Yes, but wind turbines kill far fewer birds than large buildings, as long as they are not placed at stupid places such as bird migration routes. Painting one of the rotor blades black helps to reduce it further, especially for birds of prey.
Intelligente Windturbine: Totungsrisiko von Vogeln minimieren
Passing many wind turbines frequently the dead birds are an eye-catcher. Some volunteers pick them up and remove them. I wish those that want the wind turbines get a few in their vicinity.
The low frequency sound and the moving shadows they produce are annoying to many. It would be manageable if they weren't so large but the continuous system of tax payers money and investment companies wanting profit makes that they need to deliver lots of power so large, larger, largest.
BTW the black blade story I know but till now I haven't seen one in reality.

BMS under the surface is basically SCADA. Which is fine. SCADA is battle hardened and works, just not suitable to be connected to the internet 🙂. It's just no two installs are the same which makes C suite dreams of being able to compare buildings in their portfolio with a click of a button to make investment decisions impossible.
I hope to wake up one day with the idea to cut this gordian knot that will make me rich but I doubt I will. Pesky humans always make things difficult.

Paint it black
Although the effect is rather large, they needed to survey for a very long time and use a very sensitive test to get statistically significant results.

Probably also depends on country, location, temperature, average wind speed, earth magnetism and who knows what else. Will read tomorrow but it caught may eye that they painted the blade in place. Pfff that is really hard to do. When I am in Holland I notice a few things with wind turbines: high density and they're located very close to areas where people live or industry is situated so complicating factors.

I know enough to see a doomed project when put in front of me. Sadly my need to tell the truth has held be back in my current job 🙂 . But at least I can still find joy when I find clever technology to fill a real need.
Below one of the best Dilbert cartoons ever (in my opinion) which sums up what a lot of us see every day.

They painted it in place for the experiment, but you wouldn't do it like that for production of course. By the way, galliforms were excluded, but they could also reduce galliforms fatalities by high-contrast painting of the lower 10 metres of the mast.
If you can ever get your hands on the paint used for wind turbines don't hesitate. Very good stuff. No surprise: not water based.
And: they could/would etc. but in reality we see dead birds laying in the vicinity of grey painted wind turbines.

Roads, big buildings, wind turbines and so on.
This is fairly new research anyway, so we have to see what will happen in the coming years.

For the record: airborne wind energy means using kites or tethered glider aircraft rather than mills to pick up wind energy. It has many advantages and one major disadvantage: less use of raw materials, the wind is picked up at greater heights where the wind is stronger and varies less, fewer bird and bat strikes, no usable product on the market yet, only prototypes.
As far as I know it epoxy based. It is so good, that the Danes have started to use it to paint metal facade panels that are supposed to require no maintenance for the life span of the building, 50 years or so.
Yes. Nearly all wind turbine technology in one way or another comes from or originated from Denmark.
I like this. Kind of funny, but it makes sense.
I am not sure they will make it work. It is quite complex.
There is an amazing energy to harvest from jet streams. We do have the technology: Cables that can stand wind and their own weight, long enough, many kilometers to reach the jets.
In the 70s I worked at the French weather bureau at a service experimenting with very high altitudes. We were able to launch tethered balloons at 20km, so above the jet, to carry few hundred kilos of measuring instruments. The major issue was to cross through the jet. Then, the cable had to stand around two tons. That could only succed with low wind conditions.
Does everybody think it makes any sense to maintain our wasteful usage of energy and natural resources? It makes more sense for us to use as efficiently as we can, do away with disposable stuff as much as possible. In some cases, convenience is the entrance of the highway to misery.
Well I've never flown on a plane, I ride a bike to work ( steel frame ( no carbon fibre anywhere) and enclosed chain) , my job is refurbishing old stuff, phone is 4 1/2 years old, I haven't had kids, I only buy clothes that I'll wear, and I wear them until they've had it, and I use a class d amp. I guess the next step is going vegan.
