@@Shnick in the UK, wind has now got so cheap that it is now the cheapest source of electricity in the uk, and is now forcing all coal and some gas plants out of business
@@danchang9976 But that isn't true. The only reason coal and gas plants close is because they are disadvantaged compared to special treatment that wind gets financially. First if wind energy is being generated then it gets first priority for use (it HAS to be bought by the electric companies) - so in windy weather the gas and coal plants have to 'stand down' and they get no compensation. But if it is so windy that all of it cannot be used then the wind companies get paid even though all the wind isn't used! This puts coal and gas at financial damage. Also what happens when the wind doesn't blow? We just had a week of that in UK (Nov 2020) - wind never got above 5% - it was only gas, coal and nuclear that kept things running, otherwise we have blackouts. Same every day actually it is gas (only) that enables power to ramp up as everyone wakes up in morning,
@@TheChrisEMartin yes, but it also means that consumers get cleaner air to breathe and lower bills as wind is now cheaper than gas and coal. Coal and gas is outdated tech, every utility company knows that and that’s why coal will be gone by 2024 at the latest and gas will follow suit in about 20-30 years. Nuclear provides a base load in our grid, followed by wind and solar. After that gas, biomass and hydro is used and if their is still a demand for more they use coal and move some gas plants over to peak demand scenarios where their output changes depending on volatility. It’s outdated tech, it’s going, don’t defend it it’s gone.

Very impressive turbines made by very skillfull people and their high tec equipment. 😀 Det er rigtigt flot klaret at i kan lave de kæmpestore vindmøller i Danmark.! 💕
Fun video except fore the recap style editing. Hate that. I just watched the same info from 12 minutes ago, I'm not a toddler, I can retain info for hours sometimes! lol Also, tons of info left out. How do they keep cool? What is a typical failure look like? What does a catastrophic failure look like? Show how the connect to the grid. Show how they stop, start, turn. How do they test the motors prior to shipping? How do they affect local Eco-systems? How about a map showing the amount of homes covered by a "typical" year's generation. Then show amount of space required for turbine-to-home ratio scaled-up. Meaning show space needed to power NYC or London in a typical year. How many, how much space at what cost, etc..? And how about recycling of old units? How much can be reused?
A wind turbine comes to the end of its lifecycle after about 20-25 years. While 99% of a turbine's parts can be re-sold and recycled, the majority of turbine blades are a challenge, so much so that they end up just being buried in a giant 'graveyard of blades' landfill. In the U.S. over the next four years alone that will be the fate of more than 8,000 blades.
It would seem that as technology grows, our footprint grows exponentially. Therefore, the BEST way to slow our destructiveness is to physically StOP consuming so much energy. The basics of life use to be rewarding. We've somehow lost our way.
Right - and he doesn't know how to pronounce epoxy ("e-poxy"), nor the difference between a screw and bolt. Still, it was very interesting despite the limitations of the script and narrator.
Absolutely everything those guys did in creating those blades in one piece was sheer genius. From the vauum sealed mold to getting epoxy into every nook and crany without air pockets. I expect they ran the hardener and epoxy through vacuum chambers before hand to remove all air pockets and the mixing would also need to be done in a vacuum. Iv seen so many experiments using epoxy and vacuum chambers and still they could not get great results as they tried to remove the air after mixing and putting into the mold. And seeing that guy tear fiber glass in half just with a knot. Unbelievable. I work with fiber glass. To see it snap like that. Its comparable to steel yet easily not as strong yet nothing reasonably priced and so light comes close so its a fair comparison in my opinion.
However there are huge landfills all over the place, like the one in Wyoming where the rotor blades are sent after their useful life, because they are not recyclable. Not much of the wind turbine is. The price of wind generated power is extortion, Ontario residents are being raped by their electricity suppliers. Calgary's biggest windfarm is due for replacement as it is too old and it will be headed for the landfills soon before being replaced with more of the same.
Yeah let's dump them all in your backyard to recyclable. Every Wind farm and Solar panel fiasco should have to post a $Billion dollar bond for the clean up of these eye sores!

In some places around the world, the word screw is used as a noun, and bolt is used as a verb, and vice versa in other places. For example: next we bolt it together with these screws.

Espectacular.. es impresionante como no pueden trabajar con vientos superiores a 6 m/s, cuándo en las zonas dónde se van a instalar es porque es muy ventosa...
