Slide 1

Reacting to Concerns about Wind Energy Sean Whittaker, P.Eng Policy Director, Canadian Wind Energy Association (CanWEA) August 14, 2007

Slide 2

Overview About CanWEA Our exercises and participation Status of twist in Canada Current and anticipated introduced limit Addressing worries about wind What concerns are brought by nationals and up in the media? What are the truths around each issue? Placing it in setting Public view of wind Summary References

Slide 3

Slide 5

Status of Wind in Canada

Slide 6

Global Wind Energy Snapshot Wind on the planet: 1995: 4,800 MW of introduced wind vitality limit 2006: 74,000 MW of wind limit = 22 million homes (15,200 MW were introduced in 2005 alone) 2010: no less than 136,000 MW expected A developing industry: Fastest developing wellspring of new power era More than $US 14 billion put worldwide in 2005 150,000 individuals now work in the worldwide wind vitality industry

Slide 7

Current introduced limit Capacity introduced starting at July 2007 = 1,588 Megawatts (MW) = 0.6 % of national request = 480,000 homes Capacity introduced in 2006 = 776 MW (new record) Contracted/under development = 2,700 MW

Slide 8

Future Prospects for Wind in Canada Provincial targets speak to at least 5,000 MW by 2010 and 10,000 MW by 2015: Quebec – 4,000 MW by 2016 Ontario – 5,000 MW by 2020 Manitoba – 1,000 MW by 2016 Alberta – 900 MW edge to be expelled New Brunswick – 400 MW by 2016 PEI – 200 MW by 2015 Provinces, for example, BC and Alberta don't have formal targets however are both liable to be more than 1,000 MW certainly before 2015

Slide 9

10,000 MW in 2015 150 Means that wind will give 3.7% of Canada's power by 2015 10,000 MW of wind vitality still just beginning to expose what's underneath of Canada's wind vitality potential 4000 900 1000 200 330 2400 400 380 200

Slide 10

Addressing worries about wind

Slide 11

What we find in the media The great: " That sound above St. Leon is twist blowing in cash" - Winnipeg Free Press, March 2006 "Answer's blowing in the twist", Letter to the editorial manager, WFP Aug 9 The terrible: "Wind turbines bringing about inconvenience in country regions: Sound of quiet gone perpetually", Winnipeg Free Press, July 18 "Proposed wind cultivate explodes a tempest in the Dacotah territory", Winnipeg Free Press, July 9 The monstrous: " Opponents Complain Of High Cost, Inefficiency, Noise And Disruption Of Birds' Migration" - National Post, July 31

Slide 12

Concerns around wind The wind business considers these important: Public concerns are reasonable and they are not out of the ordinary with any innovation that is new to the social, political and monetary scene Key is to guarantee that great choices are made on great data … and great science Can't name everybody that raises worry as a "NIMBY" Important to recognize: Fact and fiction Quantitative (science-based) and subjective (judgment-based) issues

Slide 13

The Issues Audible sound Low recurrence sound ("infrasound") Environmental effects (winged animals and bats) Property estimations Impacts on farming practices Visual effects Setback separations Interference with media communications Reliability Economics

Slide 14

Audible sound What concerns are raised: "Turbines radiate a shocking commotion that makes it difficult to live anyplace close them" What we know: Wind turbines do deliver sound ("swoosh" of cutting edges) Actual sound level is affected by many components including the kind of turbine, wind speed, encompassing geology How we address these worries: Projects must meet administrative prerequisites for sound All wind ventures experience nitty gritty sound demonstrating Best Practices in light of sound at receptor as capacity of wind speed: 40 dBA at 4 m/s ascending to 53 dBA at 11 m/s Acceptable division separations for sound are by and large 300 to 600 m (can be less to participate landowners)

