Nobuo Tanaka Executive Director International Energy Agency The Alliance to Save Energy Washington , 25 September 2008 International Policy Leaders Dialogue on Energy Efficiency: Cost-Effective Carbon Reduction
A New Energy Revolution…. Cutting Energy Related CO 2 emissions Improved efficiency and decarbonising the power sector could bring emissions back to current levels by 2050. To ac hieve a 50% cut we would also have to revolutionise the transport sector.
To bring emissions back to current levels by 2050, a CO 2 incentive of $50/t is needed Reducing emissions by 50% would require a $200-$500/t incentive Marginal cost of cutting CO 2 emissions High Estimate Low Estimate End-use efficiency Transport alternative fuels Power Sector Industry fuel switching &CCS
The IEA‘s 25 Energy Efficiency recommendations to the G8 offer h uge CO 2 savings potential Global implementation of recommendations could save around 8.2 GtCO 2 /yr by 2030. Equivalent to 20% of global reference scenario energy related CO 2 emissions in 2030. WEO 2007 Projection
Examples of Global Savings from IEA Energy Efficiency Recommendations Recommendation Exajoules 2030 Mt CO2 2030 Building Codes for New Buildings 4.7 - 7.0 203 - 305 Mandatory Appliance Standards and Labels 7.6 – 10.9 1332 - 1903 Low power modes for electronic equipment 2.5 – 3.0 437 - 525 Incandescent light bulb phase-out 3.3 – 4.3 N/A Fuel Efficient Tyres for automobiles 2.8 – 4.7 180 - 300
The IEA‘s Energy Efficiency recommendations: Scorecards of implementation Lighting Transport Buildings Appliances Industry Cross-sectoral Full implementation Partial implementation Implementation Planned Investigation underway/ not implemented All recommendations
Energy Indicators - Tracking Trends & Identifying Potentials : The Example of Iron & Steel Adoption of best practice technologies in industry could save 1.9 – 3.2 Gt of CO 2 per year. The global technical potential in the iron and steel sector is 360 Mt of CO 2 per year, with the largest savings from blast furnace improvements