@@dougankrum3328 People don't realize is how much coal & oil is required to fabricate, install and maintain them over that 20 years. That same coal & oil would have produced 5 times more electricity than the wind turbine will make in its lifetime.
@@SkullRaven Experience source, worked for Cant Name Wind for 10 years. Just to change ONE O-ring on one blade hub takes 300 man hours and 300 gallons of diesel and 180k$. There are 3 on each turbine. The units near the ocean have to be changed more often than inland but turbine output never even comes close to install and maintenance...and 5 times is a conservative figure. It doesn't even include eroded blade changes. Much more environmental harm then is allowed to be exposed to public on top of that.
10:52: "Each turbine has a rating of 7 megawatts per year"... um, no. The turbine has a rating of 7 MW. Stop. Power per unit time does not make any sense.
@Nader Abdel-Khaliq I'm not saying MW/year is right, but technically, acceleration is m/s^2, so having two units of time in the denominator isn't wrong. You can even have Jerk which is m/s^3
Hello, i'm not agree with you, it makes sense, , it's the second derivative of energy. So in ten years, this turbine will make 70 MW. it's Magic.! better than free Energy. Good remark however ...
You're right. I came to the comments for the same reason. A MW is a measure of power and they produce power or energy/time. 7 MW/year = 13j/s/s relates t nothing in the real world. Perhaps they mean 7MWy/y.
I guess they use post-tensioning steel cables to secure the tower, instead of bolting it together. It would've been interesting to see how the cables were tensioned and anchored to the foundation.
*Those cables were used to anchor the 83-meter concrete stacks. For the other steel sections that they added on the top to reach a height of 136 meters, were they also anchored to the concrete sections or just stacked up? I guess they were bolted to each other. Can anyone clarify that, please? Thank you.*
A machine screw is a screw or bolt with a thread type which accepts nuts (or other types of twisted on locking devises) possessing the same thread dimension. Example : a 6-32 x 1" screw would take a 6-32 nut..... and..... a 1/2-20 x 5" bolt would take a 1/2-20 nut. BOTH of them have "machine screw threads" and can be called machine screws. When the fastener in question has a shank diameter of 1/4" or larger, it's referred to as a BOLT.
The explanation for the use of the word 'screw' is that in German, the word 'Schraube' means screw and/or bolt and whoever made the translation was not aware of the distinction in English.
What is not mentioned is how hard it is to recycle the turbine blades, they suffer from stress fatigue over time. Basically, they get buried in special waste dumps just for this purpose.
It's definitely a negative, but not as big as you'd think. There's more than enough space for landfills, especially for non-toxic waste. The problem with landfills has been that things rot, producing gas which can cause problems when it seeps up. That's not a problem with turbine blades though. Recycling of composite materials is a big challenge that's not unique to wind turbines. I think switching to carbon composites, rather than fiber glass, will help a lot. It's all just hydrocarbons, so you could just burn it.
madaxe79 How exactly is it ironic? Please explain. I checked, and both carbon fiber and epoxy can be made from biological sources so the whole process can be carbon neutral. But even if you use petroleum.. what’s better? Burning tons and tons every day for energy? Or turn a bit of it into carbon composites, use it for decades and then burn it in a trash burning facility like those in Sweden, that then makes electricity and heats homes in winter? You could also bury it, of course, which is essentially just putting it back where it came from.
Audun Wilhelmsen I’m an engineering consultant, i travel to remote locations and solve problems. I did a job at a coal fired power plant around 3 years ago, and while i was there i learned a lot about the operation. There is virtually zero emissions from a modern coal fired power plant. What comes out of the top is pure water vapour, just hydrogen and oxygen, nothing else. All of the “bad” stuff is captured in the processing and is then used in other area’s, like fertiliser, road paving, brick making etc. there is no pollution. It’s a myth created by the green movement. In older power plants, yes absolutely, but in modern ones, nothing. The news always shows these big cooling towers with vast amounts of “smoke” come out of them, and they claim it’s pollution, when in actual fact, is extremely pure steam, nothing else. So until there is a way to recycle these turbines in a manner as clean as coal power, and also to manufacture them in a clean manner, then coal power is actually better for the environment. Also, i know you probably believe all the lies about carbon in the atmosphere, but the reality is that it is essential for plant life, and i have been involved in experiments with carbon dioxide enrichment for plant growth, and the experiment clearly increased plant growth significantly by enriching the carbon dioxide content of the air. That being said, there isn’t any carbon released from modern coal plants, it’s all captured used in productive manners. Have you ever gone to you local garden store and bought potash for your garden? Guess what potash is, it’s the heavy solids leftover from a coal fired power plant... Also bear in mind that, without burning coal you would have zero steel, or any metal for that matter. If you don’t know how steel is manufactured, i suggest that you do some reading, it is impossible to make steel without burning coal. Also, no matter how many of these wind turbines you build, they will never create a return on investment. The only way they can ever be viable is with subsidies, and the only way they can be subsidised is with tax. So we would be far better off financially and environmentally, to invest in clean coal power, than wind turbines. The only caveat being that we will eventually run out of coal. And we need all the coal we can get for steel making.
