Not sure whether I just wanted and planned to post this some days ago, or actually did post it in some thread, at least I do not find it. So I post it here (again?). Interesting, desillusionizing.

"The westerly wind weather, which has provided northwestern Europe and Central Europe with sufficient precipitation for as long as we can remember, has been artificially switched off." says the historian and author Dagmar Jestrzemski. She has been investigating the drought problem of the past few years and has found a possible surprising cause. The westerly wind weather conditions, necessary for rain and plant growth, are increasingly absent. She sees the high density of wind turbines in Germany as responsible, which causes increasing problems with moisture transport in the lower atmosphere: -

Declining wind speeds for Germany are testimony to the results of a study published by Deutsche WindGuard on October 5, 2020 on behalf of the Bundesverband WindEnergie e.V. with the title "Full load hours of wind turbines on land - development, influences, effects". - According to this, the mean specific nominal power of the wind turbines (MSN) - the ratio of the nominal power of the wind turbines to their rotor circular areas is measured - steadily deteriorated in Germany from 2012 to 2019 and this, although wind energy has been more and more effective for 20 years and now from heights significantly above 200 m is skimmed off. -

The cause of the trend, which is worrying for the wind industry, is the decline in the mean wind speed in Germany, which has been measured for decades. Despite the hoped-for increase in energy yield due to the steadily increasing effectiveness of the wind turbines, the MSN in Schleswig-Holstein fell by around 30%, in the north by 25%, in the middle by 23% and in the south by 26%. Specifically, it concerns the decrease from 420 watts / sqm to approx. 295 W / sqm in Schleswig-Holstein, from 400 to 300 W / sqm in the north, from 380 to 270 W / sqm in the middle and from 380 to 280 W. / sqm in southern Germany. -

The study by Deutsche WindGuard shows a relatively stronger decrease in the mean annual wind in those regions where the wind blows comparatively the strongest and the wind energy is accordingly most intensively siphoned off. For the whole of Germany, the result of this study establishes a clear connection between the declining wind speed and the massive extraction of wind energy from the atmosphere: -

The wind farms fall victim to an atmospheric calming wind that they have generated themselves. - A study published more than two years ago by the “Institute of Atmospheric Physics, the Chinese Academy of Sciences” (Huang et al.), Beijing, came to the conclusion that the continuous decrease in atmospheric wind in the northern hemisphere is a widespread and widespread is now a potentially global phenomenon. The phenomenon is also known as “global terrestrial stilling”. In China, the country with the world's strongest wind power capacity, the regions with gigantic commercial wind farms in areas with large wind energy reserves consistently recorded the greatest declines in near-surface wind energy. In Europe too, 50 percent of the stations observed have lost more than 30 percent of the wind power potential since 1979. -

This trend, which has persisted for 40 years, is in contrast to the "investigations of the geostrophic winds over the German Bight since 1880. This revealed periods of weaker and stronger winds, between which 20- or 30-year decreases or increases are discernible". - Accordingly, a reversal of the declining wind development should have occurred long ago. This is by no means indicated. A factor must therefore be effective here that prevents the reversal of the negative wind trend, so that the continuous decrease in mean wind speeds continues. -

For Schleswig-Holstein there is also the fact that, according to the IWR Wind Yield Index, the wind has decreased particularly strongly on the coast, between 2008 and 2017 by approx. 7%, in the interior of the country by only approx. 5%, both compared to the decade before. The greater decrease in wind speed on the coast - compared to the inland - is likely to be attributable to the wind shading effects of the North Sea wind farms and the particularly numerous coastal wind farms. -

Obstacles do not directly draw energy from the wind. Only the turbulence that occurs there withdraw energy from the air flow. In contrast to this, a significant part of the wind energy (max. 59.3%) is directly siphoned off and consumed when generating wind power. The slowed and turbulent currents (dragging wind) in the lee of the wind turbine also withdraw energy from the wind - on land up to a length of 30 km, over the sea up to 100 km. Both effects inevitably slow down the wind across large regions. -

The siphoned off wind, which is increasingly lacking in more and more locations and therefore to an increasing extent in regional and global wind systems, has catastrophic consequences: Less wind = less rain = drought and dry soil, forest death, crop losses = less spread of pollen and seeds = less rejuvenation of the Vegetation. -

In Germany, with its 30,000 inland turbines and around 1,600 offshore wind farms, there are hardly any regions of sufficient size for the natural atmospheric currents to recover from the braking effect of the wind farms. As a result of the strong concentration of wind farms, the warmer soil air in these regions can no longer rise at night, so that a comparatively higher rise in temperature was provoked in Germany (Confidential communications from politics, business and investment, No. 4356, regarding: D. Keith & Lee Miller, Joule 10/04/2018). For 2018, a temperature increase of 0.24 ° C was calculated, which is above average in a European comparison, which is attributed to the 30,000 wind farms on land. -

