Renewable energy, often referred to as clean energy is derived from natural resources and does not deplete when used. Malaysia targets to achieve 31 % renewable energy generation by 2025. The availability and reliability of renewable energy resources are highly vulnerable to climate conditions. Floods, which account for almost 40 % of natural disaster can adversely affect energy resources generation, transmission and infrastructure. Malaysia as a tropical country is especially prone to floods due to the high average rainfall it receives annually. Malaysia energy policy planning has placed more emphasis on efficiency of generation and emissions reductions. The need to adapt to flood disasters and other climatic change challenges has not been adequately addressed. Due to the flood risk in Malaysia, adaptation to climate change and disasters such as flood needs to be considered in Malaysia's energy policy planning. This paper reviews scholarly papers and news articles related to the flood phenomenon in Malaysia, and analyses the impact of flood disasters on renewable energy generation and energy policy planning in this country. The findings indicate that flood has an insignificant effect on Malaysia's renewable energy power generators as they are not located in flood-prone areas. The east coast of Peninsular Malaysia, which is exposed to flooding during the monsoon season, is the most vulnerable to flood disasters. Most renewable energy generation facilities including biomass power stations, hydropower, and solar panels are located on the west coast of Peninsular Malaysia, and in Sabah and Sarawak. The potentially high risk of flash floods and unpredictable climate conditions in Malaysia should not be underestimated and must be duly considered.
