As of 2022, Macao SAR China relies heavily on net imports for its electricity, accounting for more than 90% of its total consumption. Fossil energy sources like coal and oil play a negligible role, making up just over 5% of the electricity mix, while gas contributes around 4%. Low-carbon energy sources are also not heavily utilized, comprising approximately 3.5% of the electricity generated, with biofuels being the sole contributor. This emphasizes the need for a substantial shift towards clean energy to reduce reliance on imports and fossil fuels, both of which have significant negative impacts on the environment, including climate change and air pollution.
Macao SAR China can learn from successful countries to increase its low-carbon electricity generation. Countries like France, Slovakia, and Ukraine have effectively utilized nuclear power for more than half of their electricity, demonstrating the potential of this clean energy source. Denmark and Uruguay have achieved significant success with wind power, generating around 60% and 36% of their electricity from this sustainable resource, respectively. Solar energy, though less prominent in the dataset, provides a meaningful share in places like Greece and Australia. By investing in and adopting policies that promote nuclear, wind, and solar energy, Macao SAR China can enhance its energy security and reduce its environmental footprint.
The history of low-carbon electricity generation in Macao SAR China, specifically biofuels, shows a sporadic and minimal contribution since the early 2000s. In 2001 and 2003, there were minor increments of 0.1 TWh in biofuel-generated electricity, but throughout the subsequent years, there has been close to none, with occasional declines, such as the -0.1 TWh in 2015. For over a decade now, from 2007 to 2022, the biofuel contribution has remained stagnant at 0 TWh. This history indicates a lack of consistent development and integration of low-carbon electricity sources other than the currently negligible biofuels. It highlights the opportunity and necessity for Macao SAR China to diversify and expand its low-carbon energy portfolio with more robust and dependable sources like nuclear, wind, and solar power.
