In June 2025, solar power became the leading source of electricity in the European Union for the first time, surpassing wind, nuclear, and coal energy. This milestone was driven by exceptional sunlight and increased solar capacity across the region. Nearly a quarter of Europe's electricity in June was generated from solar energy, marking a historic shift in the EU's energy landscape. The contribution of coal reached an all-time low during this period. Countries such as Belgium and France also recorded solar power as their primary electricity source in June. On particularly sunny days, Europe generates more solar energy than it can immediately consume or store, highlighting both the growth and challenges of solar integration. This development reflects a significant transformation in Europe's renewable energy sector, according to data from the energy think tank Ember and various European news sources.
