The UK has avoided the need for gas imports worth £1.7bn since the start of the Iran war, as a result of record electricity generation from wind and solar, reveals Carbon Brief analysis. The surge in wind and solar output is cutting the need for gas-fired generation, which has been nearly a third lower than last year and fell to record lows in both March and April 2026.

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 Work and Do-it-Yourselfers

By

Paul Gipe

Any wind turbine and tower that cannot be safely lowered to the ground for servicing should have a fall arresting system for ascending, descending, and working atop the tower, a sturdy work platform, and safe, clearly identifiable anchorage points for attaching your lanyard. No one should climb a tower of any type unless they’ve received training in tower safety. . .

Man Falls to Death from E66 in Germany

By

Paul Gipe

On October 16, 2003 a 25-year old technician fell inside a 100-meter tall Enercon E66 tower, struck his head, and died according to an account in a local German newspaper. The man, unnamed in the Prinzitger Zeitung article, was performing warranty service on a ladder when he fell.

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.

Beating a Dead Horse–More on Smith-Putnam’s 1,000 kW Rating

By

Since I posted my article on the revised rating of Smith-Putnam’s famed wind turbine of the 1940s, I’ve received several comments. (See When is a 1,250 kW Wind Turbine Only 1,000 kW? Setting the Smith-Putnam Record Straight.) One was from an old wind hand, Mark Haller. Others also noted the historical record is rife with the error.

I receive a fair amount of mail of the “What do you think of this” variety. Often it’s a quick push of the delete key and I am off about my business. Occasionally I’ve been known to go “Hmm” and forced to go a little further. A proposal by SAILWIND from the Hochschule für Technik, Wirtschaft und Gestaltung, Konstanz (the University of Applied Sciences, Constance) falls into the latter category.

When is a 1,250 kW Wind Turbine Only 1,000 kW? Setting the Smith-Putnam Record Straight

By

Paul Gipe

French colleague Philippe Bruyerre called my attention to an error I’ve been promulgating for at least four decades. He noted that I’d described the famed 1940’s era Smith-Putnam wind turbine as rated at 1,250 kW. It was not he wrote. It was really only a 1,000 kW wind turbine.
