In August 2025, electricity generation in Latin America and the Caribbean reached 161 TWh, a level similar to that of the previous month. Nevertheless, variations were observed in the relative shares of the different generation sources, along with a positive year-on-year increase of 3.9% compared to August 2024, confirming a trend of moderate but sustained growth in the regional electricity sector.
Hydropower remained the main generation source, with a share of 43.6%, although it recorded a month-on-month decline associated with less favorable hydrological conditions in several subregions. This reduction was offset by a higher contribution from natural gas, which reached 26.1% of the total, consolidating its role as a key component for the reliability and stability of electricity supply.
Non-conventional renewable energy sources, particularly wind and solar, continued to expand thanks to new installations and the availability of natural resources, contributing to the diversification of the regional electricity mix. However, the increased use of thermal sources led to a decline in the renewability index, which stood at 63%, one of the lowest values observed over the past five months.
Despite this trend, the data reveal marked heterogeneity among countries: while Paraguay, Costa Rica, and Uruguay display electricity mixes that are virtually 100% renewable, other countries remain highly dependent on fossil fuels, reflecting the differing paces and challenges of the energy transition across the region.
