World Energy Outlook 2007

Fossil fuels – oil, natural gas and coal – remain the dominant sources of
primary energy worldwide in the Reference Scenario (Figure 1.1). They
account for 84% of the overall increase in energy demand between 2005
and 2030. Their share of world demand rises from 81% in 2005 to 82%
in 2030. Oil remains the single largest fuel, though its share falls from
35% to 32%. The share of coal rises from 25% to 28%, and that of
natural gas from 21% to 22%. The rise in fossil-energy use drives up
related emissions of carbon dioxide by 57% between 2005 and 2030
(see Chapter 5).

Coal sees the biggest increase in demand among all primary energy sources in
absolute terms between 2005 and 2030, closely followed by natural gas and oil
(Figure 1.2). Coal demand jumps by 38% between 2005 and 2015 and 73%
by 2030 – a faster increase than in previous editions of the Outlook. Nuclear
power accounts for most of the fall in the share of non-fossil primary fuels,
dropping from 6% of total primary energy demand in 2005 to 5% in 2030.
There is no change in the share of hydropower, at 2%, and the share of biomass
and waste falls slightly, from 10% to 9%. The share of other renewables, a
category that includes wind, solar, geothermal, tidal and wave energy, rises
from less than 1% to about 2%.
