Wind power gets clean bill of health

Tur­bines do not make peo­ple sick, industry-funded study of impacts concludes

By Tyler Hamil­ton – Toronto Star

The most thor­ough study to date into the poten­tial health effects of liv­ing near wind tur­bines says the evi­dence so far is clear: they don’t directly make peo­ple sick.

But the inde­pen­dent expert panel that pre­pared the wind-industry study, to be released today, con­ceded that some peo­ple can get stressed out by the “swish­ing” sound wind tur­bines often make.

A small minor­ity of those exposed report annoy­ance and stress asso­ci­ated with noise per­cep­tion,” the panel con­cluded, point­ing to sim­i­lar annoy­ances that can come from high­way or city traf­fic, local indus­try and air­planes. “Annoy­ance is not a disease.”

New Ontario rules require all wind tur­bines to be set back at least 550 metres from the near­est res­i­dence to assure noise lev­els do not exceed 40 deci­bels. That’s less than the noise that comes from light car traf­fic on a res­i­den­tial street, but some say it’s not enough.

The 85-page study, com­mis­sioned by the Cana­dian Wind Energy Asso­ci­a­tion and Amer­i­can Wind Energy Asso­ci­a­tion, is bound to be dis­missed by wind crit­ics as more industry-funded pro­pa­ganda. But the seven aca­d­e­mic and med­ical experts who con­ducted the analy­sis say they were com­pletely inde­pen­dent in reach­ing their conclusions.

We were not told to find any­thing,” said panel expert David Colby, offi­cer of pub­lic health in Chatham-Kent and a pro­fes­sor of med­i­cine at the Uni­ver­sity of West­ern Ontario. “It was com­pletely open ended.”

Among their findings:

Symp­toms from what some call “wind tur­bine syn­drome” are no dif­fer­ent than symp­toms observed in the gen­eral pop­u­la­tion from the day-to-day stresses of life. These symp­toms include headaches, insom­nia, anx­i­ety, dizzi­ness, and ring­ing in the ears.

All survey-based stud­ies designed to sup­port the exis­tence of wind tur­bine syn­drome are not sci­en­tif­i­cally valid because they have no con­trol group – those who par­tic­i­pate are self-selected and at risk of bias.

The low fre­quen­cies and very low-frequency “infra­sound” that wind tur­bines give off are all around us, whether from out­side traf­fic, the appli­ances that oper­ate in our homes, the beat­ing of our own hearts, or the wind itself. They are not unique, and do not pose a risk to human health.

Colby said the evi­dence was so scant that the wind asso­ci­a­tions have been unable to con­vince gov­ern­ment agen­cies to do their own stud­ies. It’s no sur­prise, he said. “Why would we waste money on doing stud­ies to fur­ther exam­ine this?”

But Ellen Michel­son, a fed­eral Green Party can­di­date for cen­tral Toronto, said the small group of peo­ple with con­cerns shouldn’t be so eas­ily dis­missed. Admit­tedly pro-wind, Michel­son spent a week last month liv­ing near a wind farm in Nor­folk County and said she could occa­sion­ally hear the wind turbines.

It didn’t bother her. “I slept like a baby,” she said. At the same time, she sensed that peo­ple were mostly stressed because of their lack of control.

Colby agreed that lack of con­trol could trig­ger stress, but a line must be drawn somewhere.

You can’t con­trol the amount of cars going by and wind tur­bine noise is gen­er­ally qui­eter than high­way noise.”

The panel included Robert Dobie, a doc­tor and clin­i­cal pro­fes­sor at the Uni­ver­sity of Texas, Geoff Lev­en­thall, a noise vibra­tion and acoustics expert in the United King­dom, Bo Son­der­gaard, with Dan­ish Elec­tron­ics Light and Acoustics, and Michael Seilo, a pro­fes­sor of audi­ol­ogy at West­ern Wash­ing­ton University.

Also on the panel was Robert McCun­ney, a sci­en­tist in the depart­ment of bio­log­i­cal engi­neer­ing at the Mass­a­chu­setts Insti­tute of Tech­nol­ogy, who took issue with claims that low-frequency sounds from tur­bines can cause vibra­tions that impact health. “It doesn’t really have much cre­dence, at least based on the lit­er­a­ture out there,” he said.

The study also explored the power of sug­ges­tion, and how the media’s cov­er­age of alleged wind-turbine sick­ness can cre­ate “antic­i­pa­tory fear” in affected communities.

Robert Hor­nung, pres­i­dent of the Cana­dian Wind Energy Asso­ci­a­tion, said the expert panel is expected to sub­mit the paper this year for pub­li­ca­tion in a peer-reviewed journal.

Being green will soon get a whole lot easier

Alia McMullen, Financial Post

It is not often someone gets to start a power-generation company from the ground up, particularly when that person is fresh out of university. But that is one company among the many that are sprouting from Ontario’s anticipated green experiment – a new direction for an economy suffering the demise of North American manufacturing.

