Solar energy generated more electricity than any other source in Portugal during July, marking a historic milestone for the Iberian power system.

Data released by grid operator Redes Energéticas Nacionais (REN) shows solar accounted for 19% of total consumption, surpassing wind, which contributed 13%.

In total, renewable sources covered 53% of Portugal's electricity demand last month.

The shift underscores the accelerating penetration of intermittent renewables in the national mix.
