@@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

[@TheChrisEMartin]

@@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,

[@danchang9976]

@@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 Coal and gas is outdated tech, every utility company knows that and that’s why coal will be gone by 2024 at the latest and gas will follow suit in about 20-30 years.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 It’s outdated tech, it’s going, don’t defend it it’s gone.

[@marby602]

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.

[@RobertSeviour1]

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.

[@madaxe79]

Lane Shurtleff if that bugs you, you’re part of the problem. Zane H If you call them bolts, then thats fine, I normally would too, however, in Europe (and Asia) they call them screws. 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. I repair very large mining equipment and spent years manufacturing it, and the general rule of thumb in our area is that a bolt is used as an assembly with a nut and washer, while a screw doesn’t use a nut, it is “screwed” into something, however when we deal with our German counterparts, they just call everything with a thread, a screw. So my original comment still stands: in your little bubble, they’re bolts and everyone who disagrees is wrong, but in the real world, it doesn’t matter. Q. What are you if you are on an incline plane, wrapped helically around an axis?

@The Curious Mind I can - where I live we are not far away from the biggest onshore farm in the UK, where they have both Siemens and Alstom turbines. You can't hear them at all until you are fairly close, 50 metres or so, is the first thing I will say. There's a hum from the generator and electronics, quite similar to what you hear if you're next to a transformer. You a low pitch "swoosh" every time a blade passes by. Also on these ones they drilled a small whole through 1 blade on each turbine which gives a little whistle - that discourages birds and bats from flying too close. The other noise you might hear is a knocking. That's from the guy trapped inside ;) no what that is the yaw drive. Because the motors are very underpowered for the mass at the top the turbine changes direction very slowly, and that noise is just the yaw gear travelling from tooth to tooth. Hope that helps!

How much energy is needed to manufacture these "Wonderful " Machines? And what is the output Vs input ?? And what is the lifespan of these "wonderful Machines" How are the used parts recycled?? And how many birds do they kill??

[@MrBurtonboy14]

There is a lot to unpack here but ill do my best. Massive amount of energy is used to manufacture everything from the electrical components on the interiors to the fiberglass blades and steel cans. There is not input to the towers except during construction. Manufactures all build varying output turbines but most fall around 2-4 MW which usually is about 6 million kWh every year (that's one turbine). I personally had done repowers on some of the first turbine installed in Oklahoma back in 1990ish so in practice as long as the steel cans hold structural integrity you could see one standing for many years while updating the interiors(not something most wind farm/park owners do). Classically all the metals are recycled and the electrical components are scrapped as well. Fiberglass cant really be recycled and blades cant be reused considering they are made in sets and balanced specifically for one another(aka if you brake a blade and it cant be fixed by a fiberglass tec. your THROWING AWAY all three blades, they cant be recycled). And as for the birds the numbers are exceptionally low considering. Most migratory birds will literally change their seasonal flight paths to avoid farms/parks. Hope this sums it up for u Cheers

[@brucefrykman8295]

@@MrBurtonboy14 Not all bird deaths are equal Wind turbines kill endangered raptors and these deaths are vastly under reported due to monthly vs daily collection of carcasses. Scavengers carry most of the carcasses away from the kill sites before they are inventoried.

[@MrBurtonboy14]

@@brucefrykman8295 This is not true. Blades have built in sensors on most models and need to be inspected basically immediately after an impact. Failure to do so could result in catastrophic failure of the blade structure which leads to the entire turbine ripping itself to pieces (roughly between 2.5 and 3.8 million dollars, not including labor). Which means we know exactly when birds hit turbines and we have extremely accurate data on the topic. In regards to not all birds deaths are equal. You are right not all birds deaths are equal but a study done in 2014 shown wind turbines kill an estimated 140,000 to 328,000 birds each year in the US. The same study also shown collisions with power lines in the US numbered 12 to 64 million. These are just the facts do with them what you will.

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.

Everything is fantastic, but I would also like to see a documentary about what happens during use or kills birds, how often they work how much energy they produce for how much they sell and then what happens to worn out windmills.

[@Wookey.]

a 2MW turbine on a tall tower like this will have a capacity factor of about 30-35%, so will produce 700kW average output, or 6.13 GWh/yr worth about £200,000/yr worth of electricity (at wholesale prices). They have at least some output about 85% of the time. They can kill birds, and more often bats (because the blade-tips travel at over 100mph), although rates are very low in comparison to other sources of human-induced bird mortality such as cats, cars and buildings (in general - some migratory routes have been deemed unsiutable for wind turbines because putting them there would cause unnaccepetaby-high bird mortality). When they are worn out the tower +foundation is often re-used for a larger, more modern, more efficient turbine: i.e. 'repowered'. Old turbines (and towers) are recycled (except blades, which can be, but mostly aren't currently - I expect that to change due to both technology and regulation.

[@zorkpl]

@@Wookey. Thank you for your comprehensive answer.

[@iareid8255]

Physically large with a tiny power output. Not only that, the power developed is on a cube law to wind speed so a small drop in wind gives a very large drop in power. Not really a good idea, they only work with proper generators to support them. They will not work by themselves in a grid situation.

[@Wookey.]

And yet some countries/states are now over 50% windpower average over the year, and 100% windpower some of the time. Their grids have not collapsed and grid operators are _much_ more bullish about what maximum possible wind penetrations are. A small amount of grid stabilisation from batteries and inverters is all that is needed to keep a stable grid. It seems increasingly clear that the large majority of generation is going to be wind and solar, despite the variability.

[@iareid8255]

@@Wookey. Who has a grid with ath amount of wind input? If you have 100% wind, how do you balance demand and supply, wind doesn't load follow? Batteries can aid frequency but in times of transients that is what actually counts. Small capacity batteries will be swamped.

[@WindTechInsights]

@@iareid8255 UK, Denmark has enough wind capacity for 100% wind, however the every day production is a mixture always. Denmark import electricity from Norway (100% water power plants) and Germany when it needs more. Only 100% wind is not possible, the production must always be a mixture, that is what they call energy mix.

[@WindTechInsights]

otherwise there would be only wind everywhere :) simple because it is cheaper to make a wind turbine capacity then making coal fired power plants...

[@iareid8255]

@@WindTechInsights Yes that is basically what I said, capacity is a poor figure to use where wind is concerned as it's average out put is between 25 to 33 %of capacity. Denmark could not have as much wind generation without Norway, it just would not work. It is the reason that their electricity is expensive, sell cheaply to Norway when ther is an excess and by dearly from NOrway when there is a dearth. It still does not overcome the technicalities of no inertia and asynchronous generation. Also lower short circuit levels with a lot of wind power which affects, or rather makes the protection systems much harder to operate effectively. A lot depends also on the type of load on the grid. If you have a large amount of heavy industrial use or not is a factor as heavy plant drags the voltage down on starting equipment.

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.

According to the International Journal of Sustainable Manufacturing, the time for a 2 Megawatt wind turbine to generate the amount of energy spent in manufacturing and installing it is 5 to 8 months.

[@RussellChapman99]

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.

[@ralphedelbach]

If they can't be recycled in some way, that is a big negative.

[@auspiciouslywild]

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]

Audun Wilhelmsen hahaha... just burn the hydrocarbons, how ironic

[@auspiciouslywild]

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.

[@madaxe79]

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.

I am wondering why Texas has not attached onto wind turbines as a source of energy. California has done this especially north of Barstow on I-10. I am thinking privately owned property in rural Texas may pose problems. I would appreciate input from anyone.
