Outlook
2006
|
World Marketed Energy Consumption by Fuel |
-
In the IEO2006 reference case, world energy consump-tion is projected to increase by 71 percent between 2003 and 2030, rising to 722 quadrillion British thermal units (Btu).
|
-
Oil remains the dominant energy source worldwide through 2030, though higher world oil prices in this year’s IEO means that the oil share of total energy use declines from 38 percent in 2003 to 33 percent in 2030, as other fuels replace oil where possible.
-
Coal use increases by 2.5 percent per year over the projection, while natural gas use grows by 2.4 percent per year.

World Marketed Energy Use: OECD and Non-OECD

|

Transportation Energy Use: OECD and Non-OECD

|
-
Higher world oil prices slow projected demand growth in the transportation sector, which oil continues to dominate.
-
Transportation energy use expands most quickly in the non-OECD, at 2.3 percent per year between 2003 and 2030, compared to only 0.9 percent per year in the OECD.
|
|
World Oil Consumption and Production by Region

-
Despite higher world oil prices, projected world oil demand increases by 48 percent between 2003 and 2030.
|
-
OPEC members are expected to provide 15 million barrels per day of the increase; but higher oil prices cause a substantial increase in non-OPEC supplies which rise by 24 million barrels per day, including 8 million barrels per day of unconventional liquids.
-
Unconventional resources (including oil sands, bitumen, biofuels, coal-to-liquids, and gas-to-liquids) account for about 10 percent of the world’s total liquids supply in 2030.

World Electricity Generating Capacity by Fuel
|
-
In the IEO2006, worldwide installed generating capacity expands from 3,710 gigawatts in 2003 to 6,349 gigawatts in 2030.
-
Natural gas and coal are expected to account for nearly 74 percent of the total world increment of electricity generating capacity over the projection period.
