When I was a little boy is Sweden my father had a dear old friend that was so in love with birds and they with him that he had a great horned owl that came down and sat on his shoulder when he called. I was only three years old at that time, but the sight of this giant bird coming down from the big spruce tree is a sight I will never forget. Since then I have always enjoyed watching birds, normally soaring hawks, but especially eagles, rare as they may be.
Later in life I got gloriously saved and started reading the Bible, and one verse from the prophet Isaiah stands out :Isaiah 40:31 But they that wait upon the Lord shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint.
I am now at the stage in my life where walk and not faint seems pretty good, but following what goes on in the world is still exciting, even watching the birds.
The big talk is fighting climate change, and the prevailing political belief is that rising CO2 levels is its major cause, so no expense is spared to find renewable energy in the form of wind power, but at what cost?
The Eagle has landed in aerie
on top of a windmill – that’s scary.
Doesn’t know she will die,
whacked right out of the sky
from rotating blades unawary.
The idea of wind farming is to create sustainable energy.
Will the population of eagles and other large birds be sustainable?
They like to build their aeries on top of wind turbines, the highest structure in their territory.
It is estimated that the total bird kill by the year 2030 is going to be 1 million three hundred thousand birds. And that is if the Green New Deal is not implemented.
Is the large bird population sustainable even now?
This is a crane killed by a wind turbine blade. In parts of Ohio they have forbidden the turbines to run at night to protect a rare bat.
The allowable yearly limit for killing bald eagles by wind turbines was upped from 1100 to 4200 on Jan 17 2017, still under the Obama administration. The allowable limit for golden eagles is still 0. If the bird-kill exceeds the allowance, heavy fines are imposed, but that is just the price of producing clean energy. in 2013 Duke energy paid a 1.9 million dollar fine for killing 14 golden eagles and 149 other protected birds.

And it takes energy to produce energy. The cost of de-icing the average airplane is $1500. And that is without the helicopter.
And I am not sure about the former.
But there are potentially better solutions: The vertical wind turbine:
It has a somewhat lower efficiency than conventional wind turbines, but can produce electricity for about 4 c per kWh, so all is not lost. They do not kill birds, and can be made to function with wind speeds of up to 70 mph.
