  • Exceptional Engineering: The Making of a Wind Turbine | Engineering Documentary
    Electricity harnessed from wind has become the second largest source of energy in Germany since 2017 - and has thus out powered nuclear and coal. Nearly 30,000 on- and off-shore wind turbines are operating throughout the country, covering approx. 19 percent of energy consumption. Our report follows the construction of a new wind power plant in Falkenthal in Brandenburg. Once installed, the windmill will be 179 meters high, supplying up to 5,000 households a year.

    Wind / solar are horrible sources of energy for powering the nation with current technology. When compared to output (KwH) vs eco foot print it not much if any better than burning coal. There are a lot more variables involved than the supporters of this technology want to admit too. Nuclear power is by far the cleanest form of energy per KwH. Nothing else can come close at this time. Even with all the nuclear disasters that have occurred factored in (not including nuclear used in war) it would still beat out all other energy sources by a large margin. There are far better sources of energy than wind / solar but any new ideas will get shut down if it were to threaten the wind / solar industry. We can only solve the world’s energy issues and do it quite quickly, once the people are put ahead of profits. In the mean time corporations put profits ahead of the people but the people must carry the burden. They want YOU to feel bad about driving your car or “not doing your part” space ship earth and what not. All while technology to release us from fossil fuels and revolutionize man for better has existed for decades but is withheld because instead of 100billion they make only 10billion just an example but u get the point.

    Do these wind turbines last long enough in order to pay for the cost it takes to construct them before they wear out.

    • Joe Brake

      Highly unlikely, unless they will be replaced the same way they are being constructed now; that is by using almost entirely so called fossil fuel energy. No possible way they could ever do it with wind or solar.

    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.

    • Túri Tamás

    • I A Reid

      @Túri Tamás
      Why on earth would any government put such a high tax on a basic necessity. Germany, which also has high electricity prices has vast numbers of diconnections becaus epeople cannot pay their bills?

      Which ever way you tailore the design of a wind turbine, e'g', maximum out put at the average wind speed for the area, wind speed varies and so output with it's cube law relationship. Which ever way you look at it, wind is a poor way to generate power for a grid. You cannot make a silk purse from a sow's ear.

    • Túri Tamás
      Túri Tamás 22 दिन पहले

      @I A Reid actually the cost of producing in Denmark is the same like in Romania for example....what makes it more expensive is the 150%tax on electricity. Offshore wind turbines we build has much higher availability, and the powef curve is also impressive as the turbine can produce at full capacity in relativly low wind

    • I A Reid
      I A Reid 22 दिन पहले

      @Túri Tamás

      Sorry but that is not so.
      The point about coal plants is once built you can rely on virtually 100% output as required. (When you look at coal plant availability you must factor the routine maintenance down time in summer when demand is low. When necessary coal produces.)
      Wind also needs, very often expensive infrastructure to be added to the cost, the requirement for balancing plant, often running uneconomically, and for back up stand by plant. These cost are all partin the cost of wind. You would also need to replace wind generators twice as often, at least, as conventional plant.
      The best plant for efficiency, lower CO2 emissions and construction costs is the combined cylcle gas turbine

    • I A Reid
      I A Reid 22 दिन पहले

      @Túri Tamás

      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.

      @Túri Tamás, Of course I'm right, and of course it is no surprise that all these windmills are being built with low cost petroleum based energy. The only surprise to you is that your deception would be called out. As to Wartsila, all they have done so far is to announce an intent to design, and if they ever do design or produce any such battery driven drive trains for cargo ships those drive trains will be produced with petroleum based energy, and those batteries will be charged with petroleum fueled engines, just like all the other engines they have ever built anywhere in the world. The world CAN change, and when Henry Ford decided to design and build the world's first low cost V-8 automobile engine in 1931, he put up $625 million of his own money to do it with. He didn't try to bankrupt the entire world economy to prove his point!! And for a few years after that, more Ford automobiles were on the world's roads than all other brands combined.

    • Túri Tamás
      Túri Tamás 17 दिन पहले

      @Joe Brake You are right! There are exact calculations exist at SGRE, which shows all energy consumed from smelting raw material, until commissioning is being produced by the "avarage" windmill (it is around 3,5 MW) within three-six months of avarage operation. Lifetime is 25 years...the current infrastructure is petrol based (vehicles, shipping, jack ups etc.), this shall not be a surprise :) But just for your information, for example Wärtsilä is now started to manufacture 100% electric and battery driven drive trains for cargo ships....the world can change and it is good. The change is not only consume money (by the way, money is just money, countries are printing as much as the active industry actually needs), but it also creates tremendous amount of well paid jobs for the society as well. Sorry to say, but the numbers above are correct :)

    • Joe Brake
      Joe Brake 17 दिन पहले +1

      @Túri Tamás, sorry Turi, but these manufacturing and maintenance figures are bogus, and based on the low cost of manufacturing, transporting and installing these windmills using low cost petroleum energy to build the factories, to build the ships, to build the transport trucks and cranes, to manufacture and transport all the parts and the workers to their workplaces; all bogus. Try doing all this with battery powered equipment where the batteries are being charged by windmills. Then recalculate the cost, but only AFTER THE CHANGES have been accomplished. Sorry, but I had to laugh. Show me all your battery built and battery powered cargo ships and your battery powered parts delivery aircraft.

