Electricity in Tonga in 2023
In 2023, Tonga's electricity consumption reveals a heavy reliance on fossil energy, with more than 85% of its electricity coming from fossil sources. Low-carbon energy sources account for a concise portion of Tonga's electricity generation, with solar energy making up the entire 14% share of low-carbon contributions. This highlights a significant opportunity for Tonga to expand its clean electricity portfolio and reduce its dependence on fossil fuels, which are known to contribute to climate change and air pollution.

Is Electricity Growing in Tonga?
The trends in Tonga's electricity consumption appear concerning, as indicated by a decline in per capita usage. In 2022, the record was 762 kWh per person, while the latest figures for 2023 dropped to 669 kWh per person, marking a decrease of 92 kWh. On a more optimistic note, Tonga's low-carbon electricity generation remains stable at 96 kWh per person, consistent with the record of 95 kWh from 2022. This stagnation in clean electricity generation, coupled with an overall decline in consumption, underscores the urgency to stimulate growth and expansion, especially in sustainable energy sectors.
Suggestions
To enhance its low-carbon electricity generation, Tonga could scale up its existing solar capabilities, which are already making notable contributions. In drawing lessons from other regions, Tonga can look towards countries like North Macedonia, which generate nearly half of their electricity from solar, and states like Nevada and California that leverage solar for over 30% of their electricity needs. While Tonga currently focuses on solar, expanding into nuclear energy could also be strategically beneficial, taking cues from France and Slovakia, where nuclear energy constitutes a significant majority of electricity generation. Together, these steps will ensure Tonga's energy future is more sustainable, reducing greenhouse gas emissions and safeguarding against the negative impacts of fossil fuel reliance.
History
Historically, Tonga's journey with low-carbon electricity, particularly solar energy, has been marked by consistent but stagnant activity throughout recent years, as no substantial changes in generation were reported from 2017 to 2023. This consistent lack of growth should be critically viewed as a missed potential, especially given the global urgency for low-carbon transitions and the inherent environmental benefits they promise. By recognizing this stagnant trend and making calculated investments in clean technologies, Tonga can pivot towards a more promising trajectory in its clean energy journey.
