In sum, around three-quarters of the technical potential for offshore wind involves floating offshore wind farms. Indeed, all offshore wind, both floating and fixed-bottom, could provide more than 2100 TWh of UK electricity (see HERE). This is much more than the UK will ever need to meet net-zero greenhouse gas policy objectives, or indeed any other policy objectives.
DAF-Indal[1] began working with Canada’s National Research Council and provincial utilities to develop Darrieus wind turbines using Canada’s abundant aluminum in the mid 1970s.[2]
They constructed about a dozen small prototype Darrieus turbines less than 5 meters in diameter and about 9 meters tall in the mid to late 1970s, rated variously from 4 kW to 12 kW.[3] One was installed in the Arctic for Canada’s Defence Research Establishment.[4] Another was installed in Texas at the USDA’s Bushland Experiment Station in a wind-assisted pumping test. Another was installed on Block Island, Rhode Island.[5] One was still standing—inoperative–outside Toronto in 2007.[6]

A worker has died after being crushed by a turbine blade at Australia’s biggest wind project, the Golden Plains wind farm in Victoria, with emergency services called to the site at Rokewood just after 8am on Monday.
Police confirmed the man was working at the wind farm on Bells Road when he was crushed beneath a “fan blade” shortly after 8am. First responders attempted to revive the man, but he was declared dead at the scene.
Offshore wind is currently broken. There is a despondent mood in the sector, and it looks like everybody is trying to get rid of their assets or reduce their exposure to the sector (see BP, Equinor, Shell, Vattenfall, Total, an even Ørsted, Corio or Bluefloat). And yet – they brought this on themselves, through a combination of hubris, ignorance, and reliance on lobbying rather than good business acumen.
Accidents involving wind turbines and airplanes are few and far between, according to the National Transportation Safety Board’s online database.
The crash of a small Piper aircraft destroyed in an April 27 accident when it crossed paths with the blade of a wind turbine near Highmore is only the second of its kind reported in the database. Last month’s accident is under investigation by the NTSB, a federal group that investigates all aircraft incidents.
The supervisor of an onshore wind farm construction site in Changhua County has been released on bail of NT$200,000 (US$6,260) following the death of a worker on Monday due to a CO2 leak incident, according to the Changhua District Prosecutors Office. The incident occurred on Aug. 20 at the Hai Long construction site for an offshore wind farm, resulting in one death, with two workers still in critical condition, and 14 others injured.
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.
