for the coalition, in 2008 the coalition began expanded activities to focus on all of the alternatives, and currently has projects underway that are focused on expanding the use of CNG, propane, biodiesel, E85, TSE (truck stop electrification), LNG and full-size light-duty electric vehicles.

Some of ETCleanFuels major initiatives include:

  • Drive Electric TN – A partnership that promotes EVs and EVSE in Tennessee, as well as the Tennessee Workplace Charging Partnership and DOE's Workplace Charging Challenge.
  • Team TSE – A grant-based effort that is focused nationally on expanding awareness about TSE, and building support for this technology through the Team TSE Pledge (learn more about it on the website).
  • School Presentations – The ETCleanFuels team spent nearly a decade educating K-12 school students about the various alternative fuels and the dangers of continued oil-only reliance. Through 2012, they had reached over 20,000 students with such educational visits.
  • Tennessee NGV Task Force – A point source for providing information on the partnership that exists in Tennessee for expanding the use of natural gas vehicles, or NGVs.
  • CleanFuelsCorridor.com – ETCleanFuels managed partners across 6 U.S. states as they implemented the I-75 Green Corridor Project that turned the 1,726-mile long interstate into the planet's longest biofuels corridor. E85 and B20 are accessible along the entire corridor.

Overly formerly served on the National Clean Cities Coordinators Council; as well as on the Board of Directors for Transportation Energy Partners, the Univ. of Tennessee, Knoxville (UTK) Committee on the Campus Environment, and the Southeast Alternative Fuels Task Force. He currently serves as a Captain for annual National Drive Electric Week events in eastern Tennessee, and on the Steering Committee for the EPA Region 4 Southeast Diesel Collaborative. Overly has a Master of Science in Environmental Engineering from UTK. At the 2006 Alternative Fuels & Vehicles National Conference he was named the Clean Cities Coordinator of the Year, and has won several regional and state awards for advancing alternative fuels and improving air quality.
