In 2022, the majority of Réunion's electricity consumption was still reliant on fossil fuels, with more than half, approximately 66%, coming from these non-clean sources. The largest contributor within the fossil category was coal, making up over a quarter of total electricity consumption. Low-carbon electricity, however, formed just over a third of the total electricity mix, with the most significant contributors being hydropower and solar, at nearly 19% and 8%, respectively. Biofuels accounted for a smaller percentage, around 7%. This data highlights a substantial reliance on fossil energy, underscoring the pressing need for further development of green energy alternatives such as nuclear and solar to reduce carbon emissions and mitigate climate change impacts.

Is Electricity Growing in Réunion?
Recent electricity consumption trends in Réunion demonstrate a concerning decline. In 2022, the island's per capita electricity consumption was 3867 kWh, a notable decrease of over 500 kWh per person from its previous peak in 2020. While overall consumption has decreased, there's a silver lining in the growth of low-carbon electricity. In 2022, low-carbon electricity generation reached 1320 kWh per person, exceeding the previous high recorded in 2013, marking a modest increase. This uptick in green energy highlights local efforts to shift towards cleaner electricity, though the overall drop in consumption raises questions about future energy needs and achieving sustainable growth.
Suggestions
To augment low-carbon electricity generation, Réunion can draw inspiration from regions with high shares of solar and nuclear energy. For nuclear energy, France and Slovakia showcase exemplary cases with close to two-thirds of their electricity derived from nuclear sources. As for solar energy, regions like North Macedonia, where nearly half of the electricity comes from solar, could serve as a model for Réunion's solar initiatives. By investing in nuclear and solar infrastructure development, Réunion could significantly reduce its reliance on fossil fuels and move towards a greener, more sustainable electricity future. Embracing these strategies will not only support local electricity demand but also contribute significantly to reducing global carbon footprints.
History
Tracing back the journey of low-carbon electricity in Réunion, the turn of the century was characterized by fluctuations in hydropower, with minimal growth until a notable increase in solar energy around 2010. Between 2001 and 2020, hydropower experienced several ups and downs but without significant upward trends. An appreciable rise in hydropower came in 2022 with an increase of 0.3 TWh, marking the most significant leap for hydropower in over a decade. Furthermore, solar began gaining traction in 2010, counterbalancing some of the declines witnessed in hydropower. Although the progress has been somewhat erratic, recent changes indicate an opportunity for focusing on stabilizing and expanding low-carbon electricity, particularly through solar and potentially nuclear options, for a more robust and sustainable electricity sector in Réunion.
