Peak oil and Bakhtiari’s 4 phases of transition
“The four Transition periods (T1, T2, T3, and T4) will roughly span the 2006-2020 era. …The major palpable difference between the four Ts is their respective gradient of oil output decline — very small for T1, perceptible for T2, remarkable in T3, and rather steep for T4. In fact, this gradation in decline is a genuine blessing for those having to cope and adapt.”
– Dr. A.M.S. Bakhtiari, Iranian oil expert
