Electricity in Singapore in 2025
As of 2025, Singapore's electricity generation heavily depends on fossil fuels, with more than 95% coming from this source. The vast majority of this is attributed to gas, making up approximately 94%. In stark contrast, low-carbon electricity, which is crucial for reducing greenhouse gas emissions and combating climate change, only accounts for a small sliver of Singapore's electricity generation, representing just under 3%. This low-carbon portion is exclusively generated from solar energy. The reliance on fossil fuels for electricity in Singapore underscores the urgent need for significant transition towards more sustainable energy sources for future sustainability and energy security.

Is Electricity Growing in Singapore?
In terms of electricity consumption, Singapore is experiencing a modest growth. The average consumption per person in 2025 stands at approximately 10,483 kWh, showing a slight increase from the previous year's record of 10,400 kWh per person. However, the alarming decline in low-carbon electricity consumption is concerning. The latest numbers indicate a person-based electricity generation of 285 kWh in low-carbon electricity, which has decreased significantly by 226 kWh compared to the record set in 2024. This decline in clean energy usage, amid a general climb in overall consumption, presents a critical area for intervention to ensure sustainable energy growth.
Suggestions
To bolster its low-carbon electricity generation, Singapore can draw inspiration from other regions that have successfully embraced green energy technologies. While it may lack the extensive land needed for large-scale wind farms, Singapore can prioritize solar energy, taking cues from states like Nevada and California, which generate around a third of their electricity from solar. Furthermore, Singapore could consider exploring nuclear options, given the significant proportion of electricity it provides in countries like France and Slovakia, each with more than 65% of their electricity from nuclear energy. By investing in both solar and nuclear, Singapore has the potential to greatly enhance its clean energy portfolio.
History
Historically, Singapore's transition to low-carbon electricity has seen slow yet steady increments. Biofuels made minor contributions to its energy mix as early as the mid-1980s, but it wasn't until the mid-2010s that a consistent contribution was observed. Between 2016 and 2025, solar energy gradually expanded with moderate annual increases. Of particular note is the period between 2019 and 2025, during which solar generation increased consistently each year. While the recent history indicates a positive trajectory for solar energy, the absence of similar growth in other clean technologies like nuclear presents an opportunity for future developments to diversify the energy mix further and achieve significant progress towards low-carbon electricity in Singapore.
