energy demand by sector
The future development pathways for Developing Asia’s primary energy demand are shown in Figure 6.95 for both the Reference and Energy [R]evolution Scenarios. Under the Reference Scenario, total primary energy demand more than doubles from the current 31,100 PJ/a to 67,400 PJ/a in 2050. In the Energy [R]evolution Scenario, a much smaller 40% increase in consumption is expected by 2050, reaching 43,800 PJ/a.
Under the Energy [R]evolution Scenario, electricity demand is expected to increase disproportionately in Developing Asia (see Figure 6.96). With the introduction of serious efficiency measures, however, an even higher increase can be avoided, leading to electricity demand of around 1,965 TWh/a in 2050. Compared to the Reference Scenario, efficiency measures avoid the generation of about 860 TWh/a.
Efficiency gains in the heat supply sector are also significant (see Figure 6.97). Compared to the Reference Scenario, consumption equivalent to 2,900 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 rise to 8,300 PJ/a by 2050, saving 90% compared to the Reference Scenario.
