Réunion's electricity consumption in 2022 reflects a significant reliance on fossil fuels, with more than half of the electricity coming from these sources. Specifically, fossil energy, including coal, constitutes about 66% of the electricity mix, whereas clean or low-carbon energy sources make up roughly 34%. Among the low-carbon sources, hydropower is the most significant, accounting for about 19% of the total electricity generation. Solar energy follows with an 8% share, while biofuels contribute approximately 7%. The current electricity mix indicates a clear need to pivot more aggressively towards low-carbon energy sources, especially considering the global movement to reduce emissions and foster sustainability.

Is Electricity Growing in Réunion?
Examining the trend of electricity consumption in Réunion reveals a decrease in overall electricity use per person from its peak in 2020. The latest figure for 2022 shows consumption at about 3867 kWh per person, which is a decline of 533 kWh from the previous record in 2020 at 4400 kWh per person. On a positive note, the generation of low-carbon electricity has grown, setting a new record of 1320 kWh per person in 2022, surpassing the previous record set in 2013. Despite this progress in low-carbon generation, the overall decline in electricity consumption is concerning as it could indicate stagnation, hindering the growth needed for economic development and future demands such as electrification and advanced technological applications.
Suggestions
To increase low-carbon electricity generation, Réunion could benefit from focusing on solar and nuclear power, taking inspiration from regions with successful low-carbon electricity implementations. For instance, Nevada has achieved a solar energy contribution of 34%, and Lebanon has 31% from solar as well, showcasing the potential of utilizing abundant sunlight. Moreover, countries like France and Slovakia have successfully embraced nuclear power with contributions of 67% and 66%, respectively. By learning from these examples, Réunion can potentially enhance its clean electricity capacity, contributing to reduced reliance on fossil fuels and advancing towards a sustainable future.
History
Over the years, Réunion has experienced fluctuations in low-carbon electricity generation. In the early 2000s, hydropower faced some inconsistencies with minor declines and gains, but by the mid-2010s to late 2010s, there was more stability and growth, particularly with a notable 0.3 TWh increase in 2022. Solar energy began to contribute significantly from 2010 onwards, showing consistent growth. Meanwhile, biofuels, despite being counted as low-carbon, have displayed some ups and downs. Overall, the historical trend illustrates the importance of investing robustly in stable and scalable green energy solutions like solar and nuclear to secure future energy needs effectively and sustainably.
