As of 2022, electricity consumption in Réunion shows a concerning reliance on fossil fuels, with fossil energy sources comprising about two-thirds of total electricity generation. Low-carbon or clean energy sources make up the remaining third, which indicates a significant room for improvement. The largest share of fossil energy comes from coal, accounting for nearly 28% of electricity, while the clean energy mix is dominated by hydropower, contributing roughly 19% to the electricity supply. Solar energy and biofuels also play a role, making up about 8% and 7% respectively, but each remains a relatively small slice of the energy pie. Given the global emphasis on reducing carbon footprints, it is imperative for Réunion to expand its low-carbon energy sources.

Is Electricity Growing in Réunion?
Examining the trends in electricity consumption, it appears that overall demand is on a declining trajectory in Réunion, with the 2022 figures showing a decrease from a consumption peak in 2020. Currently, electricity use stands at 3867 kWh per person, a drop of 533 kWh per person from the record high. However, there is a glimmer of hope in the realm of clean electricity; the latest data reveals a modest uptick in low-carbon electricity generation per person, which has reached an all-time high of 1320 kWh per person. This suggests potential for growth in clean energy, but highlights the pressing need for a broader and more ambitious transition to low-carbon electricity sources.
Suggestions
To bolster its low-carbon electricity generation, Réunion could draw inspiration from regions that excel in solar and nuclear power. Countries like France, where nuclear power accounts for 69% of electricity generation, showcase the potential for nuclear energy as a sustainable and dependable source. Solar energy, too, has shown promise in regions like Chile, where it contributes 24% to the electricity mix. Réunion could benefit from deploying more solar panels, benefitting from abundant sunlight similar to Lebanon's 31% solar share. By investing in solar and considering nuclear, Réunion can strategically reduce reliance on fossil fuels and build a greener, more sustainable electricity framework.
History
The history of low-carbon electricity in Réunion reveals periods of both growth and regression over recent decades. In the early 2000s, hydropower experienced minor fluctuations, with gains and losses mostly canceling each other out. The introduction of solar power in 2010 marked a significant step toward diversifying the clean energy portfolio. The last decade saw continued improvements, with hydro and solar expanding, although setbacks were not uncommon. A notable positive shift occurred in 2022 with a considerable surge in hydropower generation. This incremental progress suggests that Réunion has been treading cautiously in expanding its clean electricity capacity. A more aggressive pursuit of solar and nuclear energy could further capitalize on this trend, fostering substantial breakthroughs in sustainable electricity generation.
