Electricity in Réunion in 2021

In 2021, Réunion primarily relied on fossil fuels for its electricity consumption, with more than 70% of the electricity being generated from these sources. Coal alone accounted for about 30% of the energy mix, underscoring the heavy dependence on fossil energy. On the other hand, low-carbon energy sources contributed approximately 28% of the island's electricity production. Among these, hydropower and solar energy contributed nearly 12% and 9%, respectively, while biofuels added close to 8%. Despite the presence of these low-carbon sources, the reliance on fossil fuels is substantial, pointing towards potential climate and environmental challenges that accompany such dependence.

Suggestions

Réunion has significant opportunities to increase its low-carbon electricity generation by looking at global examples. Although nuclear energy is not currently part of Réunion's energy mix, its successful adoption in countries like France and Slovakia, where it accounts for more than half of the electricity generated, presents a compelling case for consideration. Alternatively, increasing investment in solar energy could mirror successes seen in Greece and Chile, where solar energy contributes around 22% of electricity production. Furthermore, Réunion could look to Cape Verde as a regional example, where wind energy makes up 14% of electricity sources, demonstrating the viability of diversifying into wind power. Emphasizing the expansion of nuclear, wind, and solar energy would substantially diminish dependency on fossil fuels and reduce greenhouse gas emissions.

History

The history of low-carbon electricity generation in Réunion reveals fluctuations, particularly in hydropower and biofuel contributions. During the 2000s, hydropower showed both increment and decrement changes, bouncing from reductions in some years like 2001 and 2004, to increases such as 2006 and 2007. The introduction of solar energy in 2010 marked a transition towards diversified low-carbon sources, with initial increments seen in subsequent years like 2011. The 2010s witnessed continued variable outputs in hydropower and biofuels but highlighted potential growth through increased solar generation. Despite some setbacks, the gradual rise of solar energy points toward a growing commitment to sustainable low-carbon sources, laying the groundwork for future expansions.
