Health Canada's wind turbine health study
is doomed to irrelevance, because is largely based on asking
people whether they are annoyed about wind turbines. With this
methodology, Health Canada could "prove" that
people are annoyed and distressed about any number of things:
extreme summer heat and drought; traffic congestion; electricity
rates; taxes; gun crime, etc. And I expect they could prove
annoyance and sleep disturbance among people near a wide range of
noise sources, including highways, airports, gun clubs, racetracks,
Toronto's entertainment district, motorcycles, outdoor bars and the Indy.
Among other things, Health Canada's plan lacks one critical
feature of a good study: it will not isolate the alleged
noise impact from the subjects' preconceived opinions about
turbines. Compare the much better study of 725 Dutch
residents done by the University of Groningen, where wind turbines
are widespread: WINDFARM perception.
