How much oil is left?
The world’s total annual consumption of crude oil is one cubic mile of oil (CMO). The world’s total annual energy consumption – from all energy sources – is currently 3 CMO. By the middle of this century the world will need between 6 and 9 CMO of energy per year to provide for its citizens. In their new book, Hewitt Crane, Edwin Kinderman, and Ripudaman Malhotra introduce this brand new measuring unit and show that the use of CMO replaces mind-numbing multipliers (such as billions, trillions, and quadrillions) with an easy-to-understand volumetric unit. It evokes a visceral response and allows experts, policy makers and the general public alike to form a mental picture of the magnitude of the challenge we face.
