Cambodia has high potential for developing renewable energy resources. Even though the country has not attracted much international investment in renewable energy by 2020, the country serves as a model to learn from for other ASEAN countries in terms of conducting solar power auctions. To attract more investment in renewable energy, the government could improve renewable energy governance, adopt clear targets, develop an effective regulatory framework, improve project bankability and facilitate market entry for international investors. Cambodia is highly vulnerable to the negative effects of climate change and it is advised that the country focuses more on developing renewable energy as part of climate change mitigation measures.
