European photovoltaics have been instrumental in generating enough electricity since early March to avoid €10 billion in gas imports, with daily savings averaging €110 million. This increase in solar power generation is due to expanded photovoltaic capacity, reaching 65 GW in 2025. Renewable energy sources collectively met 46.4% of Europe's electricity demand in 2025, with wind and solar surpassing coal- and gas-fired power plants for the first time. The energy crisis triggered by Russia's invasion of Ukraine has cost the EU €1.7 trillion to date, highlighting the importance of investing in and expanding renewable energy sources to reduce reliance on fossil fuels.
