Jonathan Overly

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:

  • Fuels Fix alt-fuel news website and email – This Clean Cities stories and alternative fuel news website provides monthly updates to subscribers on alternative fuels news across the U.S.
  • 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.
  • Tennessee Green Fleets Certification Program – Tennessee’s only fleet certification program that reviews any size fleet to access it based on reduced petroleum use and emissions.
  • 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 currently serves on the Steering Committee for the EPA Region 4 Southeast Diesel Collaborative as well as on the Board of Directors for Transportation Energy Partners, and formerly served on the National Clean Cities Coordinators Council.” 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. In 2015, Overly was inducted into the Clean Cities Hall of Fame, joining a slew of other great coordinators that work hard to show dedication and leadership to the Clean Cities mission and serving fleets in their communities.