“It’s going to be major,” said Brian Maxwell, a recent economics graduate from Queen’s University and co-founder of NowSolar Inc., who is anxious to hear the terms for Ontario’s new Green Energy Act. The solar power development company Mr. Maxwell and structural engineering graduate Scott Mather started in February is designed to tap into the incoming Feed In Tariff program, a section of the Act that would allow individuals and businesses to sell energy to utility service providers at rates that are the third-highest in the world after Spain and Italy.

Ontario is the first province to offer such a program and the rest of the country is watching closely to see if it pays off. The Act was passed in June but will not take effect until the program’s guidelines have been established, a process the Ministry of Energy and Infrastructure said would take a few more months. Even so, businesses have begun to position themselves to pounce on the new opportunities.

The Feed In Tariff program, for instance, has allowed for the creation of a new type of power-generation company, such as NowSolar. The company’s objective is to build million-dollar solar panel installations on land or roof space rented from individuals and corporations. The company earns money through the energy produced by the solar panels and the lease holder, who is effectively an investor in the project, receives a 10% return on the earnings.

The Ontario Power Authority released draft Feed In Tariff rates on July 8 that vary depending on type and size of a project. Project types include solar, wind, waterpower, biomass, biogas and landfill gas.

“There’s a lot of people just getting into it like us. We have heard of companies being approached by several different parties,” Mr. Maxwell said, noting there has also been interest from large companies from France and Spain.

While there is some movement, companies are anxiously waiting for the release of the official terms, contract details and guidelines before starting their projects. The key concern is what the proposed provincial content requirements will look like. Businesses will need to ensure a set percentage of a project is sourced from Ontario, however the government has not indicated what that will be.

If the percentage is too large, Mr. Maxwell said, it could derail his company’s project. Solar panels are not produced in Ontario and it could take years for a local manufacturer to get up and running, he said.

“We’re in a wait-and-hold period until the final contract comes out,” Mr. Maxwell said.

Amy Tang, a spokeswoman for the Ontario Ministry of Energy and Infrastructure, said the government will take a “balanced approach” to the local-content requirement, which is designed to encourage investment in Ontario. Considerable progress has been made in fine-tuning the regulations since the Act was passed, but a conservative estimate for the release of the details would be in the next couple of months, she said.

Robert Hornung, president of the Canadian Wind Energy Association, said the provincial content requirement is meant to create opportunities for Ontario-based companies to enter the green-energy supply chain, but that businesses in other provinces and countries could take advantage of the Act. He said there were many opportunities for businesses, whether in manufacturing, the supply chain, or services.

“A wind turbine has 8,000 components. There’s a lot of opportunities in the provision of lubricants, lighting systems, bolts, and all sorts of other things. It’s not necessarily that it becomes the dominant feature of a business, but it becomes a new line associated with an industry that is growing quickly.”

The province has the skill set and the equipment to begin to produce entire wind turbines and other renewable technologies, said Ed Bernard, president of XAG Energy Inc., a supply chain management company focused on helping Ontario’s businesses make the transition into renewable energy, particularly those left stranded by the demise of the auto manufacturing industry.

“We’ve got high layoff numbers of highly skilled people. There’s no question that we could build entire turbines right here,” he said.

“But all of the wind turbines we are erecting here in Ontario, they’re all built in Europe.”

He said it cost between $2,000 and $3,000 to transport the turbines from Europe, and production costs are not cheaper. Despite the possibilities, Mr. Bernard contends Ontario businesses generally are not ready to tap the budding renewables market because a lot of manufacturers had depleted their resources when conditions in the sector tightened.

XAG Energy developed an assessment process called NextGen Ready that will help manufacturers transition into renewables.

The range of business that can get involved is wide, Mr. Bernard said, pointing to sectors such as gear box manufacturers, surveyors and mappers, plastic injection moulding, temperature and icing-sensing systems, education and training, metal stamping, and crane operation.

Ontario test case for green experiment

Star­tups pounce

Alia McMullen, Finan­cial Post

It is not often some­one gets to start a power-generation com­pany from the ground up, par­tic­u­larly when that per­son is fresh out of uni­ver­sity. But that is one com­pany among the many that are sprout­ing from Ontario’s antic­i­pated green exper­i­ment — a new direc­tion for an econ­omy suf­fer­ing the demise of North Amer­i­can manufacturing.

It’s going to be major,” said Brian Maxwell, a recent eco­nom­ics grad­u­ate from Queen’s Uni­ver­sity and co-founder of Now­So­lar Inc., who is anx­ious to hear the terms for Ontario’s new Green Energy Act. The solar power devel­op­ment com­pany Mr. Maxwell and struc­tural engi­neer­ing grad­u­ate Scott Mather started in Feb­ru­ary is designed to tap into the incom­ing Feed In Tar­iff pro­gram, a sec­tion of the Act that would allow indi­vid­u­als and busi­nesses to sell energy to util­ity ser­vice providers at rates that are the third-highest in the world after Spain and Italy.

