In addition, bio-energy with CCS (BECCS) power plant is needed to achieve the 2-degree target in 2050. â¢ Transport sector: The energy efficiency improvement will be achieved by behavioral changes, road surface improvement and engine performance improvement. Currently, the proportion of new efficient vehicle fleets is increasing, including hybrid, plug-in hybrid, and battery electric vehicles. Under Thailandâs LEDS, the transport sector needs to increase the energy efficiency to 68% of total final energy consumption in 2050. Though the share of energy efficiency improvement decreases, the energy consumption in the efficient vehicle increases. Liquid biofuels have been promoted as clean alternative fuels in the transport sector.
