Introduction
Better siting criteria
Given both the benefits and the concerns raised about wind energy,
my 390 requirements was to come up with an appropriate siting criteria that suits both sides of the divide

Efficiency of Installed Capacity
Issues Regarding Site Selection
• . Land use restrictions or zoning issues, such as hunting rights, grazing rights, and cultural considerations limit the site
• Wildlife issues may also restrict construction due to avian and wildlife migration, spawning grounds, wetlands and surface water concerns
• Noise or visual impact restrictions may affect placement of turbines

Weather Limitations
09/20/2012 30
Efficiency of Installed Capacity
Weather LimitationsLow Temperature: The mechanical properties of structural elements such as steel and composite material change at low temperatures.
Steel becomes more brittle; its energy absorbing capacity and deformation prior to failure are both reduced
Low temperature also increases the stress on composites. The stress can result in micro-cracking.
These micro cracks reduce both the stiffness and the impermeability of the material, which can contribute to the deterioration process .
Snow: It can infiltrate almost any unprotected openings where airflow can find its way.
On the other hand, snow could also obstruct these openings and prevent normal circulation of air

Health Issues related to IWTs
Challenges of Wind
industry
The range of health grievances has previously not been described in any medical literature.
However , there have been an increase in the number of health related complaints made after the turbines are operational.
To the point that Health Canada has decided to study the possible connection between noise generated by the towering turbines and adverse health effects reported by people living close to them in conjunction with Statistics Canada.
Results to be published in 2014.
Examples of alleged symptoms : Severe chronic sleep deprivation, severe frequent headaches, tinnitus , ear pressure sensations , hyperacusis, nausea, motion sickness, vertigo symptoms, and balance disturbances, High blood pressure etc..

Property value Issues related to IWTs
Challenges of Wind
industry
While no national study has been done, An independent study
conducted by Appraisal Group One (AGO) accessed the existing
literature on wind turbine impact on sales, an opinion survey of
realtors to learn their take on the impact of wind turbines in their
sales area and a sales study which compared vacant residential lot
sales within the wind turbine farm area to comparable sales
located outside of the turbine influence.
Reduces by about 20-30%
AGO is an appraisal company specializing in forensic appraisal, eminent domain, stigmatized properties and valuation research.

Driving Traffic to the Site
Challenges of Wind
industry
• Leveraging the diverse MEM class who are all on Facebook and twitter to spread word about the site.
• I have joined certain list serves that are both for and against wind turbines to spread word.

Authenticity of Reports Submitted
Challenges of Wind
industry
The only safeguards now are:
• People’s integrity
• Fill out a form with your email address and location. Multiple reports from the same email address will be a red flag

Choosing a site
Challenges of Wind
industry
1. Area with good wind resource2. Area with good transportation
system3. Area where snow and ice wont be
that big of an issue during the winter4. A place where there isn’t that much
opposition to the construction of wind turbines based on the global red flags that the online reporting system will generate.

Efficiency of Installed Capacity
Capital and Power CostEstimated capital cost $1.5 million
Actual capital cost $2 million; an overrun of 33%
The project was financed by UM cash reserves and a $50,000 cash subsidy from the Maine Public Utilities Commission.
The estimated useful service life was about 20 years.Predicted power production: 1,000,000 kWh/yrPredicted capacity factor = 1,000,000 kWh/yr)/ (600 kW x 8,760 hr/yr) = 0.190 Actual power production after 1 year: 609,250 kWhActual capacity factor for 1 year = 609,250 kWh/yr/ (600 kW x 8,760 hr/yr) = 0.116; a shortfall of 39%
Value of power produced = 609,250 kWh/yr x $0.125/ kWh = $76,156/yr; if O&M and financing costs amortized over 20 years are subtracted, this value will likely be negative.
