As of 2023, El Salvador's electricity consumption predominantly comes from clean energy sources. Low-carbon sources contribute more than two-thirds of the total electricity, with hydropower and geothermal making up substantial portions at about 20% each. Solar energy is also a significant contributor, generating more than one-eighth of the electricity. Meanwhile, fossil fuels account for less than a third of the electricity supply, predominantly utilizing gas for over 18% of energy needs. Biofuels, although less significant at approximately 11%, also contribute to the country's low-carbon footprint. Net imports, which are close to none, round out the energy mix.
El Salvador has significant potential to increase its low-carbon electricity generation by expanding existing solar capacity. The successful experiences of other countries in integrating wind and nuclear energy into their electricity supply can serve as valuable lessons. For example, Uruguay's success in generating over a third of its electricity from wind power demonstrates the viability of such an approach in a nation with geographical and economic similarities. Additionally, several countries achieve substantial shares of low-carbon electricity through nuclear, such as Slovakia and France, which could inspire El Salvador to consider similar strategies for future growth.
Historically, low-carbon electricity generation in El Salvador has experienced fluctuations in contributions from various sources, especially hydropower. In the late 1970s and early 1980s, hydropower showed some growth, despite a notable decline in 1982. Throughout the 1990s and into the early 2000s, a pattern of modest gains and drops continued. More recently, the 2010s saw some stabilization and even increases, with 2020 marking a notable period of growth in both hydropower and solar, reflecting El Salvador's commitment to expanding its clean electricity infrastructure. Although recent years have seen some decreases in hydropower generation, the expansion of solar energy provides a promising pathway towards enhanced low-carbon electricity generation in the future.
