A cold front swept across northern China's Inner Mongolia region in early November, forcing a wind energy farm at Xilin Gol to curtail operations - even as a brisk breeze whistled through idle turbine blades. "When that much wind is moving through, the generators can't make electricity," explained Ma Zhanxiang, vice president of the Inner Mongolia Electric Power Industry Association (EPIA). "Money just blows by." ...Inner Mongolia's situation is a clear example. Its installed capacity - 50 gigawatts -- is the country's largest, but the excess at wind farms has reached a crisis level. EPIA counts some 10 gigawatts in the region, including 3.49 gigawatts of wind power, as excess installed capacity.

It was another restless night in a long string of interrupted sleep. Amaranth's Leo Mendonca didn't feel quite right, like something was wrong, but he didn't know what, or why. When he got out of bed, he was struck by a wave of nausea. ...Thinking some fresh air may do the trick, he headed out to the garden. There, he looked up and saw what he now believes is the source of his troubles ... an industrial-sized wind turbine about 600 metres away, and many more within sight.

A majority of Narragansett residents support wind turbines in their community, according to a survey released last week by the R.I. Department of Environmental Management and town of Narragansett. ...Seventy-one percent supported wind turbines if they could not hear them from their house. However, support dropped to 38 percent if they could be heard from their house.

An engineering lecturer given the task of monitoring noise levels around the Waubra Wind Farm says there needs to be a thorough independent investigation by the State Government. University of Ballarat engineering lecturer Graeme Hood has spent time at Waubra monitoring sound levels in the area to determine the nature of sound emitted by the wind farm. Mr. Hood commenced the research in September in response to complaints from a number of residents.

News that $450 million in federal stimulus money might go toward installing Chinese-made wind turbines in Texas prompted criticism on Thursday, with Senator Charles E. Schumer, Democrat of New York, calling on the Obama administration to deny federal financing. According to partners in the deal, the proposed 600-megawatt wind farm, announced late last week, would be built on 36,000 acres in West Texas using 240 wind turbines manufactured by A-Power Energy Generation Systems of Shenyang, China.

The total cost of the project, which was brokered in part by the U.S. Renewable Energy Group, an American private equity company, was estimated at $1.5 billion. ...The group's calculations last week put the number of American jobs at a little more than 300 - most of them temporary construction jobs, along with about 30 permanent positions once the wind farm is operating. Mr. McGarr told The Wall Street Journal that more than 2,000 Chinese jobs would be created by the deal. That, along with the fact that the project was hoping to secure 30 percent, or $450 million, of its financing from U.S. stimulus funds, was enough to send tempers flaring.

University of Ballarat engineering lecturer Graeme Hood said the Victorian Government should commission a comprehensive independent investigation to determine exact levels of inaudible sound produced, after his own study proved inconclusive. ...Mr Hood said his research found that an audible swishing noise emitted by the turbines ranged between 60dB, or the equivalent of conversational speech, and 80dB, or the equivalent of average street traffic.

A Sino-US consortium yesterday announced plans for a US$1.5 billion, 600MW wind farm in Texas, with China supplying all the turbines and most of the funding. The 36,000-acre wind farm ...is a joint venture between state-backed Chinese firm Shenyang Power Group, US wind farm developer Cielo Wind Power and private equity firm US Renewable Energy Group. Most of the funding for the project will come from Chinese banks, with loan guarantees and grants provided by the US federal government's economic stimulus package.

Ontario's Medical Officer of Health Arlene King doesn't see any scientific evidence that links wind turbines with adverse health effects. When contacted yesterday, Ministry of Health and Long- Term Care spokesperson David Jensen said it is King's position that there is no link between the noise turbines make and adverse health effects people claim to be experiencing, such as severe headaches and joint and muscle aches.

Two speakers said wind towers need to be a safe distance from homes and another said they do not need to be in Vermont during a forum Thursday. Vermonters for a Clean Environment organized the meeting at West Rutland Town Hall in light of the proposal of Vermont Community Wind Farm to build an 80-megawatt development in and around Ira. VCE executive director Annette Smith moderated the meeting.

