Las reservas y el consumo de petróleo

Interesante reflexión sobre la manera en que las reservas petroleras han ido aumentando con el paso del tiempo.

... In 1914, the Bureau of Mines said that U.S. oil reserves would be exhausted by 1924. In 1939, the Interior Department said that the world had 13 years' worth of petroleum reserves. Then a global war was fought, and the postwar boom was fueled. In 1951 Interior reported that the world had . . . 13 years of reserves. In 1970, the world's proven oil reserves were an estimated 612 billion barrels. By 2006, more than 767 billion barrels had been pumped, and proven reserves were 1.2 trillion barrels. In 1977, scold in chief Jimmy Carter predicted that mankind "could use up all the proven reserves of oil in the entire world by the end of the next decade." Since then the world has consumed three times more oil than was then in the world's proven reserves.