Georgw Marhevka. No they tight those cables with some special tools there so many industrial things made to this purposes I know cuz I been working not for wind turbines but for the electric industry so we use cable s and many things
I agree that it would have been nice to see the cables secured. Look up “post tension concrete” or something similar to get a basic idea of how it would be done.
It's a Similar procedure to tightening cables on suspension Bridges. As long as the cables are all equally tightened. It makes the structure very strong.
The Thor windfarm in Denmark will cost 15,5 billion DKK and have a output of between 800 and 1000 mw, it will probably be around 100 wind turbines, so its around 155 million DKK per wind turbine if the price of the connection to land is divided equally between each wind turbine.
@@flexairz It would be interesting to see a cost benefit analysis. Electric in Europe is very expensive, with the exception of France, which uses mainly nuclear power.
Yes i remember that. I think one of them jumped to his death and the other burned alive if i remember right. Horrible way to die knowing there is no escape
Blows my mind that the life of the blades is only 10-15 years and then the 35 ton 150' blades are left somewhere. How about in your backyard? Eye sore, junk,garbage, forever.

Must be nice to get paid to do a workout instead of paying to do one!
I wonder how much energy it takes to produce a wind turbine? From raw material to finished product including transportation.
It takes like half a year for a turbine to recover the energy invested on it's production and installation. They are really efficient.
And how much it costs to maintain. The industry claimed it would compete with other sources, but in the end, the customer pays the same regardless...

I've wondered that myself, and others have asked. But part of the whole wind-power is to reduce burning coal and oil....
@@dougankrum3328 People don't realize is how much coal & oil is required to fabricate, install and maintain them over that 20 years. That same coal & oil would have produced 5 times more electricity than the wind turbine will make in its lifetime.
@@Tadrjbs I'm sure you have a scientific source for that? I'm especially interested in that last statement.
@@SkullRaven Experience source, worked for Cant Name Wind for 10 years. Just to change ONE O-ring on one blade hub takes 300 man hours and 300 gallons of diesel and 180k$. There are 3 on each turbine. The units near the ocean have to be changed more often than inland but turbine output never even comes close to install and maintenance...and 5 times is a conservative figure. It doesn't even include eroded blade changes. Much more environmental harm then is allowed to be exposed to public on top of that.
It will never pay off.
хороший канал, молодцы
15:15 nice interior & sign design
Lovely and space to work on, well thought out
Fantastic documentary Thank You 🎃.
who else came from a video called “top ten wind turbine fails” and before that, came from “windmill destructed in storm”
😂😂 Yep
Haha how did you know?!
😂😂
Kate Malfoy me
Not me. Before this I was watching a documentary on the declining bird population in America. Somehow it switched me over to this video.
I searched up this video, but before that, I had watched those videos.
DREAM JOB WOW THANKS FOR THE VIDEO
10:52: "Each turbine has a rating of 7 megawatts per year"... um, no. The turbine has a rating of 7 MW. Stop. Power per unit time does not make any sense.
UNHCORE I came to the comments just for this same reason
@Nader Abdel-Khaliq I'm not saying MW/year is right, but technically, acceleration is m/s^2, so having two units of time in the denominator isn't wrong. You can even have Jerk which is m/s^3
Honestly can you please explain this to me? I’m not seeing the mistake.
Hello, i'm not agree with you, it makes sense, , it's the second derivative of energy.
So in ten years, this turbine will make 70 MW. it's Magic.! better than free Energy.
Good remark however ...
You're right.
I came to the comments for the same reason. A MW is a measure of power and they produce power or energy/time.
7 MW/year = 13j/s/s relates t nothing in the real world.
Perhaps they mean 7MWy/y.
Nice to watch
In Construction Simulator game the wind generator is a prized achievement, but is time consuming and difficult.
