IEA Wind TCP Annual Reports


thumbnail image



The IEA Wind TCP has been researching and developing wind related technologies since 1977. The early pioneers of wind worked in relative obscurity envisioning a bright future for wind energy. Over several decades, larger and more efficient turbines now generate huge amounts of renewable energy.

Our Annual Reports highlight the work of the current research Tasks and provide an extensive summary of the how member countries benefit from wind energy, how much wind power generation each country has deployed, and how policies and research programs will increase wind power’s contribution to the world energy supply.
