alternative fuel
Non-petroleum power source
Alternative fuel is any energy source for vehicles or machinery that substitutes for conventional petroleum-based fuels like gasoline and diesel.
The term encompasses electricity, natural gas, hydrogen, biodiesel, and ethanol, among others.
What counts as "alternative" shifts with context and time—natural gas is alternative relative to gasoline but conventional relative to hydrogen.
The city converted its bus fleet to alternative fuels.
