Vision 2050 The Change to a Sustainable Energy Path By Gunnar Boye Olesen, Emil Bedi & Ann Vikkelsoe INFORSE-Europe Article on Vision 2050 at www.inforse.org International Network for Sustainable Energy – Europe is a network of 55 NGOs. INFORSE-Europe is supported by EU Commission DG Environment, Danish Open Air Council and others Sustainable Energy for Europe – INFORSE-Europe seminar – Brussels 27-28 November 2002 Vision 2050 - Background The world energy system: is beyond the environmental limits does not provide basic energy needs as light and healthy cooking facilities to 2 billions of the world’s population To avoid dangerous climate change we must limit global warming to 1ºC in the 21st Century We should provide all with basic energy needs and allow developing countries to develop, including use of cheap energy supply INFORSE International Network for Sustainable Energy Environmental Limit: Climate Change To be sure to keep global warming below 1ºC century, we must limit global CO2 emissions to about 250 Gigaton of Carbon in 21st century = 35 years of current consumption (assumed climate sensitivity of 3.5ºC) The climate sensitivity is commonly accepted to be in the range of 2 to 5ºC with an average of 3.5ºC.

Technology learning can drive prices down. One exception is houses. In EU houses could use only 1/7 of todays heat demand in 2050. This will require renovation/re-building of 2% p.a. / heat consumption 20-40 kWh/year per m2 For transport is expected increase in efficiency from todays 15-20% to 50%, and re-gain of “break energy”. Hydrogen and fuel cells as solutions together with electrical driven vehicles. Energy service demand will increase, also in industrialized countries, energy demand decrease.

Some sites give cost-effective electricity today. Solar: PV could reach 500 MWpeak in 2003, and then grow 25% pr. year Biomass and hydro: Increase 30-50% in total Biomass can be used as transport fuel INFORSE International Network for Sustainable Energy Gigawatt continues consumption Renewable Energy Potential 10000 9000 8000 52200 GW Solar centrals 7000 6000 PV on houses Biomass 5000 Hydro 4000 3000 Windpower on farmland Wind, off-shore etc. 2000 1000 0 Potential Scenario INFORSE International Network for Sustainable Energy Electricity - Worldwide (TWh/y) 25000 20000 Nuclear 15000 Fossil tot.

INFORSE International Network for Sustainable Energy More on Infrastructure decentralised power production, to use local renewables and to cover heat demand (CHP) more investments in demand-side efficiency, less in energy supply, after transition phase 2000-2030 gas demand stable until 2025, then decline hydrogen – fuel cell systems for transport and to replace gas where local renewables insufficient some gas networks can be used for hydrogen heat networks to remain in densely built areas INFORSE International Network for Sustainable Energy Vision 2050 simple spread-sheet model Based on energy balance Trends for RE-supply, energy consumption, other fuels 1990-2050. 2000 base year. 10-years interval 2002 Denmark, Slovakia and EU 2003 Hungary, Romania, Belarus (probably) TABLE 1 Fuel Oil products Coal & Coke Year 2000 Orimul- PJ Crude oil sion Primary Production Klimakorrektion (forbrug) Refineries (conversion to end products) Import / export (incl. bunkring and international flights) Net storage, reuse and statistical difference Total Net supply Oil, coal and gas sector Exploitation own consumption, flaring Refinaries own consumption Electricity and District heating stations District heating sector Geothermal stations Condensing power stations Cogeneration stations RE (solar, wind, hydro, wave, tidal) Hydrogen Grid losses etc. Final Energy consumption Non-energy purposes Transport Road Rail Domestic aviation Navigation Defense Production Farming etc. Manufacturing Construction Service sector Private Public Housheholds Final Energy consumption - total, ex. non-energy Total Consumption Specific CO2-emissions (ton CO2/PJ) 2), 3), 4), 5) CO2-emissions (million ton CO2) TABLE 4 Consumptions parameters Heated floorspace6) / Production mill. m2 Private service 49,9 Public service 38,9 Households 1 (multifamily) 77,4 Households 2 (detached) 165,0 8) Farming, etc. Manufacturing8) Construction Total 8) Petrocoke Diesel+ Fueloil+ heating waste oil oil Petrol+ kerosene Jet fuel Refinary Other oil gas products LPG 764,53 0,86 - 346,27 - 416,62 - 1,64 - 0,00 33,54 0,61 35,01 5,67 1,12 6,79 0,57 69,78 - 61,31 11,05 20,09 5,15 139,19 9,26 1,97 155,57 0,01 99,76 - 14,89 2,97 87,85 21,59 - 18,56 0,06 3,09 Natural gas 1) 0,08 8,06 - 4,66 0,10 3,58 0,05 15,56 15,61 0,25 23,35 - 1,50 22,09 13,63 10,07 3,53 310,30 6,59 158,43 7,49 169,45 - 120,68 - 3,11 193,10 25,03 35,01 1,27 1,60 1,09 0,04 2,83 0,33 4,55 0,05 0,31 20,30 136,67 0,01 90,89 1,98 0,15 12,03 68,66 3,08 1,51 0,01 6,76 35,01 80.000 2,80 Factor 100 100 100 100 0,01 0,01 0,01 6,79 6,79 92.000 0,62 2,03 8,34 0,04 0,26 0,12 0,04 12,34 20,09 78.000 1,57 3,37 0,37 24,62 8,95 6,39 3,38 2,00 33,29 154,10 155,56 74.000 11,51 86,08 0,01 0,05 0,00 0,00 0,14 0,10 0,03 0,02 0,01 1,40 87,85 87,85 73.000 6,41 0,53 1,94 1,16 3,09 3,09 73.000 0,23 0,23 1,83 0,17 0,06 0,06 0,70 3,58 3,58 65.000 0,23 1,23 11,16 15,61 56.900 0,89 22,09 0,05 12,43 169,45 95.000 16,10 3,81 33,46 0,21 4,29 2,09 30,33 74,19 193,10 56.900 10,99 Share Specific Net Heat Fin. heat Share gas, coal, Share Share Share Share consumption consump Heat.
