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.

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.

Films and Videos of Historic Wind Turbines from 1925 to the Present

By

Paul Gipe

I’ve uploaded a series of films on historic wind turbines in operation to the Internet Archive. To help me keep track of them, I’ve posted the links and a short summary here. I’ve included some films in this list that are on YouTube.com as the provenance isn’t clear. Of course videos of operating wind turbines are quite common now, so I am limiting this list to those of historic interest.

The annals of wind energy are filled with examples of arrogance, hubris, and hype about products that failed to deliver on their promoter’s promise. One long forgotten example is the Schachle wind turbine. However, unlike the Internet wonders that bedevil us today, the Schachle wind turbine was a real piece of hardware not merely electrons floating in the ether.

Lassoing a Runaway Windmill

By

Paul Gipe

It was common knowledge on California wind farms in the 1980s that one way to stop the rotor from spinning out of control was to somehow get a rope tangled in the rotor. The rotor would then wind up the rope, wrapping it tightly around the main shaft, slowing the rotor if not stopping it. To get the rope into the rotor, it was necessary to shoot an arrow towards the rotor with a line attached. If successful, the spinning rotor would do the rest.

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.
