     The IEA's World Energy Outlook report says increasing demand and use of energy has to be limited.

     The switch to more low-carbon energy will require an extra investment (投资) of￡2.7 trillion-about 0.2%

of GDP-the IEA report said, with an average￡11 spent per head worldwide on more efficient cars, buildings

and so on. The improved energy efficiency would deliver fuel-cost savings of almost￡4.5 trillion.

     The report says that the world energy demand will grow by l.6% per year on average between 2006 and

2030. This figure is lower than planned last year because the economic slowdown has reduced demand.

Demand for oil will rise from the current 85 m barrels (桶) per day to 106 m barrels by 2030.

     Demand for coal will rise more than any other fuel-despite the environmental damage it causes-making up

more than a third of the increase in energy use.

     The report claims oil will remain the world's main source of energy for many years to come even with the

rapid development of altemative renewable energy technology but the amount of oil remaining, production

costs and consumer price will remain unpredictable.

     Mr. Tanaka, IEA executive director, said big international oil and gas companies would in the future have

limited chances to increase production while in contrast national companies are planned to make up about 80%

of the increase of both oil and gas production to 2030. 

     The report says measures to control CO₂ emissions (排放) will improve energy security by reducing global

fossil-fuel energy use but this would not alarm the world's major oil producers.

     "OPEC production will need to be 12 m barrels higher per day in 2030 than today. It is clear that the energy

departments will have to play the leading role in handling climate change," said Mr. Tanaka.
