The End of Oil?

Deffeyes has no doubt that by 2019, the year in which Hubbert’s theories indicate global oil production will drop to 90 percent of current rates, human ingenuity will have found replacement energy sources (see “What Energy Crisis?”, p. 19). But Deffeyes is optimistic about the long term only because he believes that by 2010, pressures will grow so intense that they’ll create the resolve necessary to develop a new energy ­economy. In the short term, he foresees continually rising oil prices that force industry after industry closer to the wall. He fears not just escalating resource wars around the world but also mass starvation in some countries, since the 6.4 billion people living on the earth today are fed thanks largely to the successes of the 20th century’s “green revolution,” which, among other innovations, brought petrochemical-based fertilizers into wide use.
