In 2017, 53 GW of new wind power capacity was installed worldwide, bringing the global total to 539 GW – an 11% increase from the previous year. Offshore wind also saw tremendous growth during the year, thanks to a record 4.3 GW of new installed capacity. Wind power continues to be the second-largest source of renewable energy by installed capacity (following hydropower). However, there are still significant opportunities for technology innovation to maximize value and continue to improve cost-competitiveness.
Nearly 85% of the world’s wind generating capacity—and nearly all offshore capacity—resides in countries participating in the IEA Wind Technology Collaboration Programme (TCP). These countries added about 43 GW of capacity in 2017, accounting for over 80% of the worldwide market growth. The IEA Wind TCP is the leading international organization for wind energy research cooperation. For 40 years, the IEA Wind TCP has been multiplying national technology research, development and deployment (R,D&D) efforts through information exchange and joint research projects. Researchers from 24 member countries and international organizations have produced significant research results, design tools, and guidelines for the design and operation of offshore and land-based wind turbines through their national efforts and various research Tasks.
The IEA Wind TCP 2017 Annual Report highlights the work of 16 cooperative research Tasks, as well as the research and deployment activities of the 24 member countries and sponsor organizations. The overview chapter provides an extensive summary of how member countries benefit from wind energy, how much wind power generation each country has deployed, and how policies and research programs increase wind power’s contribution to the world energy supply.
