Forecast vs actual

How each edition’s forecast compared with what happened.

IMF: GDP growth IEA: solar and wind US EIA: energy

Each line is one WEO edition's main scenario. The black line is what happened (Ember). Ember's solar includes concentrated solar power; IEA's row is solar PV only. IEA and Ember also count capacity differently (2024: 2,164 GW vs 1,880 GW).
