The metabolic cost of transport includes the basal metabolic cost of maintaining bodily function, and so goes to infinity as speed goes to zero. [1] A human achieves the lowest cost of transport when walking at about 6 kilometres per hour (3.7 mph), at which speed a person of 70 kilograms (150 lb) has a metabolic rate of about 450 watts .

Variable or running costs are those that depend on the use of the car, like fuel or tolls. [7] Compared to other popular modes of passenger transportation, especially buses or trains, the car has a relatively high cost per passenger-distance traveled. [8] For the average car owner, depreciation constitutes about half the cost of running a car. [9]
Of the annual running costs of a car for an average person, 70–75% [9] are fixed costs (with respect to distance travelled): a 10% increase or decrease in usage should result in a 2.5–3% increase or decrease in annual running costs. Some of the annual running costs of a car, which are important in the economics of ownership, concern the ...
To calculate the cost, EV owners should grab their most recent electricity bill and look for the cost per kilowatt hour, or kWh. This cost can range from $0.09 to $0.35, but the national average ...
The miles per gallon equivalent cost of an alternative fuel vehicle can be calculated by a simple formula to directly compare the MPG operating costs (rather than the energy consumption of MPGe [7]) with traditional vehicles since the cost of resources varies substantially from region to region. [5] [4] For reference, the complete equation is:
Passenger transportation by rail systems requires less energy than by car or plane (one seventh of the energy needed to move a person by car in an urban context, [45]). This is the reason why, although accounting for 9% of world passenger transportation activity (expressed in pkm) in 2015, rail passenger services represented only 1% of final ...
Poolbeg Generating Station, a fossil gas power station owned by the semi-state electricity company, the ESB Group. Ireland is a net energy importer. Ireland's import dependency decreased to 85% in 2014 (from 89% in 2013). The cost of all energy imports to Ireland was approximately €5.7 billion, down from €6.5 billion (revised) in 2013 due mainly to falling oil and, to a lesser extent, gas ...
The energy cost of running between individuals is extremely variable, even when normalized for body mass. This suggests that a variety of other factors must influence the energy cost of running. The apparent individual variability of energy expenditure during running spurred the development of the concept of economy.
