摘要: The latest energy crisis in early 2021 has further exposed the world’s high dependency on fossil fuels. Renewable energy, on the other hand, has seen a constant drop in its costs due to the improvement in technology and economic growth. Being more competitive, it has become a main driver for the green and low-carbon transition of economic growth in many countries around the world. The energy mix and power supply structure in the Southeast Asia are generally dominated by fossil fuels, especially in the coal power and gas power sector. Although renewable energy boasts good resource endowments, non-hydro renewable energy is still underdeveloped, and the development stage of Southeast Asian countries have seriously restricted the process of their green and low-carbon transition. Therefore, international cooperation will play an important role in their green and low-carbon development.This report summarizes the current status of energy transition globally and the actions taken by the international community. It then analyzes the low-carbon development status of the power sector in Southeast Asia, including the characteristics of power resource, power grids, low-carbon policies related to the power sector transition and international power investments in the region. On this basis, the study further identifies the opportunities and challenges in the process of lowcarbon transition of the power sector in Southeast Asia, and selects two typical countries, Indonesia and Vietnam, for an in-depth case study on the objective planning, transition obstacles and demands for international cooperation of the power sector in Southeast Asian countries …
