They left out bats. Giant commercial wind generators are murder on bats because the vibrations seem to attract them. And they might have trouble “seeing” the blades, either visually or with echolocation, especially at the tip, because at 60 rpm, the tips of the blades on commercial-sized windmills are going more than 300 mph.

Without bats there’s be no tequila, mescal, or bananas, because they’re the largest natural pollinator of the agave plant and banana trees.

They reckon the one colony of bats in Bracken Cave (near San Antonio) provides hundreds of millions of dollars of agricultural benefits to central Texas farmers annually.

The Surprising Way Wind Turbines Kill Bats. ( Not just killing endangered eagles, song and other birds.).

It is the pressure change—not only the blades—that wipe out birds and bats at wind farms.. As turbine height increases, bat deaths increase exponentially.

As the wind moves through a wind turbine’s blades, pressure drops behind them by five to 10 kilopascals (a pascal is a unit of pressure), and any bat unlucky enough to blunder into such an undetectable low pressure zone would find its lungs and blood vessels rapidly expanding and, quickly, bursting under the new conditions.

Pressure drops of as low as 4.4 kilopascals kill common lab rats and all the bats autopsied showed internal damage and bleeding consistent with this type of death, known as barotrauma. “If bats have a lungful of air as they fly through the air-pressure change, there’s nowhere for the air to go,”
Baerwald explains. “The small blood vessels around the lungs burst and fill the lungs with fluid and blood.”
