Amsterdam, Thursday, 10 July 2025.
In June 2025, solar energy led the EU power mix for the first time, accounting for 22.1% of electricity generation, surpassing nuclear and wind energy, as report by think tank Ember.

Solar Energy Surpasses Conventional Power Sources

In June 2025, for the first time ever, solar power emerged as the largest source of electricity in the European Union, generating 22.1% of the total electricity output. This landmark achievement surpassed both nuclear, with a share of 21.8%, and wind, which contributed 15.8% of the energy mix. Overall, solar energy production reached 45.4 terawatt-hours (TWh) during the month, marking a significant milestone in the EU’s transition to renewable energy sources [1][2].

Key Drivers Behind the Shift

Several factors have contributed to solar power’s ascendancy. Record levels of sunshine and continued installations of solar technology across the continent have amplified this shift, alongside favorable policy environments facilitating the rapid growth of solar capacity. Notably, countries such as Germany, Spain, and the Netherlands, among others, reported their highest-ever monthly solar outputs [2][3]. This uptick in solar production underscores the EU’s strategic efforts to diminish its reliance on fossil fuels as part of a broader agenda to combat climate change [4].

The Netherlands’ Role in the Solar Surge

In Europe, the Netherlands plays a pivotal role in leading solar energy innovation, hosting organizations like Holland Solar, which advocates for the country’s solar sector growth and sustainability practices. Holland Solar has been instrumental in shaping policy and encouraging investments in solar technology, helping the Netherlands become a significant contributor to the EU’s renewable energy landscape. By influencing legislation and market conditions, the organization aims to cement the Netherlands’ position at the forefront of green innovation [5][6].

Challenges and Future Prospects

Despite the recent successes, challenges remain, particularly in areas such as energy storage and grid flexibility. Ember’s report highlights that to effectively harness the full potential of solar energy, Europe must invest in expanding battery storage capabilities to ensure a steady energy supply during non-sunlight hours. This development is crucial to reducing the dependency on fossil fuels and maximizing the efficiency of renewable energy resources [3][7].
