Oil Peak

Scientists use the term 'peak' to describe the point where half the world's original endowment of oil would be depleted. (That includes cumulative production, known reserves and reserves projected to be discovered.) After peak, world production of oil will slow down, and unless demand declines dramatically, price will continuously rise and supply disruptions will occur. This is likely to bring about economic and political turmoil as well as wars over the control of the remaining oil.
When will worldwide oil production peak? Experts are divided between optimists -- those who believe that oil production will peak in about 20-30 years-- and the pessimists -- those who argue that peak will come much sooner, in the first decade of this century.
