The East Tennessee Clean Fuels Coalition (ETCleanFuels) is a local non-profit designated as a member of the Department of Energy Clean Cities program in 2006. ETCleanFuels works to diversify transportation fuels away from petroleum and reduce fuel usage through projects promoting alternatives like propane, ethanol, biodiesel, electricity, and natural gas. One focus is propane, a domestically produced fuel that is cheaper and less polluting than gasoline or diesel. ETCleanFuels facilitates projects and provides information on the benefits and incentives for using propane vehicles and infrastructure in the region.