Slide 15

Infrasound and Amplitude Modulation What concerns are raised: "Low recurrence sound purposes medical issues" What we know: Peer-inspected ponders shows that levels created are like surrounding levels pervasive in the common habitat and underneath levels known to affect human wellbeing. Thorough review in the U.K. taken a gander at 133 windfarms - presumed that "regardless of press articles in actuality, the occurrence of windfarm clamor and AM in the UK is low." Study likewise found that mechanical grievances happen 10,000 - 100,000 circumstances all the more regularly How we address these worries: Present companion assessed truths on subject (right now, there is minimal logical premise to bolster charges of negative effects on human wellbeing or nature)

Slide 16

Environmental effects (avian) What concerns are raised: "Wind turbines are a noteworthy risk to flying creatures and bats" What we know: Wind turbines can conceivably have impacts on winged animals and bats through crashes and living space interruption Impact is significantly less than that of structures, house felines or the climatic changes that are affecting many fledgling living spaces. The National Audubon Society: "On adjust, Audubon unequivocally bolsters twist control as a spotless option vitality source that lessens the danger of an unnatural weather change" Limited number of instances of high bat mortality at wind cultivates; the causes are not yet completely seen How we address these worries: The key is appropriate siting and understanding avian conduct Wind ranches must get endorsement from Federal and Provincial ecological appraisal forms Industry working with Bat Conservation International to better comprehend impacts on bats

Slide 17

Property Values What concerns are raised: "Wind turbines will decrease the estimation of homes in the region" What we know: Issue has been concentrated more in the U.S. than Canada (basically in light of the fact that there is more verifiable information) Some reviews demonstrate property estimations expanding and others indicate them declining Study by Renewable Energy Policy Project (REPP) in the U.S. was a standout amongst the most exhaustive – it found: "no confirmation that property estimations diminished accordingly of wind homesteads [… ] for the immense greater part of activities the property estimations really climbed more rapidly in the view shed than they did in the practically identical group. In addition, values expanded quicker in the view shed after the ventures came online than they did before." How we address these worries: CanWEA undertaking a venture of comparative extension taking a gander at Canadian establishments

Slide 18

Impacts on horticultural practices What concerns are raised: "Wind turbines meddle with harvest dusters and generally upset how ranchers utilize their territory" What we know: Turbines just possess 5% of the land, and steers regularly touch up to the base of the turbines Extra wage from turbines bolsters rural exercises (wind is upheld by gatherings, for example, John Deere and different agribusiness alliances) Some have guaranteed that turbines add up to "no fly zones" – this is patently false as indicated by Transport Canada How we address these worries: Providing data to agriculturists and engineers Wind engineers need to act proactively with agriculturists and yield dusters to encourage edit tidying when and where fitting

Slide 19

Impacts on rural practices

Slide 20

Visual Impacts What concerns are raised: "Wind turbines will harm the scene" What we know: "Magnificence is subjective depending on each person's preferences" Early counsel and engagement are key – issue is regularly attached to worries around property estimation There are many apparatuses accessible to help a promoter and group in outlining a twist homestead to limit visual effects, and safeguard certain viewscapes Developer can move turbine area to suit group wishes (clearly, to a point) How we address these worries: This is venture particular and completely subjective Encourage early and visit discussions amongst designers and groups

Slide 21

Setback Distances What concerns are raised: "Mishaps of one to two kilometers are required amongst turbines and homes to guarantee they are not an annoyance" What we know: Setbacks amongst turbines and abodes ought to be founded on sound levels (by and large satisfactory: 300 – 600 meters) Setbacks amongst turbines and streets/property lines ought to be founded on security – e.g. ice shedding or turbine disappointment (for the most part worthy: cutting edge length + 10 m) How we address these worries: Currently building up a position on mishaps in Ontario – it is for the most part considered that this will shape the reason for a national standard Need to work with districts and metropolitan relationship to guarantee that difficulties depend on Best Practices

Slide 22

Interference with media communications What concerns are raised: "Wind turbines meddle with radar and TV frameworks" What we know: In specific conditions, wind turbines can contrarily influence radio, broadcast communications, radar or seismoacoustic frameworks inside a specific separation of the turbines Must guarantee adequate misfortunes from thes
