The fuel efficiency of ethanol is 3% to 4%, for biogas is 20.44% to 22.22%, for biodiesel is 1% to 2% less than petroleum, and for wood is 72% for catalytic wood stoves and 63% for non-catalytic wood stoves.
In its simplest form , fuel efficiency is characterized by the amount of energy in the fuel that a vehicle will transform into kinetic energy to make the journey.
At its most basic, fuel-efficiency refers to a vehicle's ability to extract energy from fuel.
The more power a vehicle can retrieve from fuel, the greater the vehicle's fuel efficiency.
Ethanol has a fuel efficiency of 3% to 4%, biogas has a fuel efficiency of 20.44% to 22.22%, biodiesel has a fuel efficiency of 1% to 2% just under petroleum, and wood has a fuel efficiency of 72% for catalytic wood burning stoves as well as 63% for non-catalytic wood stoves.
Thus, above mentioned is the fuel efficiencies for different materials.