In January, German Watch announced: Germany ranks 10th among the countries most affected by climate change (= temperature rise, drought). Why Germany of all places? Climate activists ask themselves, who simply do not want to consider the real cause. Answer: Because in this country, in relation to land and sea area, most wind turbines have been installed worldwide. Weeks or months of drought have been the norm here in the Hamburg area for a number of years almost all year round. As a result, we notice an unprecedented calm in the formerly windy north, now also in autumn and winter. No more heavy rain and “bad weather” only for a few days - these are part of the symptoms of the dwindling wind. -

Especially at night, the wind farms on land prevent a drop in temperatures. The warming caused by static permanent high pressure areas over Germany did not stop at the borders. This is confirmed by a message from the Royal Netherlands Meteorological Institute dated January 5th, 2021: “The temperature in the Netherlands has risen by an average of 1.1 ° C over the last three decades (!!). That is more than twice as much as the increase in the global average temperature in the same period. "-

Wind brings rain. Site-specific withdrawal of wind energy has already intensified climate change instead of containing it: Weakened Atlantic low pressure areas during the growth period free the space for static high pressure areas and thus cause an existence-threatening loss or even a drying up of precipitation as in 2018 in Germany and some neighboring countries. The fact that this connection is still not recognized or underestimated by the responsible body is based on the fatal misconception that wind energy extraction is not harmful to the climate, regardless of the extent. -

Wind and water are two inseparable resources! Politicians, scientists, journalists and those interested in the wind industry also know that the siphoning off of wind energy is related to the increasingly pronounced wind calming. Actually, those responsible should be clear that a continued exponential expansion of wind energy, as it is planned on the basis of the European "Green Deal", means switching off the natural wind balance, which will very soon lead to a catastrophe - if the catastrophe does not already exist for us has caught up! The drought that has suddenly become virulent over the past three years should serve as the very last warning to all those responsible. -

The temporal connection between the exponential expansion of wind power capacity in Germany and the outbreak of the severe drought - with an unprecedented water shortage during the growth period - 2018, 2019 and 2020 to be taken seriously: 2010: 26.86 GW, 2014: 38.16 GW, 2017: 53.3 GW each on land, 2019: 61.3 GW and 2020: 65.3 GW wind power capacity on land and offshore. - Regardless of this, politicians and the wind industry are planning a further exponential expansion of WE capacity on land and above all offshore: 300 GW in the North and Baltic Seas alone. That would undoubtedly mean the death of the marine environment in the North Sea and large parts of the Baltic Sea. In fact, expanding the WE would act like a fire accelerator for the drought that caught up with us in 2018. -

In Germany and all of Europe there is still a taboo regarding cause and effect, i.e. a refusal to recognize the connection between the exponentially operated wind energy extraction and the wind lull that is provoked by it. The weakened wind, in turn, intensifies climate change by freeing up space for static high pressure areas and weeks of droughts for most of the year. [Guest author Dagmar Jestrzemski]

"For every action there is an equal and opposite reaction"

WOW!! Here in Australia all we ever seem to get is windy days, often gale force!! :doh: Would love to see some calm days! :hmmm:
As E says maybe the Earth shifting on its axis has caused this differing on the 2 hemispheres. I remember the good old days were cooler and less windy. :yep:
(Maybe I was less windy too!! :oops:)

Living on the coast and next to a large river I often wish we had less powerful winds.

"Eifelon" has twisted scientific findings to make it fit their ideology. It is connected to the EIKE, does not pubish in scientific circles and is generally said to promote lobby work for the denial of climate change; it is also connected to the AfD.

"Nach Angaben des Bundesumweltamtes verbreitet EIKE Thesen, die dem wissenschaftlichen Konsens widersprechen.[4] Nach Auffassung von Gabor Paal, einem Journalisten des SWR, hält kein Beweis und kaum eine Behauptung der Klimaskeptiker von EIKE einer Nachprüfung stand.[5] Zum großen Teil stützten sie sich auf Rest-Unsicherheiten in der Forschung, die es tatsächlich gibt oder arbeiteten mit Diffamierungen einzelner Wissenschaftler. Laut EIKE-Pressesprecher Hans-Joachim Lüdecke brauchen wir ohnehin keine Klimaforscher, schließlich gebe es keine wissenschaftlichen Beweise dafür dass CO2 die Atmosphäre aufheize.[6]

In den Erläuterungen auf der eigenen Webseite zum Fachbeirat ist von einer engen Verbindung zwischen EIKE und "führenden Wissenschaftlern" die Rede. Zu den Mitgliedern der EIKE-Gremien (Leitung und Fachbeirat) gehört jedoch kein einziger Metereologe oder Klimatologe, der aktuell an einer wissenschaftlichen Forschungseinrichtung oder Universität tätig ist (Stand: 10/2019)."

It took a minute to find this on the web. I would indeed wish the smelly Eifelon winds would die down :03:

Blödsinn, Catfish. The political polarization is exactly the other way around.

Dagmar Jestrzemski, AFAIK, belongs to the grassroot/civil right movement "Windwahn" that represents civil protesters against the demolition of the landscape with ever more windmills, and the issue of infrasound. They explicitely have attacked propagators of the pro-wind lobby for their closeness to known rightwing extremists and have protested also against their own defamation by pro wind and fridays for future propagators attacking their resistance to ever more windmills with even Nazi-jargon like lies and phrases.

