Electricity in Tonga in 2023

As of 2023, electricity consumption in Tonga is predominantly reliant on fossil fuels, which constitute around 86% of the overall electricity mix. Low-carbon sources, including solar energy, account for the remaining 14% of the electricity produced. Within the low-carbon category, solar energy is the exclusive contributor, providing the full share of 14%. This reliance on fossil fuels indicates a significant opportunity for growth in sustainable energy development in Tonga, given the current dependency on non-renewable sources with environmental implications such as climate change and air pollution.

Suggestions

To enhance low-carbon electricity generation, Tonga can focus on expanding its existing solar capacity, as solar energy is already contributing effectively to its current green power mix. By looking at countries like Uruguay and Cape Verde, Tonga can draw inspiration; these nations have harnessed low-carbon resources, with Uruguay generating 28% of its electricity from wind. While solar is Tonga's current low-carbon resource, learning from the success of wind in similar resource-rich regions could provide valuable insights for diversifying the low-carbon portfolio. Moreover, observing how countries like Lebanon have integrated solar energy to reach up to 31% of their electricity generation suggests effective pathways for solar expansion in Tonga.

History

The history of low-carbon electricity in Tonga, especially solar, indicates a period of stability with no additional contributions over several years. From 2017 through 2023, Tonga saw no incremental increase in solar energy generation, maintaining a constant input from this source. This static growth highlights an untapped potential and the need for strategic investment in solar and other clean technologies to build up its sustainable electricity share further. The consistent level year after year underscores the importance of future interventions to boost Tonga's low-carbon electricity generation and reduce reliance on fossil fuels.
