In 2023, Malaysia's electricity consumption is markedly dominated by fossil fuels, accounting for over 80% of the total energy mix. Coal and gas are the primary contributors within this category, with coal generating approximately 43% and gas contributing nearly 37%. Meanwhile, low-carbon or clean energy sources comprise just over 19% of the electricity supply, with hydropower leading this segment at about 17%. Solar energy trails behind, making up less than 2% of the total. This heavy reliance on fossil fuels raises environmental concerns, as it significantly contributes to climate change and air pollution, highlighting the need for a transition to more sustainable energy sources.
To increase low-carbon electricity generation, Malaysia could learn from countries that have successfully integrated green energy into their grids. For instance, Denmark, a leader in wind energy, generates nearly 60% of its electricity from this source. This demonstrates the potential of wind power, even for a country with limited land area. Additionally, Greece's example of generating over 20% of its electricity from solar energy showcases what can be achieved with ample sunlight, a resource Malaysia also has in abundance. Furthermore, nuclear energy has played a significant role in various nations; France generates 68% of its electricity from nuclear power, setting a benchmark for nuclear advancement. Malaysia can take inspiration from these countries by diversifying its energy mix to include a larger share of wind, solar, and potentially nuclear energy, thereby reducing its dependency on fossil fuels.
Historically, Malaysia's journey with low-carbon electricity has been mostly centered around hydropower development, with fluctuations over the years. In the mid-1980s, there were modest increases, followed by a significant decline in the 1990s. However, from the late 1990s onward, hydropower development gained momentum with substantial growth, particularly noteworthy in 1999 and the 2010s, reaching a peak increase of around 6-7 TWh from 2016 to 2017. The last few years also saw a rise in hydropower, alongside the emergence of solar energy, which saw its debut in 2019 with a modest contribution of 0.8 TWh. These developments set a foundation for broadening the low-carbon energy mix in Malaysia, marking positive steps towards a more sustainable future.
