  2. Pathways to 2050: What it is and what it is not This publication discusses future energy shifts inthe contextof a long term atmospheric concentration of CO2 of no more than550 ppm. The options discussed are not a scenario, but an illustrativehypothesis to gauge the extent of change needed in our energyinfrastructure and the impact that might have on industry. The publication is not an endorsement of any particularpathway, technology or specific atmospheric concentration target.

  8. One way of representing the challenge: The Kaya Identity The Kaya Identity breaks down the main driving forces for CO2 emissions into four factors, such that: CO2 emissions = people x (GDP/Person) x (energy/unit GDP) x (CO2/unit energy) X X Only four factors govern the outcome: Population Number of people Economic prosperity GDP per person Energy intensity Energy per unit of GDP (energy efficiency of the economy) Carbon intensity CO2 per unit of energy (reflects the emissions from energy production and use)

  12. What needs to happen in power generation? Milestones by 2025 Commercialized coal powergeneration with carbon capture and storage and have some 100 or more plants in operation globally; Gained full public acceptance of nuclear power as a viable zero-carbon power generation option and restarted long-term growth in this industry. Wind & others Solar EJ Biomass and waste Hydro Nuclear 100 Gas Oil 50 Coal with sequestration Coal without sequestration 0 2002 By 2050 • Natural gas is the largest fossil contibutor to electricity generation; • Hydropower more than doubles until 2050; • Wind, geothermal, wave and tidal power increase nearly 160-fold from 2002; • Coal use grows by 50% and half the generation capacity uses CCS. Electricity generation by fuel BAU 2025 Pathways 2025 Pathways 2050

  13. An important role for electricity BAU Pathways to 2050 60 50 40 30 20 10 0 2002 2025 2050 Shares of electricity in final energy consumption (%) Electricity use is already growing more quickly relative to other energy carriers due to: • Increasing numbers of electrical appliances; • Information technology; • Improvements in electrical applications and a substitution of fossil fuels in end use. Potential role of electricity in a carbon constrained world: • Most renewable technologies generate electricity; • A flexible energy carrier, which produces no emissions at point of use, and offers additional potential for carbon management if generated from low and zero-carbon sources.

  14. Industry and manufacturing: Wide portfolio of measures and options Energy use and emissions levels arerising in industryand manufacturingdue to: • Rising population levels; • Continuing economic growth (e.g., GDPper capita in Chinaincreases by morethan afactor of 7 until 2050). Emissions reduction measures: • Increase the deployment of currently bestavailable technologies (BATs) especially todeveloping countries; • Improve energy efficiency and fuelconservation; • Develop new low-energy and low-carbonintensive technologies; • Shift towards electricity and bio fuels.

  16. Developments in the Mobility Sector 120 100 80 60 40 20 0 Energy consumption in the mobility sector (EJ) Marine bunkers Aviation Rail transport Vehicles / Road transport Trends • Shift towards mass transportation, which is about seven times more efficient than a light duty vehicle; • Need to significantly increase the deployment of highly efficient and hydrogen vehicles; • Growing emissions in the aviation sector due to high demand and absence of a large-scale alternative to current conventional fuels.

  17. What has to change in road transport?

Megatrend shifts in buildings 2002 Pathways 2050 0.78 GtC (11%) 0.75 GtC (9%) 104 EJ (35%) 237 EJ (43%) Energy use, EJ (% of world total) Carbon emissions, GtC (% of world total) Energy consumption increases due to: Rising living standards; A growing service sector; The information economy; A shift from rural to urban living. Energy consumption and emissions can be reduced by: • Radical design; • Placement; • Efficient appliances; • New materials; • In-situ energy generation.

  19. Towards a zero-energy home Ventilated double skin facades to reduce heating and cooling requirements Wood as a building material withadvantageous insulation properties,which also stores carbon and isoften produced with biomassenergy Rooms that are not normally heated (e.g. a garage) serving as additional insulation Solar photovoltaic panels for electricity production and solar thermal panels for water heating Transparent design to reduce the need for lighting New battery technology for the storage of the electricity produced by solar panels Trees to provide shade and cooling in summer, and a shield against cold wind in winter “Low-E” glass coating to reduce the amount of heat absorbed from sunlight through the windows (windows with the reverse effect can be installed in colder climates) Heat pump systems that utilize the stable temperature in the ground to support air conditioning in summer and heating or hot water supply in winter

  20. The power of consumer choices Consumer choices as a cross-cutting trend affect all the other megatrends. Today: • Energy characteristics of goods and services hardly affect our consumer choices; • Lack of consumer awareness regarding energy and carbon issues. By 2050: • Society has understood that their choices affect the energy balance; • The energy impacts of our choices become completely transparent; • Products will have a low-energy and low-carbon value. The different choices we make today can significantly affect our carbon footprint Two families, two footprints (tons of carbon p.a.) Household 4.09 Car travel 2.20 Air travel 3.11 Waste 0.25 Total: 9.65 Household 0.20 Car travel 0.23 Air travel 0.32 Waste 0.10 Total: 0.85 Source: BP carbon Calculator

  21. 2050: What has happened? The industry and manufacturing sector has further improved its efficiency; The mobility sector has nearly doubled its vehicle efficiency, adapted a broader range of fuels, and balanced private and mass transportation; The building sector has significantly enhanced its energy efficiency to partly offset rising energy demand; Consumers are fully aware that their every day choices affect the energy balance. • The power sector supplies low-carbon electricity from a wide variety of energy sources. Electricity use has increased significantly;

Mobility: Around 375 million high-efficiency vehicles are on the road. Predominantly high efficiency vehicles with a wide fuel mix. EU-25: « Wind and others » being 10-15 times the 2002 level. « Wind and others » being the largest power generation source. China: Nuclear power capacity increases nearly 10-fold to 2002. Nuclear generation capacity as big as EU and North America combined today. Japan: Energy use per GDP unit has fallen from 7 MJ/$ to 4.2 MJ/$. Energy efficiency continues to improve by more than 2% a year. By 2025: By 2050: Examples
