Approval process by government is now much stricter and the approval process takes longer for new wind turbines. A leading renewable energy developer BayWa re. estimates 45% of the old turbines installed 20 years ago would not be approved under today's stricter standards. As these become unprofitable a lot of new turbines have to replace older ones. After years of gains suddenly in 3 years the wind power capacity installed each year is dropping sharply, and is in deep trouble. Especially because wind energy plays a big role in Germany, accounting for 25% of total electricity production in 2019, solar only has 10%.

For all of Germany only 290 MW was installed in first half of 2019, 80% drop from same period 2018.  In 2018 2800 MW of wind turbines were installed, and that was down from 5000MW in 2017.

Problems in addition to stricter approval standards is the resistance from the public which fears wind turbines close to residential areas could affect health of residents. In Bavaria 10H ban is imposed on new installations, requiring 10 times the height of the wind turbine as minimum distance from homes. Other issues are wildlife and the impact on  birds in the area. 300 turbines for 1200 MW are blocked for this reason. Other reasons are military concerns, FM radio beacons. It used to take 10 months for approval. Now the process is so long that the technology itself has changed by that time. Commercial risks are growing for operators in this environment as new costly regulations come into place. A regulation in Brandenburg requires payment of 10,000 euros to neighboring municipalities per wind turbine. Subsidy eligibility is also being cut.
