Because of our long evolutionary history on our little space rock, we have developed, as a species, a sort of collective subconscious. While Jung explains it best in his many books on the subject, the idea put very simplistically is that we have a sort of genetic hive mind that allows us to retain some general ideas, feelings, and instincts.
And while some of us like to think that we’re going through our lives without preconceptions, they are actually over us every single day. For example, due to the dark color and mouse-like features of bats, they’ve long been associated with the occult or are just considered plain creepy.
Bats versus turbines
Despite our preconceptions, out of the very numerous species of bats, only some are actually in any way dangerous. In fact, most of them are just cute, fuzzy, small flying creatures that can pretty much only harm flies and other insects which they eat. Some even eat mostly fruit, such as the fruit bat.
But with the rise of technology, bats seem to have developed a nemesis of sorts. Each of them killing around 70 bats every year, wind turbines are wreaking havoc on bat numbers. And seeing as some bat numbers are dropping rapidly, measures have to be taken in order to stop the massacres.
According to a new study from the place where the bat wind turbine mortality is the highest in the country if no not the world, the Appalachians, experts finally managed to conclude that the hoary bats and the red bats are the two species most affected by the deadly wind turbine blades.
Flying rodents need protection
While the number of red bats has only recently been calculated at hundreds of millions, the unfortunate hoary bats only number in the tens of thousands. And with dozens killed every year by wind turbines, the creatures’ future is looking kind of bleak. So what can be done about this?
Well, there are a couple of things power companies could go for to reduce the yearly death tolls. One of these techniques is called curtailment, and some power companies are known to occasionally use it. What it implies is to simply turn off the turbines for the occasional single night during which a bat migration is announced. This would save countless lives in the ranks of the flying mammals.
A second practice would be the implementation of a newly designed type of turbine. These shrouded turbines, as they are called, have a more compact design and some bonnet-life flaps ringing their perimeter. They are especially designed to boost efficiency, deter the creature’s course away from the blades and sit below the animal’s flight path.
