How long will our oil last?
GIVEN that the Earth’s endowment of oil is about 3 trillion barrels AND
GIVEN that current production is 85 million barrels a day
IF world consumption remains at this level
CALCULATE how many years we can continue to use oil.
GIVEN that the world population is 6.7 billion in 2010
IF world population rises to 9 billion by 2050
DRAW A GRAPH of the reduction in world oil use per capita 2010 to 2030
GIVEN that EU plans to be oil free by 2050
DRAW the EU reduction curve on the same graph as above.
