*5.2. Final Energy Consumption in the Mekong Subregion*

In the total final energy consumption (TFEC), industry accounts for the largest share, followed by transportation, and other commercial and residential sectors, as Figure 2 shows. Energy consumption in the industrial sector is expected to increase from 68 Mtoe in 2017 to

217 Mtoe for the BAU scenario and to 184 Mtoe for the APS by 2050. Energy consumption in the transport sector is predicted to increase from 48 Mtoe in 2017 to 160 Mtoe for the BAU scenario and to 104 Mtoe for the APS by 2050. For other sectors, including the commercial and residential sectors, energy consumption is expected to increase from 46 Mtoe in 2017 to 105 Mtoe for the BAU scenario and to 89 Mtoe for the APS by 2050. The nonenergy sector (naphtha) is also used in the TFEC, especially for the refinery and petrochemical industries, with its use remaining the same for the BAU scenario and the APS in 2050.

Energy saving is expected to be highest for the transportation sector at 35.2%, 15.2% for the industrial sector, and 15.0% for the commercial and residential sectors, as indicated in Figure 2. The reduction in energy consumption in the final energy sector will derive from fuel efficiencies in the transportation, industry, commercial, and residential sectors (e.g., the introduction of more efficient heat and power, a shift to electric vehicles, hybrid and fuel cell vehicles, more efficient electric appliances, and energy-saving buildings).
