In 2023, Tonga's electricity consumption is heavily reliant on fossil fuels, with more than four-fifths of its electricity being generated from these sources. In contrast, low-carbon energy, which in Tonga's case is entirely solar, accounts for just over one-seventh of electricity generation. This means solar energy represents the entirety of the nation's clean electricity, highlighting a significant dependency on fossil fuels and a rather limited contribution from low-carbon sources. For a sustainable future and to reduce the negative impacts of fossil fuels, it is crucial for Tonga to diversify and increase its clean energy portfolio.

Is Electricity Growing in Tonga?

The trajectory of electricity consumption in Tonga is concerning, with a noticeable reduction in total electricity consumption per person from a previous high of 762 kWh in 2022 to 669 kWh in 2023. This decrease signifies a change of -92 kWh/person, underscoring a decline rather than growth in electricity use. On a more positive note, low-carbon electricity, which saw a minute increase of 1 kWh/person, has remained stable yet unimpressively low. This stagnation highlights the need for action in bolstering the growth of clean electricity to meet both current and future demands.

Suggestions

Tonga has room to boost its low-carbon electricity generation, with solar energy expansion being a clear path due to its already established presence. Beyond expanding solar, Tonga could look at regions successful in utilizing wind and nuclear energy to diversify its clean energy mix. Denmark's remarkable achievement of generating 60% of its electricity from wind and New Mexico's success with 36% wind share demonstrate the viability and benefits of developing wind infrastructure in regions with suitable conditions. Nuclear energy also presents a significant potential, with countries like France and Slovakia showcasing the profound impact this low-carbon source can have, generating about two-thirds of their electricity from nuclear. By drawing from these examples, Tonga can develop a robust strategy for increasing its clean electricity generation.

History

Looking at Tonga's history of low-carbon electricity, it is clear that there has been an unfortunate stagnation over recent years. Since 2017, Tonga's solar electricity generation has seen no growth, which indicates a missed opportunity for capitalizing on solar energy potential. Such years of little to no progress contrast with global trends that embrace low-carbon sources to curb climate change impacts. Tonga's path forward should be one of catching up with the rapid changes elsewhere, placing a strong emphasis on accelerating the adoption and expansion of its solar capabilities, while also exploring the introduction of wind and potentially nuclear energy where feasible. This approach will help Tonga to not only enhance its energy security but also align with broader goals of sustainability and growth in clean electricity.
