Study finds no major health harms from wind turbines ^{CEFR A2}

Researchers from three universities investigated whether wind turbines harm people's health. They used maps of turbine locations, consumer purchase records and a long data set that followed households near turbines over many years. The team compared the same households before and after turbines were installed nearby.

The researchers looked at headaches, depression and anxiety, sleep problems, and purchases of painkillers and sleep aids. They found no moderate-to-large health effects at typical distances. However, they said very small effects that are hard to detect cannot be completely ruled out. They also noted noise, shadow flicker and visual intrusion can upset local residents.
