Review of the policies and development programs for renewable energy in Malaysia: Progress, achievements and challenges

In 2022, Malaysia was ranked 28th worldwide in terms of its energy oil consumption. Energy consumption in Malaysia has been predominantly reliant on natural gas and coal in both the past and present. Oil and gas in Malaysia are predicted to be depleted in 14 years due to the high energy consumption, especially from petroleum sources. Thus, the Malaysian government aims to expand renewable energy (RE) in the country's energy mix as an alternative source of energy. As of 2022, Malaysia has generated roughly 2% of its electricity from various renewable sources, which is still far from the initial target of reaching 20% RE penetration by 2030. However, since 2017, RE has started to contribute to energy mix generation. Several policies, including an act, have been implemented in Malaysia to achieve the target in RE, but many challenges and difficulties have hindered the progress. Thus, the present study explored the current status and challenges for RE in Malaysia and discussed the effectiveness of the available energy policies and programs. The outcomes are potentially valuable to Malaysian policymakers, industries and researchers to improve their current practices for achieving the initial national RE target by 2030 as well as to move forward towards net zero emissions by 2050. This study provides a crucial roadmap for Malaysia to achieve its RE objectives and contribute significantly to the international transition towards a more environmentally friendly and sustainable future.
