Researchers Osea Giuntella (University of Pittsburgh), Doug Almond (Columbia University) and Niklas Rott (University of Augsburg) studied whether wind turbines cause detectable health harms. Their analysis appears in the journal Proceedings of the National Academy of Sciences. To build stronger evidence than earlier aggregate studies, they used geographic information system data to locate turbines, consumer purchasing records and a longitudinal data set that followed households near turbines over time.
The data follow more than 120,000 households near turbines installed between 2011 and 2023 and cover a typical exposure distance. The team compared health measures in the years before a turbine was installed to the years after, examining headaches, depression and anxiety, sleep problems, and purchases of painkillers and sleep aids.
The analysis found no moderate-to-large adverse health impacts from exposure to wind turbines and said the results rule out meaningful harms at typical exposure levels. The authors noted one limitation: very small effects below their minimum detectable threshold cannot be ruled out. They also considered infrasound but found no clear health link, and they noted other disamenities can reduce quality of life.
