And in fact, no windmills at all – they’re killers! From Overlawyered.com:
Some opponents of wind turbine farms in Maine say they’re concerned not just about audible noise but “low-frequency noise, so soft you can’t hear it,” from the installations, which they claim is linked to a wide array of health problems, not to mention “the strobe effect created by the sun setting behind the spinning blades, which some say can lead to seizures”. On an anti-turbine website, a New York doctor describes “acoustic radiation” as a mix of “audible sound, infrasound and vibration, in a pulsating character, that appear to trigger serious reported health problems in those families living near wind turbine installations.” State officials in Maine, on the other hand, would prefer to keep the focus on sound levels loud enough to actually be noticed:
The state’s chief medical officer has her doubts about turbine-related health effects. When it comes to potential hazards, “If anything, there’s evidence to put a moratorium on fossil fuels not on wind turbines,” Dr. Dora Ann Mills said Friday.
