Twelve countries in the European Union (EU) failed to install „a single wind turbine” last year, the CEO of industry body WindEurope said Thursday. Giles Dickson said that while more and more people and businesses were benefiting from wind power, many things were „not right” beneath the surface.

Dickson added that growth in onshore wind fell by more than half in Germany last year and „collapsed in the U.K.”, stating that, in the EU, 2018 was „the worst year for new wind energy installations since 2011.” The latter figure reflected regulatory changes undertaken by EU member states following a review of state-aid guidelines, according to CNBC.

In Germany’s onshore sector, the group explained that „lengthy permitting processes” and projects with „longer build-out periods” had resulted in a „significant decrease” in installations, which fell from 5,334 megawatts in 2017 to 2,402 megawatts (MW) in 2018.

While investments for future capacity were deemed to be „quite good” in 2018 thanks to the U.K., Spain and Sweden as well as expansion in offshore wind, Dickson said that the outlook for new investments remained uncertain.

„There are structural problems in permitting, especially in Germany and France,” he added. „And with the noble exception of Lithuania and despite improvements in Poland, there’s a lack of ambition in Central and Eastern Europe.”

Overall, Europe installed 11.7 gigawatts (GW) of gross wind power capacity in 2018. While this represents a drop of more than 30 percent compared to installations in 2017, the sector still installed more capacity than any other type of power generation in the EU last year, WindEurope said.
