The development of renewable energy in Southeast Asia has shown significant progress in recent years, along with increasing awareness of the importance of sustainability and climate change mitigation. Countries in the region, including Indonesia, Malaysia, Thailand and the Philippines, have adopted various policies and initiatives to utilize renewable energy sources such as solar, wind, hydro and biomass power. One of the main achievements in Indonesia is the floating solar power plant (PLTS) project on Lake Toba, which is expected to produce clean energy and reduce carbon emissions. Apart from that, geothermal projects on the island of Sumatra continue to develop because Indonesia is one of the countries with the largest geothermal potential in the world. Malaysia has also demonstrated commitment through the National Renewable Power Plan, which aims to achieve 20% of total renewable energy capacity by 2025. Investment in solar power technology continues to increase, with many private companies collaborating to increase infrastructure and production capacity. Thailand is a pioneer in renewable energy with an attractive Feed-in Tariff program for investors. The country also targets to get 30% of its energy from renewable sources by 2036. Wind power projects in Nakhon Ratchasima district are gaining widespread attention, contributing to the diversification of energy sources. The Philippines is committed to expanding the use of renewable energy under the Renewable Energy Act policy. Large solar projects such as those in Negros and Leyte have succeeded in generating significant power, supporting the country’s target of increasing the ratio of renewable energy in its energy mix. Issues related to regulation and investment remain a challenge, but the region is increasingly optimizing support from various international institutions. Southeast Asian cooperation through ASEAN forms a platform for sharing knowledge and technology, as well as supporting a sustainable energy transition. Climate change is pushing ASEAN countries to formulate ambitious targets, in line with the Paris Agreement. Various studies show that adopting renewable energy technology can not only help reduce emissions but also create new jobs and strengthen the local economy. At the local level, community initiatives are also starting to grow. Many villages in Indonesia and the Philippines have switched to renewable energy solutions, such as biogas from agricultural waste, which supports sustainability and provides economic benefits to communities. Through the implementation and development of renewable energy, Southeast Asia is committed to creating a more environmentally friendly and long-lasting energy ecosystem. Infrastructure improvements, foreign investment and collaboration between countries are expected to further accelerate the transition towards a sustainable energy future.
