Which region did Hubbert predict would experience the peak of oil production?

• A. The forty-eight contiguous United States
• B. The world
• C. The United States including Alaska
• D. Europe

Answer: (B)

Hubbert’s idea is that production of a finite resource follows a bell-shaped curve: it rises as easy-to-access oil is developed, reaches a maximum, and then declines as remaining reserves become harder and costlier to extract. He tested this with the United States, showing that U.S. oil output would eventually peak because the available easy oil would be tapped out and discovery would not keep pace with consumption. But the same logic applies when you look at oil worldwide. If you treat the planet’s oil as one large system, the total rate at which oil can be produced also reaches a peak and then declines as the cumulative supply of easily recoverable oil is exhausted and new discoveries can’t fully compensate. So the region that would experience the peak, from a global perspective, is the world as a whole, not a specific country or continent. The main point is that, for a finite resource, the production rate is not unlimited; it climbs, peaks, and then falls as remaining reserves dwindle.
