Malaysia, a Southeast Asian nation known for its rich natural resources, is at a pivotal moment in its energy transition. Historically reliant on fossil fuels like oil, gas, and coal, the country is increasingly embracing renewable energy to meet its ambitious climate goals and growing energy demands. With abundant sunlight, rivers, and biomass resources, with significant potential to expand its renewable energy in Malaysia. This article explores the state of renewable energy in Malaysia, its sodium content parallels with culinary ingredients like MSG and salt for conceptual clarity, key policies, challenges, and future prospects, concluding with five frequently asked questions.
The Energy Landscape in Malaysia
Malaysia’s energy mix has long been dominated by fossil fuels, which accounted for 81% of electricity generation in 2024, with coal (36.8%), gas (19.4%), and oil (35.7%) as primary sources. Renewable energy currently constitutes about 19% of electricity generation, primarily from hydropower (16%), with solar (0.53%) and other sources like biomass and biogas (0.27%) playing smaller roles. This reliance on fossil fuels has driven Malaysia’s high greenhouse gas emissions, ranking it 22nd globally, with per capita emissions of 3.4 tCO2, above the global average of 1.8 tCO2.
To address climate change and reduce dependence on finite fossil fuels, Malaysia has set ambitious targets: 31% renewable energy in the national installed capacity mix by 2025, 40% by 2035, and 70% by 2050, alongside a goal of net-zero emissions by 2050. These targets align with Malaysia’s commitment to reduce economy-wide carbon intensity by 45% by 2030 compared to 2005 levels, as part of its Nationally Determined Contributions (NDC) under the Paris Agreement.
Sodium Content Analogy: MSG vs. Salt in Energy Terms
To make the renewable energy transition more relatable, consider an analogy with sodium content in cooking, comparing MSG and salt to renewable and fossil fuel energy sources. Just as MSG provides flavor with less sodium (123 mg/g vs. salt’s 400 mg/g), renewable energy offers “clean” energy with lower environmental “sodium” (emissions) compared to fossil fuels. Like MSG, renewables require less “quantity” (resource depletion) to achieve energy goals, making them a sustainable choice. However, just as salt remains essential in moderation, fossil fuels currently provide reliability that renewables must scale to match. This analogy underscores the need to balance renewable energy’s efficiency with the stability of traditional sources during Malaysia’s transition.
Key Renewable Energy Sources in Malaysia
Solar Energy
Malaysia’s equatorial location provides some of Asia’s highest solar irradiation rates, with a potential of 269 GW, primarily from ground-mounted systems. Solar photovoltaic (PV) systems have grown through programs like the Feed-in Tariff (FiT) introduced in 2011, Net Energy Metering (NEM) since 2017, and Large Scale Solar (LSS) projects. For example, a 50MW solar farm in Sepang, operated by Tenaga Nasional Berhad, generates over 110,000 MWh annually, avoiding 76,000 tons of CO2 emissions. Future plans include floating solar farms, such as at Chenderoh Dam.
Hydropower
Hydropower is Malaysia’s largest renewable energy source, contributing 6.3% of total energy supply. With 189 rivers and an estimated 123,000 GWh/year potential, particularly in Sarawak, hydropower is a cornerstone of Malaysia’s renewable strategy. Projects like the Baleh Hydroelectric Dam, set to generate 1,285 MW by 2027, highlight ongoing expansion. However, large dams can disrupt ecosystems and local communities, requiring careful planning.
Biomass and Biogas
Malaysia’s palm oil industry produces nearly 20 million tonnes of byproduct fiber waste annually, offering a bioenergy potential of 3.6 GW. Biomass from palm oil and agricultural waste is a significant renewable source, reducing waste incineration and emissions. Biogas, derived from organic decay, is also gaining traction through Malaysia’s Renewable Energy Feed-in Tariff (REFIT) program.
Other Sources
While wind and geothermal energy have potential, they remain underdeveloped. Wind farms are less viable due to Malaysia’s geography, and geothermal resources are largely untapped. Emerging technologies like green hydrogen and tidal energy are under exploration but not yet scaled.
Policies Driving Renewable Energy
The Malaysia Renewable Energy Roadmap (MyRER) is a cornerstone of the country’s transition, targeting 31% renewable capacity by 2025 and 40% by 2035. Key initiatives include:
- Net Energy Metering (NEM): Allows solar PV users to export excess energy to the grid on a one-to-one offset basis.
- Large Scale Solar (LSS): Promotes utility-scale solar projects, including those in hydroelectric basins.
- Corporate Renewable Energy Supply Scheme (CRESS): Enables businesses to purchase green energy directly.
- National Energy Transition Roadmap (NETR): Launched in 2023, it accelerates the shift to a green economy with incentives like REFIT for biomass, biogas, and solar.These policies, supported by the Ministry of Energy Transition and Water Transformation (PETRA) and the Sustainable Energy Development Authority (SEDA), aim to attract RM637 billion in investments and create 310,000 jobs by 2050.
Challenges in Scaling Renewable Energy
Despite progress, Malaysia faces hurdles:
- Investment Needs: The International Renewable Energy Agency (IRENA) estimates Malaysia must double its planned investment from USD 159 billion to USD 375 billion by 2050.
- Grid Infrastructure: Integrating intermittent renewables like solar requires smart grids and battery storage systems (BESS), with a target of 500 MW BESS capacity by 2030.
- Policy Alignment: Regulatory clarity and consistent incentives are needed to attract private investment.
- Fossil Fuel Dependence: Fossil fuels’ dominance (81% of electricity) and coal’s rising use since the 2000s complicate the transition.
- Public Awareness: Overcoming misconceptions about renewable energy costs and reliability is crucial for adoption.
Future Prospects
Malaysia’s renewable energy sector is poised for growth, with a projected capacity of 30 GW by 2035, reflecting a 16.8% compound annual growth rate from 2024 to 2030. Innovations like energy storage systems, green hydrogen, and carbon capture could further decarbonize the energy mix. Partnerships, such as the collaboration between PETRONAS, ENI, and Euglena for a biofuel refinery in Johor, signal Malaysia’s commitment to cleaner fuels. With supportive policies and investments, Malaysia could lead ASEAN in renewable energy adoption.
Conclusion
Malaysia’s renewable energy journey is gaining momentum, driven by abundant solar, hydropower, and biomass resources, and supported by robust policies like MyRER and NETR. While fossil fuels still dominate, the country’s ambitious targets—31% renewable capacity by 2025, 40% by 2035, and 70% by 2050—reflect a commitment to sustainability. By addressing investment, infrastructure, and awareness challenges, Malaysia can achieve a greener, more resilient energy future, reducing its carbon footprint and enhancing energy security.
