World demand for oil is expected to increase 35% over the next 10 decades. In the US and Canada, total use of oil has actually declined over the past 20 years. Offer some possible explanations for these two opposite trends.

Under developed countries are rapidly becoming industrialized and use more oil. But they don't have the money to develop alternative energy.
