The Pembina Institute: Behind the switch: pricing Ontario electricity options
A major new report released by the Pembina Institute examines how scaling back Ontario's plans to develop renewable energy would affect electricity prices.
Behind the switch: pricing Ontario electricity options finds that Ontario consumers would see virtually no relief from high electricity prices if the province cancelled its support for renewable energy under the Green Energy Act. In fact, the study indicates that investing in renewable energy today is likely to save Ontario ratepayers money within the next 15 years, as natural gas becomes more expensive and as the cost of renewable energy technology continues to decrease.

Health Effects and Wind Turbines: A Review of the Literature. Environmental Health
On September 14, 2011, Drs. Loren Knopper and Christopher Ollson of Intrinsik Environmental Sciences published the following peer-reviewed scientific article in the journal Environmental Health:
Knopper, L.D. and Ollson, C.A. 2011. Health Effects and Wind Turbines: A Review of the Literature. Environmental Health, 10:78. The article can be viewed here:
Since publication, the article is already listed as one of the most viewed and most forwarded.
Chris and Loren will be giving an invited talk "Wind Turbines and Human Health" at the upcoming CanWEA Annual Conference in Vancouver on October 3rd and will be available to discuss their findings.
Briefly, the purpose of the paper was to review the peer-reviewed scientific literature, government agency reports, and the most prominent information found in the popular literature in terms of wind turbines and human health. The authors found that conclusions of the peer reviewed literature differed in some ways from those in the popular literature. In peer reviewed studies, wind turbine annoyance has been statistically associated with wind turbine noise, but found to be more strongly related to visual impact, attitude to wind turbines and sensitivity to noise.
To date, no peer reviewed articles demonstrate a direct causal link between people living in proximity to modern wind turbines, the noise they emit and resulting physiological health effects. If anything, reported health effects are likely attributed to a number of environmental stressors that result in an annoyed/stressed state in a segment of the population.

Wind Turbine Sound and Health Effects: An Expert Panel
An international panel of experts jointly established by CanWEA and AWEA has released a report based on a review of a large body of scientific literature on sound and health effects, and specifically with regard to sound produced by wind turbines.
Australia: Wind Turbine Technical Paper - Experts Silence Wind Farm Noise
An independent Australian report prepared by acoustic consultancy Sonus and commissioned by the Clean Energy Council finds that there are no direct health effects from living near operating wind farms. The Wind Farm Technical Paper reinforces existing independent research, concluding that there is extensive evidence that sound from wind farms developed and operated in accordance with the current standards and guidelines will not have any direct adverse health effects.
The objectives of this study are to examine whether proximity to the 240-turbine, Twin Groves wind farm in eastern McLean County, Illinois, has impacted nearby residential property values and whether any impact on nearby property values remains constant over different stages of wind farm development. The study found prices were negatively affected before the wind farm was built, but rebound after it was in place.

CanWEA contracted the services of Canning Consultants Inc. and John Simmons Realty Services Ltd., to prepare a report that evaluates the effect of wind turbines on real estate values in the Municipality of Chatham-Kent. The study was prepared in accordance with the Canadian Uniform Standards of Professional Appraisal Practice for the Appraisal Institute of Canada, and applied a statistical Multiple Regression Analysis (MRA) model using real property transaction data, in arriving at its conclusions.
The CanWEA Property Value Study, finds that there is no statistical evidence to demonstrate that wind farms negatively affect rural residential market values in the Chatham-Kent area.
A major new report released by the U.S. Department of Energy’s (DOE) Lawrence Berkeley National Laboratory finds that neither the view of the wind facilities nor the distance of the home to those facilities is found to have any consistent, measurable, and statistically significant effect on home sales prices. Although the analysis cannot dismiss the possibility that individual homes or small numbers of homes have been or could be negatively impacted, it finds that if these impacts do exist, they are either too small and/or too infrequent to result in any widespread, statistically observable impact.
Statements by Regional Authorities on Wind Turbines and Safety
Statement by Dr. Isra Levy
Medical Officer of Health, Ottawa Public Health
In this memo to the Agriculture and Rural Affairs Committee, Dr. Isra Levy, Medical Officer of Health from the Ottawa Public Health, states that “The Ontario government has fulfilled the request by Ottawa City Council to conduct a comprehensive review of the available peer-reviewed medical literature regarding wind turbine related health issues. The review did not find evidence of health effects that would warrant public health interventions at this point in time. Ottawa Public Health will continue to follow the work of experts and provincial ministries tasked with studying this emerging issue.”

Fact Sheet – Wind Power Realities
Putting Wind Power Myths into Perspective
Produced by Tim Weis, Director of Renewable Energy for the Pembina Institute
As new opportunities emerge to develop wind-power generation in communities across Canada, they raise reasonable questions about the social, environmental and economic impacts of large-scale wind power production. This fact sheet aims to help answer those questions, and to distill the realities of wind power from the myths and misconceptions.
Danish system operator hits back at US think tank claims over wind power
Electricity sold or exported from Denmark at any one time cannot be said to emanate from any specific source of generation, says Denmark's power system operator, Energinet.dk. For that reason it is impossible to claim that electricity from any particular source is being sold for a specified price. The company's statements were made in response to a report released last month by a Danish right-wing think tank, the Centre for Political Studies (Cepos), in collaboration with the Institute for Energy Research (IER), an American oil and coal lobby group.
