In 2022, Réunion's electricity consumption heavily relied on fossil fuels, accounting for approximately two-thirds of the total energy mix. Coal was the dominant fossil source, making up more than a quarter of the overall consumption. Conversely, low-carbon energy sources, which include hydropower, solar, and biofuels, contributed to roughly a third of the electricity mix. Hydropower was the leading clean energy source, providing nearly a fifth of the electricity, followed by solar at about 8% and biofuels at about 7%. This highlights the need for substantial improvement in clean energy generation to reduce reliance on fossil fuels, which are significant contributors to climate change and air pollution.

Is Electricity Growing in Réunion?
Electricity consumption in Réunion is showing signs of stagnation, raising concerns about the region's ability to keep pace with increasing demand. The total electricity consumption in 2022 stood at around 3867 kWh per person, which is noticeably lower than the 4400 kWh per person recorded two years earlier in 2020. While there is a slight uptick in low-carbon electricity generation, from 1262 kWh per person in 2013 to 1320 kWh in 2022, the overall decline in electricity consumption is worrying. This situation calls for renewed efforts to foster sustainable electricity growth, which is crucial for the transition towards a greener economy.
Suggestions
Réunion can take several cues from other regions to boost its low-carbon electricity generation. France and Slovakia are exemplary for their significant reliance on nuclear power, contributing 70% and 66% of their electricity from clean nuclear energy, respectively. Réunion could similarly explore the expansion of nuclear energy as a viable and substantial low-carbon option. In the realm of solar energy, states like Nevada, with 33% of electricity from solar, and California, achieving 29%, demonstrate the potential of solar power. With its abundant sunshine, Réunion could optimize solar deployment significantly. By tapping into nuclear and solar energy solutions, Réunion can make strides toward a more sustainable energy future, reducing its dependence on fossil fuels.
History
Looking at the history of low-carbon electricity in Réunion, the early 2000s saw fluctuations in hydropower contributions, with years of both decline and growth. In the year 2010 and the following years, solar energy began to make its mark with steady increments. More recently, in the late 2010s and into 2022, biofuels and hydropower have shown mixed results, yet hydropower notably surged by 0.3 TWh in 2022. This varied history underscores the importance of strengthening sustainable energy policies, with an emphasis on expanding cleaner sources like solar and potentially nuclear. Such measures will ensure a more resilient and sustainable electricity supply for the future.
