Solar and wind supply 13% of Mexico's electricity generation, per BloombergNEF

Solar and wind generation supplied around 13% of Mexico's electricity in 2025, according to the data BloombergNEF presented at the 16th Joint Congress of Energy Associations, reported on October 7, 2026 by La Jornada.

The same diagnosis places natural gas at the center of Mexico's electricity system: 63% of generation comes from that fuel and almost three quarters of the total comes from fossil sources, according to La Jornada's coverage. Petróleo y Energía detailed that Chile reached about 39% solar and wind generation in 2025, Brazil 29%, Argentina 17%, Peru 10% and Colombia 5%, a comparison that places Mexico at the low end of the region despite having followed a trajectory close to those markets at the start of the period analyzed. The reading comes from the presentation Mexico's Energy Outlook to 2030, by Stephan Mothe, associate researcher at BloombergNEF (BNEF), an analysis firm of the Bloomberg group.

Dependence on imported gas completes the picture. Around 70% of the gas used to generate electricity in 2025 came from imports, most of them from the United States, and BNEF projects that proportion will reach 84% in 2030 under the trends presented at the congress, according to La Jornada. The firm's Mexico Transition Factbook 2026 estimates that net gas imports from the United States will cover 80% of the country's total gas supply in 2030, up from 75% in 2025, and puts investment in new generation capacity through 2035 at 63 billion dollars, with nearly 30 GW of additional solar, wind and storage by 2030. Mothe framed that dependence as a matter of national sovereignty as well as sustainability, in the context of the USMCA renegotiations, according to La Jornada.

Mothe noted that the regulatory changes underway open space for distributed generation and self-consumption, segments that can add capacity amid growth in industrial demand. The data point to watch is whether investment in generation and grids accompanies that framework: BNEF projects 269 GW of installed solar, wind and storage in Mexico by 2050.