Ontario is the first province to offer such a pro­gram and the rest of the coun­try is watch­ing closely to see if it pays off. The Act was passed in June but will not take effect until the program’s guide­lines have been estab­lished, a process the Min­istry of Energy and Infra­struc­ture said would take a few more months. Even so, busi­nesses have begun to posi­tion them­selves to pounce on the new opportunities.

The Feed In Tar­iff pro­gram, for instance, has allowed for the cre­ation of a new type of power-generation com­pany, such as Now­So­lar. The company’s objec­tive is to build million-dollar solar panel instal­la­tions on land or roof space rented from indi­vid­u­als and cor­po­ra­tions. The com­pany earns money through the energy pro­duced by the solar pan­els and the lease holder, who is effec­tively an investor in the project, receives a 10% return on the earnings.

The Ontario Power Author­ity released draft Feed In Tar­iff rates on July 8 that vary depend­ing on type and size of a project. Project types include solar, wind, water­power, bio­mass, bio­gas and land­fill gas.

There’s a lot of peo­ple just get­ting into it like us. We have heard of com­pa­nies being approached by sev­eral dif­fer­ent par­ties,” Mr. Maxwell said, not­ing there has also been inter­est from large com­pa­nies from France and Spain.

While there is some move­ment, com­pa­nies are anx­iously wait­ing for the release of the offi­cial terms, con­tract details and guide­lines before start­ing their projects. The key con­cern is what the pro­posed provin­cial con­tent require­ments will look like. Busi­nesses will need to ensure a set per­cent­age of a project is sourced from Ontario, how­ever the gov­ern­ment has not indi­cated what that will be.

If the per­cent­age is too large, Mr. Maxwell said, it could derail his company’s project. Solar pan­els are not pro­duced in Ontario and it could take years for a local man­u­fac­turer to get up and run­ning, he said.

We’re in a wait-and-hold period until the final con­tract comes out,” Mr. Maxwell said.

Amy Tang, a spokes­woman for the Ontario Min­istry of Energy and Infra­struc­ture, said the gov­ern­ment will take a “bal­anced approach” to the local-content require­ment, which is designed to encour­age invest­ment in Ontario. Con­sid­er­able progress has been made in fine-tuning the reg­u­la­tions since the Act was passed, but a con­ser­v­a­tive esti­mate for the release of the details would be in the next cou­ple of months, she said.

Robert Hor­nung, pres­i­dent of the Cana­dian Wind Energy Asso­ci­a­tion, said the provin­cial con­tent require­ment is meant to cre­ate oppor­tu­ni­ties for Ontario-based com­pa­nies to enter the green-energy sup­ply chain, but that busi­nesses in other provinces and coun­tries could take advan­tage of the Act. He said there were many oppor­tu­ni­ties for busi­nesses, whether in man­u­fac­tur­ing, the sup­ply chain, or services.

A wind tur­bine has 8,000 com­po­nents. There’s a lot of oppor­tu­ni­ties in the pro­vi­sion of lubri­cants, light­ing sys­tems, bolts, and all sorts of other things. It’s not nec­es­sar­ily that it becomes the dom­i­nant fea­ture of a busi­ness, but it becomes a new line asso­ci­ated with an indus­try that is grow­ing quickly.”

The province has the skill set and the equip­ment to begin to pro­duce entire wind tur­bines and other renew­able tech­nolo­gies, said Ed Bernard, pres­i­dent of XAG Energy Inc., a sup­ply chain man­age­ment com­pany focused on help­ing Ontario’s busi­nesses make the tran­si­tion into renew­able energy, par­tic­u­larly those left stranded by the demise of the auto man­u­fac­tur­ing industry.

We’ve got high lay­off num­bers of highly skilled peo­ple. There’s no ques­tion that we could build entire tur­bines right here,” he said.

But all of the wind tur­bines we are erect­ing here in Ontario, they’re all built in Europe.”

He said it cost between $2,000 and $3,000 to trans­port the tur­bines from Europe, and pro­duc­tion costs are not cheaper. Despite the pos­si­bil­i­ties, Mr. Bernard con­tends Ontario busi­nesses gen­er­ally are not ready to tap the bud­ding renew­ables mar­ket because a lot of man­u­fac­tur­ers had depleted their resources when con­di­tions in the sec­tor tightened.

XAG Energy devel­oped an assess­ment process called NextGen Ready that will help man­u­fac­tur­ers tran­si­tion into renewables.

The range of busi­ness that can get involved is wide, Mr. Bernard said, point­ing to sec­tors such as gear box man­u­fac­tur­ers, sur­vey­ors and map­pers, plas­tic injec­tion mould­ing, tem­per­a­ture and icing-sensing sys­tems, edu­ca­tion and train­ing, metal stamp­ing, and crane operation.
