Clean Fuels

Clean Cities Georgia is committed to advancing affordable, domestic transportation fuels, energy efficient mobility systems, and other fuel-saving technologies and practices throughout our region. As a “fuel agnostic” organization, we support all alternative fuel options equally. Overall, our goal is to reduce the usage of petroleum through the promotion of alternative, cleaner alternatives.

Biodiesel is a renewable, biodegradable fuel manufactured domestically from vegetable oils, animal fats, or recycled restaurant grease. It is often promoted as a cleaner alternative to petroleum diesel, since it both reduces oil dependency and increases the use of renewable fuels.


Ethanol is a biodegradable, renewable fuel made from corn and plant matter. Its use is widespread, as 98% of all gasoline consumed in the United States contains a blend of Ethanol. To reduce their environmental impact, many vehicle owners will use blends with  higher percentages of ethanol.


Electric vehicles (EVs), including both hybrid electric vehicles and full electric vehicles, are capable of drawing electricity either directly from the grid or from other off-board electric power sources. This energy is then stored in batteries and used to fuel the vehicle. Electricity is quickly becoming one of the most popular alternative fuel sources.

Natural Gas

Natural gas is an odorless, gaseous mixture of hydrocarbons, predominantly made up of methane (CH4). There are multiple different types of natural gas used as fuel, most notably compressed natural gas (CNG), liquified natural gas (LNG), and renewable natural gas (RNG). All of the different varieties reduce carbon emissions to some extent, though RNG has a much greater, positive environmental impact. 


Propane is a three-carbon alkane gas (C3H8). It is stored under pressure inside a tank as a colorless, odorless liquid. Sometimes known as liquefied petroleum gas (LPG), petroleum is a clean-burning alternative fuel that’s been used for decades to fuel light, medium and heavy-duty propane vehicles.
