Half‑capacity, Not Half‑generation

Global renewables now make up roughly 49.4% of installed electricity capacity, but that does not mean they produce half of electricity (variable sources like solar and wind were ~35% of capacity). The IRENA 2026 statistics also show a rebound in non‑renewable capacity additions (renewables' share of 2025 additions fell to 85.6% from ~92% in 2024), signaling that the transition’s pace and system impacts are more complex than headline capacity shares suggest. — Distinguishing installed capacity from actual generation and noting the recent rebound in fossil/other non‑renewable additions changes how policymakers and markets should assess energy security, grid investment needs, and emissions trajectories.
