Portugal achieved 100% renewable energy supply for six consecutive days.

Redes Energéticas Nacionais, the largest energy company in Portugal, reported that wind and waves generated the entire nation's energy supply.

The conditions persisted for five additional days, with some periods of exporting renewable electricity to Spain.

The total duration of renewable energy generation was 149 hours, with 95 hours of exporting to Spain, breaking the previous record for consecutive days of 100% renewable use.

The record was achieved during rainy and windy weather, emphasizing the role of wind power in Portugal's renewable energy mix.

Many wind turbines were built in the 1990s when solar panels were not cost-effective, contributing to the reliance on wind energy.

Portugal's history includes the construction of hydroelectric dams after the fall of the dictatorship in 1974.

The country faces challenges due to the inverse correlation between sunny and windy days, leading to a focus on wind power during less sunny periods.

The next development in Portugal's renewable energy sector is expected to be the establishment of deepwater offshore wind farms.

 Future plans include developing deepwater offshore wind farms for sustained renewable energy.
