This paper aims to summarise the current state of knowledge in this area by fire problems with wind turbines. The authors found that fire is the second leading cause of catastrophic accidents in wind turbines (after blade failure) and accounts for 10 to 30% of the reported turbine accidents of any year since 1980’s. In 90% of the cases, the fire leads to a total loss of the wind turbine, or at least a downtime that results in the accumulation of economic losses.The Abstract and Conclusions of the paper are provided below.

The Finland Ministry of Social Affairs and Health prepared this report in order to ensure health protection is involve in connection with the planning and construction of wind power plants. A major objective of health protection is also to prevent health hazards. According to the Ministry, "the cheapest and absolutely best way of implementing health protection is hazard prevention as early as at the planning stage." Excerpts of the report are provided below.

This attached documents show production data from a large sample of wind projects operating in the US, by state, for the years 2011, 2012 and 2013. The production numbers were obtained from the Energy Information Administration.
Texas PUC chairwoman, Donna Nelson, has initiated an investigation into "the costs of [transmission] system upgrades, the costs to maintain and operate the current system, and the allocation of those costs specifically related to renewable resources." In her memo below (and attached). Chairwoman Nelson warns of the costs, particularly of the wind PTC is extended by Congress.
The proximity of wind turbines to residential areas has been associated with a higher level of complaints compared to the general population. The study objective was to search the literature investigating whether an association between wind turbines and human distress exists. This report examined eighteen (18) peer-reviewed studies and found that each study provided reasonable evidence that an association exists. The abstract of the report is provided below. The full report can be accessed by clicking the link(s) on this paper.
This paper examines five different low and no-carbon electricity technologies and presents the net benefits of each under a range of assumptions. One of the key findings of the report states that "nuclear, hydro, and natural gas combined cycle have far more net benefits than either wind or solar. This is the case because solar and wind facilities suffer from a very high capacity cost per megawatt, very low capacity factors and low reliability, which result in low avoided emissions and low avoided energy cost per dollar invested." A summary of the findings is below. The full report can be accessed by clicking the links at the bottom of this page.

The American Bird Conservancy has notified the Obama Administration that it intends to file a lawsuit challenging recent changes in wildlife protection laws allowing wind farms that kill eagles accidentally to continue operating for a period of 30 years without needing to apply for new permits. The intent to sue document filed with the Department of the Interior can be accessed by clicking the link(s) on this page.
Abstract This study provides quantitative evidence on the local benefits and costs of wind farm developments in England and Wales, focussing on their visual environmental impacts. In the tradition of studies in environmental, public and urban economics, housing costs are used to reveal local preferences for views of wind farm developments. Estimation is based on quasiexperimental research designs that compare price changes occurring in places where wind farms become visible, with price changes in appropriate comparator groups. These comparator groups include places close to wind farms that became visible in the past, or where they will become operational in the future and places close to wind farms sites but where the turbines are hidden by the terrain. All these comparisons suggest that wind farm visibility reduces local house prices, and the implied visual environmental costs are substantial. The conclusions of the report are provided below.

Developers should also be aware that the case clarifies the way in which the planning balance must be struck by decision makers. They are not free to give harm to heritage assets such weight as they may choose when carrying out the balancing exercise. Instead, they must give particular weight the desirability of avoiding such harm when assessing whether the advantages of the proposal outweigh that harm. The rejection of the "reasonable observer" test will also be a significant constraint on the ability to construct wind farms and other new development in sensitive locations.
Mauri Johansson, MD, a specialist in Community and Occupational Medicine (including Environmental Medicine) in Denmark, sent this open letter to the heads of the Australian Medical Association in response to the AMA's recent position paper on industrial-scale wind energy where it claimed that "Individuals residing in the vicinity of wind farms who do experience adverse health or well-being, may do so as a consequence of their heightened anxiety or negative perceptions regarding wind farm developments in their area."
This important paper written by Drs. Alec Salt and Jeffery T. Lichtenhan, both Professors of Otolaryngology at Washington University in St. Louis, examines the many ways by which unheard infrasound and low-frequency sound from wind turbines could distress people living nearby.

Dr. Bruce Rapley filed this response letter with the Australian Medical Association (AMA) objecting to the AMA's position on wind turbine noise that the "available Australian and international evidence does not support the view that the infrasound or low frequency sound generated by wind farms, as they are currently regulated in Australia, causes adverse health effects on populations residing in their vicinity." The concluding paragraphs of the letter are posted below. The full letter can be accessed by clicking the links on this page.

Dr. Gary Hopkins, a practicing physician in Australia, issued this letter to the President of the Australian Medical Association where he takes the AMA to task over its recent position statement claiming that "available Australian and international evidence does not support the view that the infrasound or low frequency sound generated by wind farms, as they are currently regulated in Australia, causes adverse health effects on populations residing in their vicinity."
Dr. Jay Tibbetts, a practicing physician, member of the Brown County Board of Health and Medical Adviser to the Brown County Health Department responds to the Australian Medical Association's position on wind power and the impacts on human health.
Senator John Madigan delivered this powerful speech on the floor of the Australian Federal Senate. In this speech, he details how one of Australia’s best known power companies, AGL, attempted to influence country doctors in their treatment of residents living near Macarthur wind farm.
In this District Court ruling, Judge Reggie Walton found that the U.S. Fish and Wildlife Service (FWS) and the National Marine Fisheries Service (NMFS) violated the Endangered Species Act (ESA) in their reviews of the offshore wind project. The court remanded the case to FWS to independently evaluate a shutdown of turbines during migratory bird season. The court also ruled that NMFS can no longer avoid fully evaluating impacts to right whales and must formulate and issue an incidental take statement because of the documented presence of this highly endangered species in the area. The conclusion of the ruling is provided below. The full ruling can be accessed by clicking the link on this page.
