WORLD ENERGY [R]EVOLUTION A SUSTAINABLE WORLD ENERGY OUTLOOK africa GLOBAL SCENARIO OECD NORTH AMERICA LATIN AMERICA OECD EUROPE AFRICA MIDDLE EAST EASTERN EUROPE/EURASIA INDIA NON OECD ASIA CHINA OECD ASIA OCEANIA africa: energy demand by sector The future development pathways for Africa’s energy demand are shown in Figure 5.57 for the Reference and the Energy 5 [R]evolution scenario. Under the Reference scenario, total primary energy demand in Africa increases by 104% from the current 27,681 PJ/a to 56,500 PJ/a in 2050. In the Energy [R]evolution scenario, by contrast, energy demand increases by 53% compared to current consumption and it is expected by 2050 to reach 42,300 PJ/a. Under the Energy [R]evolution scenario, electricity demand in the industrial, residential, and service sectors is expected to increase disproportionately (see Figure 5.58). With the exploitation of efficiency measures, however, an even higher increase can be avoided, leading to 2040 TWh/a in 2050. Compared to the Reference case, efficiency measures in industry and other sectors avoid the generation of about 500 TWh/a or 22%. In contrast, electricity consumption in the transport sector will grow significantly, as the Energy [R]evolution scenario introduces electric trains and public transport as well as efficient electric vehicles faster than the Reference case. Fossil fuels for industrial process heat generation are also phased out more quickly and replaced by electric heat pumps and hydrogen. Efficiency gains in the heat supply sector are larger than in the electricity sector. Under the Energy [R]evolution scenario, final demand for heat supply can even be reduced significantly (see Figure 5.60). Compared to the Reference scenario, consumption equivalent to 4,820 PJ/a is avoided through efficiency measures by 2050. In the transport sector it is assumed under the Energy [R]evolution scenario that energy demand will increase from 3,301 PJ/a in 2009 to 4,440 PJ/a by 2050. However this still saves 37% compared to the Reference scenario. By 2030 electricity will provide 4% of the transport sector’s total energy demand in the Energy [R]evolution scenario increasing to 20% by 2050. figure 5.57: africa: total final energy demand by sector under the reference scenario and the energy [r]evolution scenario (‘EFFICIENCY’ = REDUCTION COMPARED TO THE REFERENCE SCENARIO) 40,000 35,000 30,000 35,000 20,000 15,000 10,000 5,000 PJ/a 0 • ‘EFFICIENCY’ •OTHER SECTORS • INDUSTRY TRANSPORT 118 REF 2009 E[R] REF E[R] 2015 REF E[R] 2020 REF E[R] 2030 REF E[R] 2040 REF E[R] 2050 key results | AFRICA - DEMANDPDF Image | SUSTAINABLE WORLD ENERGY OUTLOOK
