Once again no one is surprised to discover that you blatantly lied yet again!
Let's just put your lie back up here so that everyone can reference it;
Now let's look at what the links you provided actually stated;
From the first link;
(Washington, DC, December 10, 2013) A new study shows that in spite of updated designs, U.S. wind turbines are killing hundreds of thousands of birds annually—a number that may balloon to about 1.4 million per year by 2030,
The study does not say anything at all about bats and merely claims "hundreds of thousands of birds" without specifying exactly how many. The estimate for 2030 was made in 2010 so it was projecting out 20 years. Unfortunately no basis was provided for that projection.
The second link from USGS mentions bats but gives no statistics at all.
The 3rd link from Popular Science states "
600,000 to 900,000 bats every year, according to a new study" but that is well below Westwall's claim. Note that the following article is about a bat species threatened by an oil pipeline. Don't see WW whining about those bats.
The Science Daily link states
"bat deaths caused by wind turbines concludes that more than 600,000 of the mammals likely died this way in 2012 in the contiguous United States." Again this is well below Westwall's bogus claim.
The last link states
"A new study published in the journal BioScience estimates that more than 600,000 bats died from interactions with wind turbines".
So from everything provided it is clear that Westwall was lying when he claimed that
"windmills kill" "1.5 million bats per year at minimum".
But it gets even worse for Westwall since NONE of his links substantiated his claim that
"windmills kill 600,000 birds".
Needless to say I don't expect anyone with Westwall's lack of honesty and integrity to admit that he lied.
He will probably want to delete this post so I will just remind him that I make copies of everything and since this post is directly on the OP topic of "death by wind turbine" he will have a hard time explaining it away if he does delete it because it exposes his lies.
