Member states of the Association of Southeast Asian Nations (ASEAN) intend to reduce regional energy intensity 20 percent by 2020 and 30 percent by 2025 compared with 2005 levels. According to the ASEAN Centre for Energy (ACE), the region is on track to reach its goals as energy intensity levels have seen a downward trajectory between 1995 and 2014. Nevertheless, future projections like these still require concentrated efforts to ensure they are realised.
In tandem with a renewable energy policy, energy efficiency will be key to building a reliable and sustainable energy system for the future of Southeast Asia. Energy efficiency refers to the reduced rate of energy consumption in order to produce the same amount of output.
