Fuel Efficiency In Transportation
The energy efficiency of different types of transportation range from some hundred kilojoule per kilometre for a bicycle to several megajoule for a helicopter.
Efficiency can be expressed in terms of:
- distance per vehicle per consumption volume (mile per gallon : mpg us or imp)
- distance per vehicle per consumption weight (km per kg)
- consumption per unit distance per vehicle (European measure in liter per hundred kilometer : l/100 km),
- consumption per unit distance per passenger
- consumption per unit distance per unit mass of cargo transported.
Energy efficiency is important as it is one factor that affects the cost of transportation and the range of the vehicle. Some may also see it as a relevant concept to increase autonomy and reduce environmental impact.

Famous quotes containing the words fuel and/or efficiency:
“I had an old axe which nobody claimed, with which by spells in winter days, on the sunny side of the house, I played about the stumps which I had got out of my bean-field. As my driver prophesied when I was plowing, they warmed me twice,—once while I was splitting them, and again when they were on the fire, so that no fuel could give out more heat. As for the axe,... if it was dull, it was at least hung true.”
—Henry David Thoreau (1817–1862)
“I’ll take fifty percent efficiency to get one hundred percent loyalty.”
—Samuel Goldwyn (1882–1974)
