BTW Petrus, here’s a little mathamatics I put together. Check the math volumes to make sure they’re correct and feel free use them or correct any miscalulation for your book. Source links for the volumes are at the bottom of this page.
1 barrel of oil Volume: 42 gallons
Olympic Pool Volume: 648,000 gallons*
Olympic Pool Volume: ~15,428 barrels of oil equivalent
It’s estimated the current world uses 1000 barrels of oil per second
1000 bbl x 86,400 seconds in one day = 86,400,000 bbl of oil used by the world in one day.
86,400,000bbl / 15428bbl = 5,600 Olympic sized pools of oil used each day.
5,600 pools x 365 days in a year = 2,044,000 Olympic sized pools of oil is use by the world in one year.
Olympic Pool dimensions: 50m x 25m x (2m depth)**
1 meter = 3.2808399 feet
1 mile = 5 280 feet
Olympic pool length: 164 feet
Olympic pool width: 82 feet
Olympic pool depth: 6.5 feet
164 feet length x 2,044,000 Olympic pools = 335,216,000 feet in length
335,216,000 feet /5280 feet in a mile = 63,488 miles
If all Olympic pool equivalents of oil used in one year were lined up end to end, the pool would be 82 feet wide x 6.5 feet deep x 63,488 miles long.
The circumference of the world at the equator is 24,892 miles
63,488 / 24,892 = The Olympic pools lined up end to end would stretch 2.5 times around the world
The world uses ~31 billion barrels of oil per year (31,536,000,000 = 86,400,000 x 365)
86,400,000bbl/210bbl tank = 411,429 tanks of oil used each day
411,429 tanks x 365 days = 150,171,429 tanks of oil per year
Gallons of oil per year: 31,536,000,000 x 42 = 1,324,512,000,000
1.3 trillion gallons
“One inch of rain falling on a 160 acres delivers 4,344,680 gallons of water”***
1,324,512,000,000 gal per year / 4,344,680 = 304,858 inches
304,858 / 12 inches = 25,405 feet of oil equivalent volume on top of 160 acres
1 cubic mile (length x width x height) holds the volume of 1.1 trillion gallons
IEA: Oil demand is expect to 118,000,000 bbl in 2030. According to the IEA projects, allowing for depletion, it will take 200 million barrels per day from 2001-2030 to meet the expected demand. ****
118 million barrels per day equals:
43,070,000,000 barrels per year
7,648 Olympic pools per day
2,791,677 pools per year
86,711 miles of pools lain end-to-end
3.5 times around the world
34,696 feet on top of 160 acres
