In a historic milestone for the global energy transition, wind power capacity has surpassed 50% of grid share in multiple countries worldwide during 2024-2025. This achievement marks a fundamental shift in how the world generates electricity.
The 50% Breakthrough
Denmark led the charge, with wind energy providing over 55% of its electricity in 2024. Ireland followed closely at 52%, while Portugal and Spain both crossed the 40% threshold. The United Kingdom generated 29% of its power from wind.
Global Wind Capacity Growth
Global wind power capacity reached 1,021 gigawatts (GW) by the end of 2024. China alone added 75 GW of new wind capacity in 2024, more than the rest of the world combined.
Technology Driving Costs Down
Modern offshore turbines now reach 15 MW capacity with rotor diameters exceeding 230 meters. The levelized cost of electricity from onshore wind has dropped to $30-40 per MWh in optimal locations.
Grid Integration Solutions
Managing a grid with 50% variable renewable energy requires significant infrastructure upgrades. Countries achieving high wind penetration have invested heavily in grid interconnections and battery storage.
Economic and Environmental Impact
The wind industry now employs over 1.4 million people globally. At current generation levels, global wind power prevents over 1.5 billion tonnes of CO2 emissions annually.
The Path to 2030
The IEA projects wind power must triple by 2030 to keep the world on track for net-zero by 2050. This requires installing approximately 390 GW of new capacity annually.