In germany, everybody not being fire and flame for the politically ordered Energiewende and daring to ask critical questions about it and not totally agreeing with the wanted narration of climate change, is fair game for any hobby hunting and political witch burning. Even well-founded scientific doubts and theories get mercilessly gagged, mobbed and persecuted by the mass media if they are not fully in line with the officially wanted narration.And that is an international problem, not just a German one. Ciomate scinece hvae become anything but a soicnec,e they have become a relgious dogma, and everybody not fully in compliance is a heretic who gets hunted down.

The probklem with the wind has a close equal. The sam rpibek,ms are to be foudn i rivers where the yhve buold severl water powerplants. The floating speed of the water is being reduced, whgcih is a prbklem namely in severla Chinese regions where the ecological consquences in some regions are immense.

And yes, I am convinced we need nuclear energy, and solar and wind power will not do the trick for us, are too unstable. The demand for energy will not shrink - but it will grow. Heck, I have invested a signficant amount of money into preparations for energy system breakdowns just being caused by this Energiewende-madness, so you can bet that I am bloody serious about it.

A sentiment your neighbors downwind likely share. :arrgh!:

@ Skybird you have made another thread about this-You made it back in March

re Skybird

I do not like those wind turbines, for a lot of reasons, from area consumption to the looks of it, to killing birds flying into the props' paths, but they do work energy-wise. There were already a few days where countries were entirely fed with alternative energy systems for a short time, it is not enough to support all the factories and single households under any but perfect (for turbines) weather conditions; but then wind turbines are not really smart when it comes to providing energy. They are a solution for flat lands, if you have mountains you can use hydrooelectric power, but even then you have long distance wiring with the resulting power loss.

Energy consumption can be reduced by building smarter technology and a change of basic and insular solutions, like using hot water and sun collectors instead of roof tiles, combined heat or other small insular power plants feeding the general electrical net when the single household is idling and so on, but it takes time and the will.
You do not need 220 or 110 Volts, most can be run with 12, but of course you need the power I, the Ampère. A good idea would be to use nuclear energy maybe in very small facilities, or even better switch it all to hydrogen. The latter can be stored or produced in quantities you temporarily need via fuel cells. You could even use your 100-year old Otto engines in cars without major changes, with only warm, water-saturated air leaving the exhaust.

But you need the will, and the human will ist still to exploit everything, to use it up to the last drop, to sell and distribute energy centrally and controlled by companies or lobbied government, casually ruining the environment. They always speak of the "environment" as if it only concerns something around humans are not a part of, but you should know better. You destroy the "environment", you destroy yourself.

Building and maintaining insular solutions is also not cheap, but so is maintenance and feeding of coal plants. You do not need big overland wiring, so not much power loss expected due to electric resistance over short distances. And nuclear energy produced in large reactors is also again the old centralising of energy hat has to be distributed over long distance, being also susceptible to terrorism or strikes in a war. Why all that? The future is the present, you have the solutions.

Ha, I knew it! It feels strange when you stand beside yourself, watching yourself making a cup of coffee. It seems I need more caffeine in mine.

Its not good a development, but it seems mankind does never stop without hitting the wall hard first.

Our once world-class powergrid in Germany is just a shadow of its former state. We have become the eiüpicentre of every deepending and ever more often happenign instabilties and frequences fluctuations in the European powergrid. Our idea of how to run an altenrtaive system does nto work so far. And thigns get worse and ever more threatening. Now they want to even bring car batterie s into stabilising the national powergrids.

The Germans and there ever more perfectionist plans... For porpjects... For intentions... l For the future... I would already be satisfied if their plans would just pragmatically work, for a change.

As a matter of fact they canbot even build a road straight and even anymore. Come to my place and see the street where I live, it was redone in the year I moved in, 21 years ago. 2-3 degree camber when it was done. after the fixing, 4-5 degrees camber.

The world does not want to be saved by visionaries fixing things in this fashion. Nor does it need such a visionary's plans.

Even the eu has listed nuclear energy as "green". Maybe not becasue it really is green, it dependfs on how youz look at it. But because it was understood that we cannot run the future without nuclear energy, as the Germans daydream. The Austrians have plenty of mountaneous rivers. The Swedes hav eplenty of forest per head of population. Germany has not the wind of the antarctic, nor the sun of Northern Africa.

We are the epicentre of Europe' new and completely unnecessary energy turnmoils. Last time we almost brought down the contionetal (!) powergrid, was early January this year. Just the last incident in a by now long chain of incidents, each later one having been more threatening than the ones before.

"Eigentlich ein guter Plan - nur funktionieren müßte er." Plans not taking reality into account, cannot work and never will work.

Yes. So there is a certain kind of truth, but no one wants to acknowledge it. How do you think mankind reacts to a future that promises a falldown? They embrace it. Full ahead.

I've tried to picturing how the winds looks like when it has passed one of these windmills.

I'm picturing picture from aircraft science-Don't know if it can be used.
