World’s top bird killers beat out windmills big time

As if cats weren’t bad enough, humans have invented all sorts of torture devices for our winged friends. We’ve paved over their nesting sites to make room for Olive Gardens and have broken up their skyscapes with glass buildings and radio towers.

Then came the most infamous bird killer of all: the wind turbine. As you can see in the chart…these sky blenders top the list.

Just kidding. Windmills aren’t the biggest serial killer, but are instead the smallest threat to birds worthy of mention, on par with airplanes. Turbines are responsible for as little as one percent of the deaths caused by the next smallest killer, communications towers.

You would hardly know this by reading Twitter or scanning the comments on any news article about wind power…

The estimates above are used in promotional videos by Vestas Wind Systems, the world’s biggest turbine maker. However, they originally came from a study by the U.S. Forest Service and are similar to numbers used by the U.S. Fish and Wildlife Service and the Wildlife Society — earnest defenders of birds and bats.

No matter whose estimates you use, deaths by turbine don’t compare to cats, cars, power lines or buildings. It’s almost as if there’s been a concerted effort to make people think wind turbines are more menacing than they actually are…

It’s nice for wind-farm planners to take migration patterns and endangered habitats into account. But even if wind turbines were to double in size and provide 100 percent of our energy needs (both of which defy the laws of physics as we currently understand them), they still wouldn’t compare to the modern scourges of high-tension power lines or buildings with glass windows. Not even close.

The alternative to renewable energy sources like wind and solar is to burn ever more fossil fuels. Animals are threatened by those, too, including North America’s most common hairless mammal: the human. Roughly 20,000 of these moderately-intelligent animals die prematurely each year from air pollution from coal and oil, according to a study ordered by Congress.

And, of course, ignored by Congress.
