Energy efficiency in transport can be measured in L/100 km or miles per gallon (mpg). This can be normalized per vehicle, as in fuel economy in automobiles, or per seat, as for example in fuel economy in aircraft.
Traditionally, litres per mil were used in Norway and Sweden, but both have aligned to the EU standard of L/100 km. [1] Fuel consumption is a more accurate measure of a vehicle's performance because it is a linear relationship while fuel economy leads to distortions in efficiency improvements. [2]
On the other hand, Intermodal container shipping rates depend heavily on the route taken over the weight of the cargo, just as long as the container weight does not exceed the maximum lading capacity. Prices can vary between $300-$10,000 per Twenty foot equivalent unit (TEU) depending on the supply and demand of a given route. [3]
The average price of regular unleaded gas in Florida as of Friday, Dec. 15, is $2.886, 16 cents cheaper than the same time the week before and well below the national average of $3.087.
By 2010 this had increased to 23.0 miles per US gallon (10.2 L/100 km; 27.6 mpg ‑imp). Average fuel economy in the United States gradually declined until 1973, when it reached a low of 13.4 miles per US gallon (17.6 L/100 km; 16.1 mpg ‑imp) and gradually has increased since, as a result of higher fuel cost.

Assuming the Emma Maersk consumes diesel (as opposed to fuel oil which would be the more precise fuel) then 1 kg diesel = 1.202 litres = 0.317 US gallons. This corresponds to 46,525 kJ. Assuming a standard 14 tonnes per container (per teu) this yields 74 kJ per tonne-km at a speed of 45 km/h (24 knots).
The gas price prior to reform was $0.10 US per liter with the quota of 100 liters per month per passenger car. The reform raised the price to $0.40 US per liter and later reduced the ration to 60 liters per month. The price for over-quota consumption and the imported cars were $0.70 US per liter.
The energy content of ethanol is 76,100 BTU/US gal (5.89 kilowatt-hours per litre), compared to 114,100 BTU/US gal (8.83 kWh/L) for gasoline. (see chart above) A flex-fuel vehicle will experience about 76% of the fuel mileage MPG when using E85 (85% ethanol) products as compared to 100% gasoline.
