Member states set a renewables target of 23 percent of the region’s fuel mix by 2025. They also agreed to cut greenhouse gas emissions by 20 percent over the next decade. In fact, most of the ASEAN member states have already set their own target for renewable energy. These include Malaysia with a target of 4 GW by 2030; Singapore with 350 MW of Solar PV by 2020; Indonesia with 23 percent of the total energy mix in 2025; and the Philippines with 15 GW in 2030.
This is a big challenge, given ongoing regional growth rates of around 4.9 percent since 2014. This means that the region’s ongoing energy demand is forecast to jump by over 80 percent between 2013 and 2035. A rise equivalent to Japan’s current energy use.
How much renewable potential is there?
This region has a huge potential for renewables, but it is largely unexploited, reports the IEA. In fact, Indonesia and the Philippines have great geothermal potential, with current estimates for Indonesia put at 28,807 MW, or around 40 percent of the total geothermal resources worldwide.
As for hydropower, Vietnam, Cambodia, Laos and Myanmar have huge potential, some 30,000 MW in Lower Mekong Basin alone.
Situated in the tropics, all countries in the region enjoy good solar potential with average daily solar radiation of 4500 kWh m2 and abundant sunshine for about 12 hours day. Read more https://www.eniday.com/en/sparks_en/green-south-east-asia/