That was fabulous
That's 4 Hours and 20 Minutes at each station. Definitely a salute to 420.
Them are some pretty big screws!!! We call them BOLTS here in the Appalachia!!!
Image screwing one of those screws in your wall to hang a picture.
37:54 the voice-over is making him sound way more professional than he is lol
nice
I guess they use post-tensioning steel cables to secure the tower, instead of bolting it together. It would've been interesting to see how the cables were tensioned and anchored to the foundation.
@niels lund The method to show how the cables are tensioned and fixed down is omitted.
Good Engineering Documentary .Thanks
i guess we will never know how the cables get anchored lol
Seems like it's a trade secret
I wanted to see that instead of stacking the segments on top of one another.
*Those cables were used to anchor the 83-meter concrete stacks. For the other steel sections that they added on the top to reach a height of 136 meters, were they also anchored to the concrete sections or just stacked up? I guess they were bolted to each other. Can anyone clarify that, please? Thank you.*
i had totally forgot all about that part
A
I've been so bored that I'm starting to watch documentaries on how a wind turbine is made.. but I mean I'm not complaining they're so cool!
That Explains it, the most expensive Source of Energy 🤗🤨
And how many people do you think it takes to maintain a thermal or nuclear power station!?
not agree with u, more expensive is a coal\gas plant, nuclear plant. maybe solarplant too.
4 hours and 20 minutes to build each stage. Interesting number.
excellent documentary it has expanded the basic understanding of the complete precise engineering of these structures and build method.
I like smart people doing smart things
Amazing documentary!
Amazing and awesome.
BOLTS...... those fasteners are called BOLTS, not "screws".
I know! I thought I was the only one going crazy with guy kept saying screws!
I know that was driving me nuts. Screws to hold that heavy equipment in place. Lol
Stay safe bro
"machine screw"... look that up and wise up...
A machine screw is a screw or bolt with a thread type which accepts nuts (or other types of twisted on locking devises) possessing the same thread dimension. Example : a 6-32 x 1" screw would take a 6-32 nut..... and..... a 1/2-20 x 5" bolt would take a 1/2-20 nut. BOTH of them have "machine screw threads" and can be called machine screws.
When the fastener in question has a shank diameter of 1/4" or larger, it's referred to as a BOLT.
The explanation for the use of the word 'screw' is that in German, the word 'Schraube' means screw and/or bolt and whoever made the translation was not aware of the distinction in English.
Superb
What is not mentioned is how hard it is to recycle the turbine blades, they suffer from stress fatigue over time. Basically, they get buried in special waste dumps just for this purpose.
If they can't be recycled in some way, that is a big negative.
It's definitely a negative, but not as big as you'd think. There's more than enough space for landfills, especially for non-toxic waste. The problem with landfills has been that things rot, producing gas which can cause problems when it seeps up. That's not a problem with turbine blades though. Recycling of composite materials is a big challenge that's not unique to wind turbines. I think switching to carbon composites, rather than fiber glass, will help a lot. It's all just hydrocarbons, so you could just burn it.
Audun Wilhelmsen hahaha... just burn the hydrocarbons, how ironic
madaxe79 How exactly is it ironic? Please explain. I checked, and both carbon fiber and epoxy can be made from biological sources so the whole process can be carbon neutral. But even if you use petroleum.. what’s better? Burning tons and tons every day for energy? Or turn a bit of it into carbon composites, use it for decades and then burn it in a trash burning facility like those in Sweden, that then makes electricity and heats homes in winter? You could also bury it, of course, which is essentially just putting it back where it came from.
Audun Wilhelmsen I’m an engineering consultant, i travel to remote locations and solve problems. I did a job at a coal fired power plant around 3 years ago, and while i was there i learned a lot about the operation. There is virtually zero emissions from a modern coal fired power plant. What comes out of the top is pure water vapour, just hydrogen and oxygen, nothing else. All of the “bad” stuff is captured in the processing and is then used in other area’s, like fertiliser, road paving, brick making etc. there is no pollution. It’s a myth created by the green movement. In older power plants, yes absolutely, but in modern ones, nothing. The news always shows these big cooling towers with vast amounts of “smoke” come out of them, and they claim it’s pollution, when in actual fact, is extremely pure steam, nothing else.
