Solar generation rose by 636TWh in 2025, marking the largest increase of any power source on record. The International Renewable Energy Agency (IRENA) produces comprehensive, reliable datasets on renewable energy capacity and use worldwide. Renewable energy statistics 2025 provides datasets on power-generation. Ember (2026); Energy Institute - Statistical Review of World Energy (2025) – with major processing by Our World in Data This dataset contains yearly electricity generation, capacity, emissions, imports and demand data for European countries. You can find more about Ember's methodology in this. Solar PV accounted for 17.

Electricity generation by the U. In our latest Short-Term Energy Outlook (STEO), we expect U. 6% in 2027, when it reaches an annual total of 4,423 BkWh. Global solar photovoltaic capacity has grown from around 40 gigawatts in 2010 to approximately 2. Only in that last year. In 2025, global annual renewable capacity additions increased by 16%, reaching 800 GW despite challenges linked to supply chain strains, grid connection delays, financial pressures and policy shifts.
