An entire fleet of around 100 'urban' wind turbines has been remotely shut down by manufacturer Quiet Revolution after the discovery of a design fault. The fleet of QR5 turbines was disabled after continual wind speeds of between 14 and 24 metres per second caused a turbine located on a sea wall in Blackpool to develop a mechanical error, the company said in a statement on Friday. The QR5s have been installed on 55 sites for clients including Network Rail, Sainsbury's and self-storage firm Big Yellow.

The Federal Aviation Administration says five wind turbines can't be built at the Massachusetts Military Reservation on Cape Cod, six days after approving them. The FAA now says the 400-foot high turbines pose a hazard to air navigation.

In addition to local residents, emergency first responders are considering how the proposal to site 70 wind turbines in Champaign County will impact them. The Federal Aviation Administration has issued notices of presumed hazard to navigable airspace for 38 of the proposed sites, noting their potential negative impact on Grimes Field, where a CareFlight hangar is located, and the privately-owned Weller Airport, which was used for a helicopter landing and takeoff to transport a crash victim on Oct. 6.

A transformer at the Maple Ridge Wind Farm's substation off Rector Road was destroyed by fire late Monday afternoon. Martinsburg firefighters were dispatched to the substation about 5 p.m. but had to wait until the facility was shut down before extinguishing the blaze, said Lewis County Fire Coordinator James M. Martin. ...The Columbus Day fire was the second transformer fire at the site, with a similar incident occurring July 4, 2007. In that case, 491 gallons of mineral oil leaked from the damaged transformer

Wind measurement towers put up ahead of planned wind farm projects are drawing concerns from crop dusters who say they blend in with the landscape. Crop duster Brian Hauschild says the main problem with the towers is they have no markings. Flying 140 mph at low altitudes in a small airplane carries numerous dangers, but the unmarked towers add a danger. ..."In the short-term, we're working on getting them marked so we can see them," he said. "In the long-term, I'm talking to the FAA, but this isn't something that will happen quickly."

Suzlon Energy Ltd (SUZL.BO) said on Monday it had finished a program to retrofit wind power turbine blades that suffered cracking problems, an issue that has weighed on the Indian wind turbine maker's shares. Suzlon, the No. 5 wind turbine maker globally, launched the $100 million effort last year after some blades on its 2.1 megawatt turbine fleet developed cracks. One blade broke off a turbine in Illinois.

Manufacturers of the 190ft high turbine, one of three owned by Sheffield University, are now investigating the damage at the site close to the city's Parkway link road to the M1. A blade on the same turbine was broken 15 months ago and residents who live close to the site at Catcliffe, near Rotherham, have expressed fears that they could pose a danger to local people.

A wind turbine at a school in Flackwell Heath has been repaired after part of it fell off into the school playground. A panel - about the size of a dustbin cover - fell off the back of the turbine at Carrington Junior School and the whole structure had to be taken down and repaired over the summer. ...Photographs and an anonymous letter were recieved by the Bucks Free Press saying: "If this can happen, the turbine is a danger and should not be installed anywhere near our children."

During an evidentiary hearing Wednesday, Fayette County Judge Steve Leskinen heard arguments concerning eight proposed wind turbines the county's zoning hearing board rejected in June, including concerns about public safety. The towers, which are owned by Oregon-based Iberdrola Renewables, formerly known as PPM Atlantic Renewables are 262.5 feet tall and 12.5 feet higher than allowed under the zoning ordinance.

The first major UK hydro project to be completed in 50 years, Glendoe was closed less than two months after the Queen officially opened the 100-megawatt station at the end of June. Yesterday, Perth-based SSE said investigations showed that the rock fall, in a tunnel carrying water between the reservoir and the power station, was "very substantial". ...SSE also confirmed the Greater Gabbard wind farm in the Thames Estuary had been hit after faulty welding was discovered on the turbines.

The Federal Aviation Administration recently informed Buckeye Wind, LLC. that its study found 38 of the 70 proposed turbine building sites in Champaign County exceed obstruction standards and could be a hazard to air navigation near Grimes Field. FAA guidelines generally restrict objects taller than 200 feet within five nautical miles, approximately 5.75 standard miles, of an airport that size.

The German army has identified a series of wind park projects as a threat to national security and blocked investments worth 1.5 billion euros because it fears spinning wind turbines will interfere with its radar systems. The Bundeswehr has launched an investigation into the impact of the wind turbines planned for northern Germany's coastal area amid concerns they could compromise air defense -- because they could in theory provide a shield for enemy aircraft.

An injured worker from the wind farms off Clacton has been taken to hospital after falling through a hatch on a tug boat. The 24-year-old German man was hurt while working aboard the vessel Arion which transports equipment out to the wind farms.

Work will get under way this week to repair a wind turbine damaged by a fire last month at the Kent Hills wind farm in Albert County, roughly 30 km southwest of Moncton. One of the 32 wind turbines at the site caught fire on the morning of Aug. 8, and it's been offline since.

State police closed a portion of Route 3, from Bolton Road to Benton Road, for about three hours Wednesday after the base of a wind turbine and the trailer it was attached to became unlatched from the rig hauling the oversized load. Both the trailer and turbine overturned and rolled into a nearby cornfield, state police said.

A man has died in an accident while carrying out maintenance at a wind farm today. It is understood the man was working high up on one of the turbines but did not fall. Police were called at around 9.15am to the Causeymire Wind Farm, south of Spittal, near the A9 in Caithness.

With their organic gardens and ample land, Andy and Jessie Welsh had the perfect plan. Living in rural Stearns County, the young couple had hoped to be energy self-sufficient and green. ...From the start, the installation was delayed and marked by setbacks. Electricians had a hard time getting the turbine wired to run properly. When it finally did, the turbine ran for just a few days before they received a call from the company instructing them to shut it down.

Coca-Cola has scrapped plans for a towering wind turbine at their Wakefield site - after police raised fears it was too near the force helicopter's landing pad. The soft drinks giant wanted to build a 110-metre high turbine in a bid to make its bottling and distribution centre on the Wakefield 41Industrial Estate cleaner and greener.

TransAlta Corp. is still investigating what caused a fire last month that destroyed one of its turbines at the Kent Hills Wind Farm, a company spokesman says. ...Lightning has been ruled out as a factor in the Aug. 8 fire.
