 A world average of individual
car usage is about 12,334 miles per year, which translates into (12,334 miles / 365 days) =
33.8 miles per day, or 54.4 kilometers per day.
 A world average of gasoline mileage per car is 31.2 miles per gallon,
which translates into 50.2 kilometers per gallon, or 13.3 kilometers per liter.
 Therefore, the world average daily consumption of gasoline is:
(54.4 km/day) / (13.3 km/liter) = 4.09 liters per day per car.
 The average density of gasoline is 0.74 kilogram per liter.
 The world average daily consumption of gasoline, per car, is: 4.09 liters per day × 0.74 kilogram per liter =
3.027 kilograms per day per car, or 3,027 grams per day.
 The average energy released by the burning of gasoline is 45.8 kilojoules per gram, or 10.95 kilocalories per gram.
 The average global rate of gasoline energy consumption, per car, is:
(3,027 grams/day × 10.95 kilocalories per gram) = 33,146 kilocalories per day.
 An average person weighs 62 kilograms.
 To maintain his/her own weight, an average person needs 33 kilocalories per kilogram of body weight.
 Therefore, a constantweight average person consumes (62 kilograms ×
33 kilocalories/kilogram) = 2,046 kilocalories per day.
 Therefore, the ratio of vehicletoperson energy consumption is: (33,146 / 2,046) = 16.2.
 In terms of energy consumption, one (1) car is equivalent to
16 persons.
 There are approximately 8,037 billion
people in the world today (November 2022).
 At present (2022), there are approximately 1.446
billion cars in the world (2022).
 The people in the world burn (8,037,000,000 × 2,046 kilocalories/day)
= 16,444,000,000,000 kilocalories per day =
16,444 teracalories per day.
 The vehicles in the world burn (1,446,000,000 × 33,146 kilocalories per day) = 47,929,000,000,000 kilocalories per day = 47,929
teracalories per day.
 The total number of calories consumed daily by people and vehicles amounts to: (16,444 + 47,929) = 64,373 teracalories.
 This is equivalent to: (64,373,000,000,000 kilocalories per day / 2,046 kilocalories/day/person) =
31,463,000,000 equivalent
persons.
 The ratio between equivalent persons to actual persons is: (31,463,000,000 / 8,037,000,000) = 3.91
 Therefore, current use of fossil fuel [in car transportation]
amounts to an equivalent population which is about four (4) times larger than the actual value,
in terms of energy consumption and subsequent release
of carbon dioxide to the atmosphere.
