Condensed from Mike Barnard's report:
Interestingly, Canada is by far the most litigious, and Ontario had almost 30% of the cases by itself. Belief in health impacts varies substantially by geography; where anti-wind groups are strongly pushing the idea, people get afraid and try to prevent wind farms based on their health fears. They fail.
This is just in regards to cases involving alleged harm to health. Harm to property values has been another area of complaint. So far cases that have pressed that concern have also, generally speaking, failed.
