Accoridng to a BBC news article, there is another problem with wind turbines. According to a Taiwanese farmer many of his goats have died due to lack of sleep because of excessive turbine noise.
My fear is that this will prove to be another issue which is used against UK wind farms in planning. At present wind farms in the UK have problems with planning due to noise and this may make thing worse, especially as the land around wind farms is often used for grazing. Whilst it is unlikely that the risk of livestock deaths will solely be used as grounds for rejecting a wind farm there is the chance that it will further encourage protestors. However, there are a few things which may mitigate this risk. As far as I am aware, this is not a recognised problem so far in the UK. In addition, many farmers earn quite handsomly from wind turbines on their land, and so this extra income will more than make up for the potential loss of grazing land. As such, I believe the majority of farmers will not bother too much about this latest 'problem', with the only farmers who vociferously object being those who don't get any financial incentive from having windfarms (for example tenant farmers and those who's land borders win farms).
