Abstract

Wind energy should contribute significantly to the energy transition toward a decarbonized society in the next few decades. Although plans are being devised to deploy large offshore wind farms, onshore wind turbines are still very competitive in term of installation and operational costs. The density of onshore wind farms will therefore certainly increase in some areas. Noise regulations can result in high curtailment rates and energy yield losses. Noise plays also an important role for social acceptance of wind energy.

The lecture will start with general aspects of wind energy, such as technology, future trends and challenges, in particular related to noise. The focus will move toward the specificities of wind turbine generated noise. Mitigation techniques currently used in the industry will be addressed. Finally, latest developments and cutting-edge technology for noise reduction will be described, with a future outlook on possible advancements in this domain.
