Dismantling a wind farm: all the details of a real case

The dismantling of the Muel wind farm demonstrates that circularity in wind energy is already an industrial reality. The results, with an outstanding 99.85% of materials recovered or recycled, confirm that recycling or recovering nearly 100% of a turbine is not science fiction, but the outcome of applying engineering, collaboration, and technical knowledge. The next step for the industry will be to make it faster, more cost-effective, and with greater added value in each material flow, consolidating circular economy as a standard practice in future repowering projects.

Europe should seek constructive cooperation with China on energy policy. Even though the two regions are developing very differently in socio-political terms, cooperation in the field of energy and climate policy offers enormous opportunities for the whole world. Europe and China can play a key role in the global energy transformation and in the global fight against climate change by using their resources for this purpose. This naturally requires constructive dialogue on an equal footing, in which both blocs formulate their own and shared interests and develop their relations on a clear basis. This also means that Europe and China can and should work together to convince numerous other countries that the path of renewable energies is the path to a good future for all people, a prosperous and more peaceful world that successfully overcomes the climate crisis.

Accidents & Safety

I’ve been concerned about safely working with wind energy since 1976 when I nearly killed myself taking down a 1930s-era windcharger. While wind energy is an environmentally beneficial technology–and that’s the reason we need to use it–it can and has killed. Consequently, I’ve been tracking fatal accidents in wind energy since I wrote an obituary for a colleague, Terry Mehrkam, in 1981. For this reason, my books on wind energy have always included a section on safety.

By

Paul Gipe

Presentation to Winterwind 2021 21 April on a Comparison of Wind’s Fatalities to that of Other Industries. Wind energy’s hazards, like its appearance on the landscape, are readily apparent. Wind energy hides no latent killers, no black lung, for example. When wind kills, it does so directly and with gruesome effect.

Tower Climbing Safety

Safety

In 2013 I pulled together some links to documents on safety relative to the wind industry. These topics went beyond simply tower climbing safety and safety at height and included work around rotating machinery and other common industrial hazards. Unfortunately, the industry has changed dramatically in the past decade. Most safety documents once freely available are now securely hidden by paywalls. Moreover, even the wind energy trade associations where these documents were once located have ceased to exist, merging with other renewable trade associations. Some of the British documents are still available and I’ve provide links to them. I found one public document on the off shore industry in the USA.

Museums with Wind Exhibits

Museums often have extensive permanent collections and only display a small portion at any one time. Museums frequently change their exhibits and that is the case below. The museums noted here have all changed their exhibits since I last visited. Some have created “virtual” exhibits, and these I’ve noted.

North American Open-Air Museums

European Open-Air Museums

There’s nothing like walking among the operating windmills of Zaanse Schaans in the Zaan district of Noord Holland, or strolling among the vertically-jutting blade sculpture at the Folkecenter for Renewable Energy in Denmark to gain a sense of the importance of wind in European–and thus Western–culture. For the avid wind aficionado and the scholar alike, I strongly suggest putting one of the many open-air museums in Europe on your travel itinerary. Some we discovered by serendipity others we searched out. All were worth the effort.

Note that in most western European countries there are national “windmill” days where many of the historical windmills are open to the public. Many now include some modern wind turbines as well. Often the national windmill day is the second Saturday in May though this may vary by country. In Germany, Deutscher Mühlentag is held on Whit Monday or Pfingstmontag in German. In 2023 Whit Monday was 29 May.

  • Museum Park, Deutsches Technikmuseum Berlin, Germany displays a historic stage mill, a mechanical farm windmill, and a micro wind turbine.
  • Schloss Sanssouci Berlin displays a reconstructed stage or gallery windmill that has served the palace (Schloss) since 1787. It was a mill on this site that served in the famous legend of the Miller of Sanssouci who challenged kingly power.
  • Windmill Blade Expo at the Folkecenter for Renewable Energy in Jutland, Denmark.
  • Showroom for historical Danish wind turbines at the Folkecenter for Renewable Energy in Jutland, Denmark–An extensive collection of wind turbine drive trains from the early days of Danish wind power.
  • Poul la Cour Museum–The museum is situated in the historical buildings where Poul la Cour, affectionately called the Danish Edison by Danes, conducted his research into wind energy and hydrogen storage. The site is the cradle of modern wind energy.
  • Energimuseet Vindkraft–The museums’ open-air exhibits include the original nacelle from the famed Gedser mill designed by Johannes Juul, an erect Riisager machine from the rebirth of Danish wind energy in the late 1970s-early 1980s, a cut-away wind turbine blade and more.
  • Frilandsmuseet–The Open Air Museum north of Copenhagen is one of the largest and oldest in the world. Spread across 86 acres of land the museum houses more than 50 farms, mills and houses from the period 1650-1950.
  • Museummolen Schermerhorn–Open air museum of the polder mill on the Schermer polder in Noord Holland (north of Amsterdam).
  • Germania (molen)–Platform grain grinding mill in the province of Groningen, the Netherlands. One of the more than 1,000 windmills in the Netherlands that are periodically open to the public.
  • Internationales Muhlenmuseum–in Gifhorn, Niedersachsen, Germany has 13 different windmills on display, including a Greek sail windmill.
  • World Heritage Site of Kinderdijk–The nineteen windmills of Kinderdijk illustrate the way the Dutch have used windmills to drain the polders that have made the Netherlands what it is today. Kinderdijk is most likely the world’s oldest wind farm and was in use into the 1950s.
  • De Vereniging Zaanse Molen–No tourist trip to the Netherlands is complete without a visit to Zaanse Schans and the working windmills of the Zaan district. The Society of Zaan Mills was founded in 1925, beginning with the restoration of the oil mill De Zoeker. Three years later, they opened the Mill Museum at Zaanse Schans. Now, nearly a century later, the Society possesses 12 industrial windmills, representing an important part of Dutch cultural heritage and to this day still define the Zaan skyline.

More on Fayette Manufacturing and its One-Time Resurrection

By

Paul Gipe

While archiving articles I’d written for the American Wind Energy Association’s newsletter, Wind Energy Weekly, I came across this one about Fayette’s restructuring in 1990. At the time I was the west coast representative for AWEA in Tehachapi. There’s not a lot on my web site about Fayette. (I do mention them in my books and in articles on capacity factor and how this figure of merit can be so misleading.) Consequently, for historical reference I am posting the article with the original date that I submitted it to AWEA. See Fayette Reborn in Major Restructuring.
