Overview
- The IEA’s 2026 Global Energy Review, released Monday, reports that solar supplied about 25% of 2025’s energy-supply growth, the most of any source.
- Global electricity use rose about 3% in 2025, while overall energy demand grew 1.3%, as buildings, factories, electric cars, and data centers pulled more power.
- Clean power from renewables and nuclear more than covered the rise in electricity demand, indicating fossil fuels lost share in power generation.
- Solar generation jumped by roughly 600 terawatt-hours in 2025, battery storage added about 110 gigawatts, and construction began on more than 12 gigawatts of new nuclear.
- Electric vehicle sales topped 20 million in 2025, helping limit oil demand growth to about 0.7%, while energy-related CO2 emissions rose roughly 0.4% with a decline in China.