    • Túri Tamás
      Túri Tamás 22 दिन पहले

      sorry, but I had to laugh on that :D 3 MW direct drive turbines unit cost is 2,5 million EUR, and 5 million EUR service and operational, decommissioning cost for a 25 years span. It is very cheap, 625 EUR per household for 25 years of electricity...it is cheaper the any other energy source. Problem is that, wind can be only used in combination of other energy sources (but this is not really a problem in Europe, where countries can import/export electricity etc.)

      @. Wookey There is no reason not to build them from aluminium other than up front cost, aluminium is 100% recyclable. Fibreglass and resin is 100% pollution. They are building them for profit not the planet, it's a false economy and another con. If they're going to pretend to be clean then do it responsibly not just for profit. Your 90% recyclable claim is pure fantasy. I'd say you're lucky if it's 50% recyclable and it still uses fossil fuels to make them.

      @Dubsy Dubs Wind turbines are 90% recyclable, and very quick and easy to disassemble. That's pretty good for power station technology. Which technology do you think is better in this regard? It's also really cheap and (as I already said) really low-carbon. That's a pretty compelling set of pluses, which is why it's expanding hugely at the moment.

      Still only 10gCO2/kWh for wind turbines. 2-4 times better than solar, 40 times better than gas, and 80 times better than coal. When you have a lower-carbon idea we will be pleased to hear it. Onshore wind is the lowest-carbon technology on the planet, except some of the better hydro projects. Nuclear is nearly as good. Everything has it's issues, but windpower is pretty good, and of course because global warming _is_ real we'll be needing a great deal more of it.

They don’t have huge areas of nature dotted with ugly towers and the bird population is much happier in france. Germany got scammed into that wind crap because that stupid bitch.

      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.

    There are a lot of them offshore of England coast. They didnt say where. But allmost all are sinking. They drove steel casings down 160 feet.
    It took about 5 years they noticed the inner casing sinking, sliding down. They NEVER WELDED THE 2 STEEL CASINGS TOGETHER.. They cut holes in the inner casing and welded 2in × 10in bits in the holes. I think the outer case is sinking now. 3yrs later.
    They never drove the casing down to bedrock... How deep is bedrock off England coast?? Hope that engineer has good insurance....

      There have been a couple of offshore windfarms that had grouting failures about a decade ago. They got fixed. The north sea is indeed largely made of mud so almost nothing installed there is mounted on bedrock. The foundations work fine.

      Turbines get more cost effective the bigger they are, so biggest is best in both reliability of supply and cost terms for windpower. Offshore they can make em as big as they like without anyone complaining, so they are 8-10MW, with 12MW on the horizon. Onshore people grumble about massive machines so they are usually 1-2MW.

      In large part it's because of government permits. A lot of governments won't permit the largest ones on land because they're "ugly". Also because of lobbying from the fossil fuels industry.

    So all those turbine combined will generate approximately 2.5 -3 million dollars of revenue per year... not sure what they cost to build, but I’d bet they never make a profit. No wonder green energy will not take off any time soon in all but the most advanced countries where current energy prices are already exorbitant

    First sentence of voice-over, wrong. Not a promising start. The energy of the wind is (partly) turned into electricity + a bit of heat and noise. Perhaps I'd better watch the rest with the sound off.

    At least 3.000.000 each divided by 15 cents per kW. This thing should produce 20 GW (or 20.000 MW) of energy to justify the cost. I hope Greta mastered her arithmetics.

      With a 20 year life, it should be 1MW... but the reality is that fossil fuels cost 1-3c per kWh depending on the fuel and where in the world it's being run, the rest is distribution costs and markup. So wind is still more expensive, but its getting closer. The biggest issue is that they cannot create their rated energy even for a small fraction of their operational time.

    Such False crap. Every episode who works and does maintenance on these windmills all say there is way to much repairs to make it profitable. If you bought one and financed for 15yrs it would be junk by the time you paired for it.

      rafael Perez they have put those eye sores up and they’re not making any money on then they cost way to much and Maintain them is high. There Carbon foot print is greater than anything else. Environmentalists have there heads up there asses. Natural Gas power turbines is still the best for the environment and for the economy. And doesn’t kill hundreds of thousand of birds. But if you have no natural gas you can turn to this method but the new technologies out there coal still can be used with almost zero emissions.

      Wind turbines kill 300,000 birds a year in the US.

      Don't get your panties in a bunch about wind turbines killing birds.

      The average offshore wind turbine can meet the annual needs of 1500 households.

      @Petru-Alexandru Dragusin Yes you need common sense to find this out. In the US the tips of the blades travel at 400kmh killing millions of birds world wide.that is fact! The edge of the blades collect dirt from the air and begin to fail about 1 year in they are made of fiberglass the motors also need constant maintenance and the power has trouble supplying the grid just not cost effective prices of power become too high put a burden on people. Do your homework before you criticize were I come from they are taking them down.
