Suggestions to reform the German electricity market

Overall, we believe that this handful of relatively straightforward measures could materially enhance the transition towards a low-carbon Electricity System at low cost. The Energiewende gets a bad rap in the English-language press, even though it has helped create a competitive renewable energy industry from scratch – something the whole world benefits from, even though mostly German ratepayers pay for it. Our proposed reforms would help reduce that last item.

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.

History of Wind Power

Utrc Pendulum Composite Bearingless Rotor

Failed Dream: the Bearingless Wind Turbine Rotor of the Late 1970s

By

Paul Gipe

On paper the composite bearingless rotor seemed too good to be true: a wind turbine rotor that enabled the blades to change pitch without bearings in the hub. And the wind turbine would passively use aerodynamic forces to orient the rotor downwind of the tower. It was the height of simplicity and would be cheap to build. What could go wrong? The short answer: everything. Eventually the nearly 400 wind turbines using the concept in California during the Great California Wind Rush of the early to mid 1980s were scraped off the face of the earth for scrap. And therein lays a sprawling tale.

NREL’s Wild West of Wind: a Glimpse of California’s Past

By

Paul Gipe

While interviewing Brian Smith about his early career during the Great California Wind Rush, he mentioned that NREL had done a retrospective on the history of the lab. Specifically, he suggested I take a look at the chapter titled the Wild West of Wind. Yee ha! Brian was right. He and Walt Musial have some great tales in that chapter. If you weren’t working in California’s wind industry then and you want a flavor of what it was like, take a look. The title is a pretty accurate summary of the times.

A Windmill Near Brighton By John Constable

Learning to love monsters: Windmills were once just machines on the land but now seem delightfully bucolic. Could wind turbines win us over too?

By

External Source

Yet perceptions of windmills have not been uniformly idyllic. Since they first appeared on the landscape of medieval Europe, windmills represented an imposition of the technological on the pastoral. They were, in the phrase of the wind energy author Paul Gipe, ‘machines in the garden’, straddling the boundary of the agrarian and mechanical.

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.

When James Blyth created what many believe was the world’s first wind turbine in 1887, villagers dismissed it as the “work of the devil”. The huge structure at Blyth’s family home in the Aberdeenshire village of Marykirk was built with four cloth sails and generated enough power to light 10 bulbs along with a small lathe. It is said that he offered to light the streets of the village with his electricity but the offer was shunned. Blyth’s vision of a future powered by wind only started to be realised many decades after his death
