The term Peak Oil refers to the peak of the earth's oil production. This is the point at which oil production or our capacity to find oil reserves has reached it's limit.
In 2004, 30 billion barrels of oil were consumed worldwide, while only
eight billion barrels of new oil reserves were discovered.
Even though new discoveries are in decline, in the current Oil Market Report, the International Energy Agency (IEA) estimates that
global demand will continue to grow annually at an average of 1.8 to
2.0 million barrels per day (bpd) through 2010.
