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:
“It is now many years that men have resorted to the forest for fuel and the materials of the arts: the New Englander and the New Hollander, the Parisian and the Celt, the farmer and Robin Hood, Goody Blake and Harry Gill; in most parts of the world, the prince and the peasant, the scholar and the savage, equally require still a few sticks from the forest to warm them and cook their food. Neither could I do without them.”
—Henry David Thoreau (1817–1862)
““Never hug and kiss your children! Mother love may make your children’s infancy unhappy and prevent them from pursuing a career or getting married!” That’s total hogwash, of course. But it shows on extreme example of what state-of-the-art “scientific” parenting was supposed to be in early twentieth-century America. After all, that was the heyday of efficiency experts, time-and-motion studies, and the like.”
—Lawrence Kutner (20th century)
