52.4% of our country’s electricity production in August was renewable, and 74.1% did not emit CO2 equivalent. Solar photovoltaic has covered a quarter of demand and is once again the top technology in the mix for the fourth consecutive month, with production 8.5% higher than in August 2024.

The financial markets reflect the boom in renewables in Spain: in 2025 more than 56% of electricity generation comes from these sources, with Solaria rising by 10% and drivers such as Acciona Energía and Iberdrola diversifying and modernising.
