Summary of IEA Scoreboard 2009

• IEA member countries have significantly diversified their energy mix over the past 35 years, reducing dependence on oil while increasing the use of natural gas, nuclear energy, and renewables.
• Despite this, IEA members remain major global energy importers, with oil accounting for the largest share of imports, although the overall combined share has decreased.
• Decoupling of energy consumption from GDP growth is evident, achieved through shifts in economic structure, increased energy efficiency, and the growth of the service sector.
• Energy intensity has declined for most IEA countries, reflecting efficiency improvements, though gains slowed after the 1990s due to lower energy prices.
• Nuclear energy expanded rapidly in the 1980s but growth slowed, still contributing to diversification. Renewables, particularly wind and solar, have seen explosive growth in recent decades.
• CO₂ emissions from fuel combustion have increased in the IEA, despite energy efficiency gains, driven by fossil fuel use, especially oil and coal. However, emissions per GDP have decreased significantly.
• Global energy demand has grown rapidly, with non-IEA countries contributing increasingly to supply and consumption, widening regional disparities.
• Challenges include sustaining efficiency gains, managing energy security, and accelerating decarbonization to meet climate goals, with IEA member countries leading in policy frameworks but facing limited RD&D funding and transparency issues.
