Workers are inspecting and repairing 75 wind turbine blades at a wind farm some 60 miles east of San Diego after a storm a month ago caused catastrophic damage to some of them. ..."The turbines were actually stopped," he said. "There were extremely high winds on the site - that contributed to the blade cracking."

A faulty sensor on a giant wind turbine is being blamed for huge shards of ice flying off its blades and crashing into nearby homes and gardens. As The Evening Telegraph reported in November, residents in King's Dyke, Whittlesey, had to take cover for more than four hours when huge lumps of ice, some measuring 2ft, were flung from the giant machine's blades.

PITTSBURGH Wind power may be flying high, but the young industry fears its growth may be clipped if federal rulemakers and Congress continue to set up new regulatory hurdles.....in January, Congress mandated a study of the effects of proposed wind turbines on military operations, including aircraft radar, triggering special scrutiny by the Federal Aviation Administration and the Department of Defense .

Rob Pforzheimer, a Sutton resident and longtime First Wind critic, said, "This is the second haz mat spill [TNT truck in December] on this project and it hasn't even started producing anything yet. There will undoubtedly be more spills in the future.

Controversial plans to build a wind farm near Aberford have been blown away by councillors. The city council's east plans panel has turned down a developer's proposal to put five 125m-tall wind turbines in the green belt on Hook Moor just north of Micklefield. A council report said the application was refused because it would adversely impact on the Precision Approach Radar at RAF Church Fenton and impact upon the Primary Surveillance Radar at RAF Linton on Ouse.

The wreck blocked U.S. Highway 52 and cut off access to the bridge from U.S. Highway 20 for more than two hours. It was cleared by late morning.

A failure in one of the wind turbines owned by the Iberdrola company in the Pedregal Mountains, Esteiro (Muros), resulted in a forest fire that razed a hectare of the mountain.

Wind turbine maker Siemens Power Generation will try to convince Oregon regulators today that adequate safety measures were in place when a 230-foot tower collapsed and crashed to the ground in a Sherman County wheat field last summer. Technician Chadd Mitchell, who was working high in the nacelle, the structure that houses the turbine's generating components, died in the Aug. 25 incident at the Klondike III wind farm. Another technician, William Trossen, was injured. A third employee, Dustin Ervin, sitting in a truck nearby, gunned the engine to avoid the falling wreckage and escaped unharmed, according to a state report. ...Siemens hasn't refuted the sequence of events that led to the collapse, but it objects to the division's findings of safety violations. "The employees demonstrated they could do the work they were trained to do safely," Siemens spokeswoman Melanie Forbrick said. "The actions that led to the incident were not actions that were related to the work they were performing." Siemens appealed the findings March 21.

State senators pressed the developers of a North Shore wind farm on Tuesday about the safety of their technology in light of a major fire that destroyed their battery storage facility and sent toxic fumes into the air. ...The wind farm also experienced two previous fires that destroyed inverters after coming online in 2011.

The Federal Aviation Administration, with backing from the Air Force, issued a "notice of presumed hazard" in March, barring construction of any towers above "0 feet." The company hasn't been able to resolve the issue, even with Oregon Sens. Ron Wyden and Jeff Merkley trying to run interference. "We're just sitting here in no man's land," said Les Gelber, a Caithness Energy partner.

Military officials warned this week that building the proposed Pantego Wind project in eastern North Carolina would create an unavoidable collision hazard for fighter jets, a development that would force Seymour Johnson Air Force Base to deploy flight training to other states.

Seymour Johnson Air Force Base, located in Goldsboro, N.C., has released its analysis on the impact of nearby wind energy projects to its low-altitude flight training programs. The result of that analysis was that turbines would create hazards to the training missions.

The U.S. Air Force Space Command said it has checked and rechecked and still believes a proposed wind farm on Nantucket Sound would not affect its PAVE PAWS radar station in Sagamore. “Everything that the Air Force Space Command is saying indicates that [the turbines] would not be tall enough to interfere with operations,” said Lt. Col. Christopher Gentry, commander of the Air Force 6th Space Warning Squadron, Cape Cod Air Force Station, the group responsible for running the radar facility. But wind farm opponents, specifically the Alliance to Protect Nantucket Sound, point to a larger study now being undertaken by the Department of Defense, one that won’t be available until spring. That study, says the Alliance, will be more comprehensive and was itself prompted by issues with the Air Force’s initial analysis. “Until we have a written report in hand that we can review to understand the parameters of the study, it would be inappropriate to offer comment,” said Charles Vinick, president and CEO of the Alliance. “It is my understanding that there is a larger study under way and it would be premature to offer conjecture on what that might find.”

A Chugach Electric idea to put giant, electricity-producing windmills on Fire Island is giving its neighbor, Ted Stevens Anchorage International Airport, a case of bad vibes. Radar experts recently found that electromagnetic waves from the proposed 33-windmill project would be so strong they would warp the signal of the airport's main air traffic control radar. On top of that, the sheer size of the windmills, whose blade tips could reach 400 feet in the air, would also physically block the signal of another key radar already on Fire Island.

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.

Airport board chairman Charlie Tatham says the board had been under the impression the turbines were sited south of Hwy. 91, and was surprised to find at least one turbine proposed for a location within two kilometres of the main runway. The turbine poles are about 500 feet tall.

For the first time in more than a year, a group other than the Solano County Planning Commission will be discussing a proposal to install up to 88 wind turbines in the Montezuma Hills. The Solano County Airport Land Use Commission will hear the issue Thursday night, a year after voting against the issue the first time around for fear of the turbines affecting the radar system at Travis Air Force Base. The difference this time is that officials at Travis are no longer objecting to the proposal, as stated in a letter written by Wing Commander Col. Steven Arquiette earlier this month. ...The company proposing the project, enXco, has offered Travis a gift of up to $1 million that the base may use anyway it wishes.

Fears are being raised that proposals to put wind turbines on the roof of the Civic Centre could interfere with radar at Exeter Airport.

According to chiefs at Cambridge Airport, wind farms can interfere with radar across a distance of up to 40 miles. The two feasible locations for the aerospace giant’s move away from Cambridge are Wyton and Mildenhall but wind farms are planned in the vicinity of both. David Buckley, airport director, highlighted the issue at the latest meeting of the Cambridge City Airport Consultative Committee.

HOLLAND -- Airport officials don't want modern, sky-high versions of windmills near the Tulip City Airport.
