I find it ironic that the anti-frackers, who use some unproven safety argument to dismiss fracking are equally pro-wind power. They obviously are unaware of the safety issues regarding wind power. 144 people have been killed as a result of wind power, the majority of which were in the last 10 years. There have also been multiple accidents causing injury and damage. I suggest you look at the link below.

In comparison, the worst nuclear accident in the last 10 years, Fukushima, caused no direct deaths. The long term deaths due to cancer are predicted to be extremely low to none according to the World Health Organisation.
So as well as being useless (as stated earlier), wind power is also dangerous.
