  5. Energy Trends in Reference Scenario Over 70% of this increase comes from developing countries. Global Primary Energy Demand is pejected to increase by 53% between 2004 and 2030 (average annual rate of 1.6%). The power generation sector contributes close to one-half of the global increase. Demand grows by one-quarter in the period to 2015 alone. The increase in demand amounts to almost 6 billion toe, or 53% of current demand. 5

  9. Energy Trends in Alternative Scenario § World primary energy demand in 2030 is about 10%, or 1 690 Mtoe, lower in the Alternative Policy Scenario than in the R S § The impact of new policies is felt throughout the period § In 2015, the difference between the two scenarios is 4%, or 534 Mtoe § The policies analysed halt the rise in OECD oil imports by 2015 9

  10. Energy Trends in Alternative Scenario § OECD countries and developing Asia become more dependent on oil imports in 2030 compared to today, but markedly less so than in the R S § Global oil demand reaches 103 mb/d in 2030 in the Alternative Policy Scenario – an increase of 20 mb/d on 2005 levels but a fall of 13 mb/d in the period § Gas demand and reliance on gas imports are also reduced below the levels of the Reference Scenario 10

  12. Energy-related CO2 emissions are cut by 6.3 Gt, or 16%, in 2030 relative to the Reference Scenario and already 1.7 Gt, or 5%, by 2015. Energy Trends in Alternative Scenario § CO2 EMISSION § OECD emissions peak by around 2015 and then decline. § Emissions in Japan and the European Union in 2030 are lower than 2004 levels. Global emissions nonetheless continue to rise, from 26 Gt in 2004 to 32 Gt in 2015 and 34 Gt in 2030. § 12

  15. Energy Trends in Alternative Scenario Why an Alternative Policy Scenario? The Alternative Policy Scenario analyses how the global energy market could evolve if countries were to adopt all of the policiesrelated to energy security and energy-related CO2 emissions. - to improve efficiency in energy production and use to increase reliance on non-fossil fuels to sustain the domestic supply of oil and gas within net energy- importing countries The aim is to understand how far those policies could take us in dealing with these challenges and at what cost. THE POLICIES INCLUDE EFFORTS: 15

  16. Energy Trends in Alternative Scenario THE MAIN POLICY MEASURES came into operation in • January 2005:the EU Greenhouse Gas Emissions Trading Scheme • February 2005: the Kyoto Protocol • January 2006: the Asia-Pacific Partnership on Clean Development • and Climate (AP6) • March 2006: the European Commission Green Paper addressing • energy security (EC, 2006) • May 2006/Japan: New National Energy Strategy on energy security 16

  24. Energy Trends in Alternative Scenario Technological Developments ENERGY EFFICIENCY ONLY Technologies that have yet been demonstrated on a commercial basis are included in the Alternative Policy Scenario POTENTIAL IMPACT OF BREAKTHROUGHS • Carbon Capture and Storage • Second-generation biofuels • Plug-in hybrids and other advanced technologies 24

  25. Energy Trends in Alternative Scenario POTENTIAL IMPACT OF BREAKTHROUGHS • The introduction of CCS in the power sector would reduce emissions by 2Gt in 2030 • 3 100 TWh of electricity would then be generated from coal and natural gas plants equipped with CCS • Some 70% of new coal-fired capacity and 35% of new gas-fired plants would be equipped with CCS over the projection period • CCS in coal plants would account for more than 80% of the captured emissions. CARBON CAPTURE AND STORAGE 25

  26. Energy Trends in Alternative Scenario POTENTIAL IMPACT OF BREAKTHROUGHS • Enzymatic hydrolysis • Gasification of woody ligno-cellulosic feedstock • Integration of biomass gasification and combined-cycle technology SECOND-GENERATION BIOFUELS 26

  27. Biofuels use in road transport would double Energy Trends in Alternative Scenario POTENTIAL IMPACT OF BREAKTHROUGHS • Salesof hybrid vehicles would make up 60% of new light-duty vehicles sales PLUG-IN HYBRIDS AND OTHER ADVANCED TECHNOLOGIES • Plug-in hybrids would enter the LDV market in comparaison to the Alternative Policy Scenario those measures combined would avoid the combustion of more than 7 mb/d of oil, saving 1 Gt of CO2 in 2030 27

  32. Investments in Energy Supply Infrastracture/EuE In Reference Scenario -4 • The stated prices must be high enough to stimulate sufficient investment in new supply infrastructure • Many factors may impede required investments: • a worsening of the investment climate • changes in government attitudes to foreign investment • changes in capacity expansions • the adoption of more stringent environmental regulations • less favourable licensing and fiscal conditions 32

  33. Investments in Energy Supply Infrastracture/EuE In Alternative Scenario -1 • The reductions in energy demand, energy imports and energy- related CO2 emissions induce different investment pattern: • Consumersinvest more to purchase energy/efficient equipments • Energy suppliers/producers invest less in new energy- production and transport infrastructure • Over 2005-2030, the investment required by the energy sector – ranging from end-use appliances to production and distribution is $560 billion less (in year-2005 dollars) than in Reference Scenario 33
