Electricity in Tonga in 2023
In the year 2023, the electricity consumption in Tonga heavily relies on fossil fuels, with more than 85% of electricity generated from these energy sources. However, Tonga is making strides towards cleaner electricity with low-carbon energy contributing nearly 15% to its electricity mix, exclusively from solar power. Despite being a modest share, solar energy plays a crucial role, demonstrating the country's commitment to adopting greener technologies. The transition towards low-carbon energy is a positive step, yet there is enormous potential for further growth beyond the small slice of clean energy that currently powers the nation.

Is Electricity Growing in Tonga?
The electricity consumption in Tonga seems to have experienced a decline. The latest figures for 2023 indicate a decrease from last year's record of 762 kWh per person to 669 kWh per person. This indicates a reduction by 92 units per person, showing that electricity use is not on an upward trend. However, on a brighter note, low-carbon electricity generation has maintained its output, with a marginal increase in per capita generation from 95 kWh to 96 kWh. Although this growth is not substantial, maintaining steady production of clean electricity is an essential foundation on which to build future advancements.
Suggestions
To increase low-carbon electricity generation, Tonga should focus on expanding its existing solar infrastructure. Solar energy, which already contributes significantly to the country's clean energy production, can be extended to capture more of the abundant sunshine. Learning from successful regions like Nevada, where solar power constitutes a considerable share of energy, can be invaluable. Moreover, Tonga might also consider evaluating the experiences of countries with substantial wind or nuclear energy integration. Though wind appears less prioritized presently, regions such as Iowa and Denmark with their successful wind energy models, provide a blueprint for diversifying Tonga’s clean energy portfolio. Additionally, exploring possibilities for nuclear energy, as adopted by countries like France, could be instrumental for long-term sustainability.
History
The history of low-carbon electricity in Tonga, specifically solar energy, has seen a plateau over recent years. From 2017 to 2023, solar electricity generation recorded no significant year-to-year changes. This stagnation reveals missed opportunities in leveraging the full potential of solar technologies. The stagnant period should serve as a call for renewed efforts to amplify Tonga's solar capacity, turning the static record into a story of dynamic growth and progress in sustainable energy. These efforts are crucial for reducing dependency on fossil fuels, which contribute to climate change and air pollution, and advancing Tonga’s role in integrating affordable and clean electricity solutions.
