Harvard kids always were a little slow.
Wind works only when it’s really windy.
And then... There are repair crews on-site...
The other dirty secret of wind power:
Endangered bird pieces all over the place.
Wind guys aren’t allowed to collect the feathers,
but they do.
Wiondmills aren’t designed to generate realiable energy. That’s just the maguffin. Their real purpose is to pump taxpayer subsidy dollars into the pockets of landowners, mfgrs, and politicians.
Important study. They interfere with the normal action of the wind. The wind redistributes heat energy, a normal action than leads to equilibrium. Interfering with that is not good.
Windmills have become a symbol for the left. bammy allowed them to kill thousands of birds every day.
I’m pretty sure that the takeaway from this is that humans using any kind of energy at all, will cause global warming. The only way to save the planet is for a huge or complete die off of humanity. If you truly love the planet, you know what to do.
Harvard is nothing but a ‘snob factory’
windmills not only kills millions of song birds, eagles and so on, but uncounted millions of bats ... the insect kingdom loves windmills; the put windmills right up there with the elimination of DDT.
Save the Bugs!!! Build Windmills!
If the can’t be relied upon for constant power, something must be used to instantly take up the load. That something is called spinning reserve. It’s the gas and coal fired boilers that produce steam to turn turbines. Those turbines must be spinning all the time with a low load to be able to take up the slack and it takes a long time to fire up a cold boiler to produce 3000 psi steam.
I want to see the themodynamic analysis on this one. I say BS.
And further, after a cursory search on the authors’ publication history, I see nothing indicating the serious background in thermodynamics such a study would require.
Yep, seems that wind power being environmentally friendly is just HOT AIR.
i’ve often wondered how millions of 60-story windmills might alter the earth’s energy balance ... for one thing, there would be a whole lot of friction between those blades and the air ... not to mention massive disruption to the various normal wind flows here and there ...
My issue has always been the low efficiency of wind power. At best about 30% efficient. Would I invest in technology only 30% efficient with little if any hope for improvement?
It was in the beginning, no more than salesmanship that sold technology that went the way of the buggy whip close to 80 years ago. Rural electrification spelled the end of wind chargers back in 1930`s America.
Back then electricity was such a blessing that you hardly needed salesmanship, and as soon as it turned into AC power over power lines, you did not need a salesman to get people to dump their wind charger for the more efficient system.
This is from eight years ago:

I’m not sure this is valid. Our biggest argument is that the actions of man are minuscule compared to the actions of nature and the sun. Besides, air movement is caused by pressure differences between high and low pressure systems which again are caused by the sun. That windmills could affect the weather is about as preposterous as saying too many trees will slow the movement of air.
I remember some 40 years ago hippy vans often sported bumper stickers saying “Split Wood Not Atoms”. In those unenlightened days wood was considered a renewable resource with no concerns about global warming from burning it. Ironic how those forrests of windmills blighting our landscape are now being seen as contributing to the global warming hoax. Perhaps the corn ethanol boondoggle will soon be recognized for its contribution to the degradation of the environment.
“... by extracting energy out of the air”.
The one-word summary of that is “cooling”.
The gas passing through the turbine of a jet engine cools many hundreds of degrees in a small fraction of a second.
