Noble Environmental Power officials say they have detected a "wiring anomaly" in two Altona wind turbines, including the one that snapped in half last Friday. As the preliminary investigation continues into how a massive turbine suddenly collapsed, Noble officials said this week that the entire wind park experienced a loss of power Friday and that two of its 65 turbines apparently malfunctioned.

U.S. Forest Service officials had a tour scheduled Wednesday afternoon to show off to journalists a pair of recently installed wind turbines. But they had to cancel the tour when 100 mph winds damaged one of the turbines Tuesday night. "We were kind of tickled" by the irony, acknowledged Maribeth Pecotte, a spokeswoman in the Forest Service's Boulder Ranger District office. ...The turbine project is costing the Forest Service $171,568 over a 15-year financing contract, Pecotte said.

Three wind turbines at Perkins High School crashed Saturday when the blades broke off one of them. No one was hurt when parts of the fiberglass blades came off the turbine as it spun, winging the blades up to 40 yards away from the silver monopole tower, near the high school at 3714 Campbell St. The remaining two turbines will not be used until they are inspected and officials figure out what caused the blades to break.

A runaway windmill in Tehachapi closed Highway 58 -- a major east-west freeway connecting California's southern Central Valley to Las Vegas, Nevada and Arizona -- for most of the day Sunday. As of 6:45 p.m., the highway remained closed between Tehachapi and Mojave. Officials had no estimate as to when it might reopen

Frontier Pro Services of Banning, California conducted an informal survey of approximately 75 wind farm operators in the United States. Designed to assess the specific operation and maintenance service needs of wind energy operators, the survey reveals potentially serious threats to wind farms owing largely to the industry-wide shortage of qualified turbine technicians.

When it came time to start repairing a wind turbine at the ethanol plant on Oct. 15, the project had to be put on hold. ..."The blade has been cracked all summer. It's been frustrating," says Dan Moore, director of project development for Renewable Energy Solutions. When the broken blade was discovered, the turbine furthest from the ethanol plant had to be shut down. All three blades needed to be replaced, says Moore, because we couldn't find one to match the other two.

Ecotricity, which owns the site, are continuing investigations and have said they are not ruling anything out - though the extent of damage was "unique". To make one of these blades fall off, or to bend it, takes a lot Dale Vince, Ecotricity.

The construction company, ICS of North Dakota, lifted the wind turbine rotor assembly, to which the blades attach, 246 feet high into place late yesterday afternoon. After it was lifted it was discovered the blades were not ‘feathered' or turned properly so they could not catch the wind. In the position the blades are in, the wind caught the blades causing them to spin. When this was discovered, the Bremer county sheriff's department was notified and all personnel were evacuated, including two homeowners who were outside of the recommended danger zone.

What we can't see from Kingston, but what one island neighbour told me is among the biggest changes to their lives, is the noise. When the wind is up, "it sounds like a jet engine coming through -- and they're not all up and running yet."

It all came down to glue. And how it was misapplied by workers. Spanish wind-energy company Gamesa said "insufficient and irregular distribution of glue" caused large pieces to break off seven turbine blades at the Allegheny Ridge Wind Farm near Lilly, Cambria County. No one was injured during the mishap in mid-March, but pieces of the blades flew more than 500 feet, according to residents.

A 63-metre tall wind turbine bent in two at Beinn an Tuirc Windfarm last Thursday. In what has been described as ‘a catastrophic failure’ of the turbine, the tower section has folded in the middle smashing the blades and nacelle into the hillside. It is thought by those in the industry that this is the first time a turbine tower has ever collapsed in the UK and Vestas Celtic, which manufactures towers at its nearby Kintyre factory and Scottish Power owners of the farm have launched an inquiry to find out what went wrong with the Vestas V47 turbine.

"Most windfarms are near roads, railways, or walking paths, and the dangers are obvious."

A wind turbine blade came crashing to the ground Wednesday, halting energy production at a small-scale wind farm southwest of Wyanet because of what may be a defective design. In all, four turbines on Richard Shertz's property - all part of the AgriWind facility in central Bureau County - have stopped turning after a blade on top of one of the towers broke off about 9:30 a.m. "It was the loudest noise I've ever heard," he said. "I thought it was thunder."

Damaged rotor blades and forex losses caused the world's fifth-largest wind turbine maker Suzlon Energy post a consolidated net loss of Rs 34.90 crore for the quarter ended December 2008 against a Rs 142.8 crore profit in the corresponding previous quarter. ...Cracks were detected in 170 of the 1,250 blades for 400 turbines of the S88 V2 model supplied by Suzlon in 2007 to two of its major clients in the US -- Edison International and John Deere.

Shortly after 9 a.m. Wednesday, a rotating blade on a wind turbine at Schertz's farm broke off, plunging to the earth in a cornfield about 150 feet west of the turbine. ...The spokesperson said the investigation into this turbine had just started, but the company was in the middle of a blade retrofit program across the United States to correct an "unfortunate" design issue in the first generation of this blade.

One of the three 60-foot-tall wind turbines at the edge of the Perkins High School student parking lot lays on the ground. The pole was removed from the 4-foot deep, 60-ton concrete base. ..."We have no updates," he said. "The manufacturer is finalizing the investigation as to the malfunction of the blades."
