Yes. OPEC forecasts that oil demand will continue to grow strongly and oil will remain the world's single most important source of energy for the foreseeable future.

OPEC forecasts that oil's share of the worldwide energy market will fall from almost 40 per cent in 1995 to less than 37 per cent in 2020.

But oil will still be the world's single largest source of energy.

The reduction in oil's market share is largely due to the stronger growth enjoyed by other forms of energy, particularly gas.

The amount of oil demanded worldwide is actually expected to rise, from around 70 million barrels per day in 1995 to about 100 million barrels per day in 2020.