So until there is a way to recycle these turbines in a manner as clean as coal power, and also to manufacture them in a clean manner, then coal power is actually better for the environment. Also, i know you probably believe all the lies about carbon in the atmosphere, but the reality is that it is essential for plant life, and i have been involved in experiments with carbon dioxide enrichment for plant growth, and the experiment clearly increased plant growth significantly by enriching the carbon dioxide content of the air. That being said, there isn’t any carbon released from modern coal plants, it’s all captured used in productive manners.
Have you ever gone to you local garden store and bought potash for your garden? Guess what potash is, it’s the heavy solids leftover from a coal fired power plant...
Also bear in mind that, without burning coal you would have zero steel, or any metal for that matter. If you don’t know how steel is manufactured, i suggest that you do some reading, it is impossible to make steel without burning coal.
Also, no matter how many of these wind turbines you build, they will never create a return on investment. The only way they can ever be viable is with subsidies, and the only way they can be subsidised is with tax. So we would be far better off financially and environmentally, to invest in clean coal power, than wind turbines. The only caveat being that we will eventually run out of coal. And we need all the coal we can get for steel making.
Hola soy de Argentina q,bárbaro tecnológico extraordinario
They’re bolts, not screws
hi tensile blts
Bolts are screws
I said the same thing. Lol
They could be set screws if the thread goes all the way down to the shoulder, they’re only bolts if there is a decent shank
@@lollollollollolrofl Agreed
What a interesting video.
How do the wires going through the tower get tightened? looks like they left that out.
Georgw Marhevka. No they tight those cables with some special tools there so many industrial things made to this purposes I know cuz I been working not for wind turbines but for the electric industry so we use cable s and many things
I agree that it would have been nice to see the cables secured. Look up “post tension concrete” or something similar to get a basic idea of how it would be done.
It's a Similar procedure to tightening cables on suspension Bridges. As long as the cables are all equally tightened. It makes the structure very strong.
Company secrets 😉
A magnificent documentary,Thankyou for providing it for a most informative experience.😎🇳🇿
KINDLY ALSO MENTION EACH WIND TURBINE PRICE WITH INSTALLATION.
If you have to ask, you can't afford it...
About 1.3 million dollars per MW of capacity. Most wind turbines are built for 2.5 MW capacity.
The Thor windfarm in Denmark will cost 15,5 billion DKK and have a output of between 800 and 1000 mw, it will probably be around 100 wind turbines, so its around 155 million DKK per wind turbine if the price of the connection to land is divided equally between each wind turbine.

Absolutely fascinating. Loved it. Has anyone calculated the energy to make one of those? How long to pay back the "embodied energy"?
The lastest Wind turbines are Suppose to recoup construction cost and energy in under a year. And then last another 25+ years
They never will recoup all the energy that went into them. Impossible.
@@flexairz you have some information to share on the subject? Or is that just your opinion?
@@johnv341 inflation always seems to fenagle its way into even the deepest of pockets. I cut mine off 😂
@@flexairz It would be interesting to see a cost benefit analysis. Electric in Europe is very expensive, with the exception of France, which uses mainly nuclear power.
That’s a lot of resources for maybe 1200 households.
I remember seeing the picture and article about the two engineers who were caught on top of one of these as it caught fire :-( Terrifying.
Yes i remember that. I think one of them jumped to his death and the other burned alive if i remember right. Horrible way to die knowing there is no escape
Yeah they were seimens employees in Denmark. Its recapped in all of seimens training now

Blows my mind how us humans are capable of building all this technology
Blows my mind that the life of the blades is only 10-15 years and then the 35 ton 150' blades are left somewhere. How about in your backyard? Eye sore, junk,garbage, forever.
I'm a big fan of this video *wink wink*
Look at all the equipment fed from fossil fuels it takes to put up one of these green machines.makes total sense!
You gotta start somewhere. If you don't start you will never get there.
@@bradlambert1679 ha but all these greenys want fossil fuels to go away,no starting anything green with out fossil fuels!
????? Some people really shouldn’t be on the internet
Great
Wind turbine is expensive toy with low sufficiency . It is social adverts for "greens"
😊 😁 scrap farms...
Funny then why are massive companies investing large amounts into wind. Dont listen to everything you see on the internet
@Vladimir Birukoksukker - hmm.... let's see... Vestas, revenue for 2019 is 12.15 BILLION EUROS, which is over 14,000,000,000 USD (BILLION, son) and they a strictly a manufacturer, seller, installer, and servicer of wind turbines.
Thanks very much....!
