As of 2023, electricity consumption in Congo - Brazzaville is heavily reliant on fossil fuels, contributing to more than three-quarters of the total electricity production. Specifically, natural gas alone accounts for nearly three-quarters of the electricity generated, marking a significant dependency on fossil sources. In contrast, low-carbon electricity generation accounts for about a fifth of the total, with hydropower being the primary clean energy source. This reliance on low-carbon options like hydropower is favorable compared to fossil energy, though still limited. More engagement with clean energy sources is essential to reduce the heavy dependence on fossil fuels, thereby reducing greenhouse gas emissions and combating climate change.
To enhance low-carbon electricity generation, Congo - Brazzaville can look towards a diverse set of clean energy sources similar to successful approaches adopted by other countries. Investing in nuclear power could significantly increase the clean energy share, learning from countries like France and Slovakia, where nuclear accounts for almost two-thirds of electricity consumption. Likewise, Denmark's success with wind energy, contributing to over half of its electricity, offers valuable insights into maximizing wind potential, especially in regions with favorable wind patterns. Solar energy can also play an essential role as demonstrated by Lebanon, where solar energy constitutes almost a third of electricity generation. By capitalizing on these clean technologies, Congo - Brazzaville can enhance its low-carbon electricity portfolio and reduce reliance on fossil fuels.
In the history of low-carbon electricity in Congo - Brazzaville, hydropower has seen various phases of growth and setbacks. Beginning in the early 1980s and into the 1990s, moderate and consistent increases in hydropower capacity were followed by some setbacks, noted especially in the early 1990s with minor declines. From 1996 onwards, growth was initially steady, followed by a period of stability and some improvement in the late 2000s and early 2010s. Notably, the years 2010 to 2015 showed consistent gains, emphasizing progressive development in hydropower capacity. In recent years, a slight decrease in 2019 highlights the importance of continued investment and modernization in this sector to sustain its contribution to the low-carbon energy mix, paving the way for more expansive clean energy integration.