"The Green Energy Act, 2009 and its regulations clearly do not appear to meet the requirements of law in the province of Ontario," said lawyer Eric Gillespie today in a news conference at Queen's Park. On behalf of his client Ian Hanna, Gillespie explained that a court application was filed earlier today for judicial review of the Green Energy Act, 2009 based on the Precautionary Principle as it applies to industrial wind turbine installations.

The Victorian Government will examine claims that Waubra's 128-turbine wind farm is harming the health of nearby residents. Finance, WorkCover and Transport Accident Commission Minister, Tim Holding, wrote to Western Victoria MLC Peter Kavanagh earlier this week to confirm that three government departments would examine "potential hazards" caused by sub-audible noise emitted by the turbines.

The State Government will investigate the health concerns of Victorians who live near wind farms. Last month, the Democratic Labor Party Member for Western Victorian, Peter Kavanagh, asked the Government to investigate whether workers near wind farms faced health hazards. Some landholders near the Waubra wind farm, west of Ballarat, say a low frequency hum from the turbines is making them sick.

The State Government will investigate what health effects the wind farms in Waubra, near Ballarat, will have on locals. Western Victoria Democratic Labor Party MP Peter Kavanagh said residents were concerned about the effects of sub-audible noise produced by wind farm generators.

Bell Acres Council will soon decide whether one more footprint will disturb the great blue herons and other residents. An alternative-energy demonstration site - involving a single 66-foot-high wind turbine, a 15-foot-high turbine, some solar panels and a trailer - has been proposed by a collaboration of Metal Foundations (Ambridge), Vox Energy (Allison Park) and Jet Industries (Ellwood City) for a site near the intersection of Big Sewickley Creek Road, also designated as the Red Belt, and Turkeyfoot Road.

The fact wind farm noise can be heard by neighbours does not necessarily make that noise unacceptable or significant, a hearing has been told. ...The company wants to build 56 more turbines on the eastern side of the Tararua Ranges, but is running into opposition from neighbours annoyed about noise.

Today, the WHO Regional Office for Europe launches its Night noise guidelines for Europe. (1) The book provides ground-breaking evidence on how exposure to night noise can damage people's health, and recommends guideline levels to protect health. The new limit is an annual average night exposure not exceeding 40 decibels (dB), corresponding to the sound from a quiet street in a residential area. Sleepers that are exposed to higher levels over the year can suffer mild health effects, such as sleep disturbance and insomnia. Long-term average exposure to levels above 55 dB, similar to the noise from a busy street, can trigger elevated blood pressure and heart attacks. One in five Europeans is regularly exposed to such noise levels.

Turbine noise will likely be the most contentious issue at a hearing to decide if an extension to Te Rere Hau wind farm should be allowed. Thirty-three of 36 neighbours of the proposed wind farm, east of Palmerston North, oppose an extension because of noise concerns. New Zealand Windfarms yesterday defended its record on turbine noise as it sought the right to add 56 turbines on the eastern side of the Tararua Ranges. ...Despite a series of complaints about noise, the company argued it could show it was complying with consent conditions.

Results from testing at Waubra windfarm have led Ballarat University lecturer, Graeme Wood, to consider undertaking further investigation to understand what effects the turbines are having. "There are grounds for investigation," he said. ...Speaking last Friday, he said that noise levels are not extreme, but there is a much broader band present than originally expected. "There is more noise at low frequency than expected. The turbines make a range of sound," he said. Also of interest are high pulses of sound, several times a second.

Leventhall's views on Pierpont's research are clear, he is certain that noise can be an issue for some people living close to wind farms and the symptoms that the paediatrician describes are very real. "The wind developers are going to rubbish her book, and quite rightly so, but what must be accepted - and developers don't want to accept this - is that yes, people are disturbed," he says. "If people are consistently disturbed, and their sleep is consistently disturbed, then they will develop some very ‘unclever' stress symptoms. That will lead to stress-related illness."
