The report describes an application of ontologies to the analysis of wind turbine manufacturing data. We show how applying ontologies to composite materials data may facilitate the discovery of optimum composite material designs that will deliver maximum wind turbine blade performance within environmental constraints.

Through the case of the Helix_T wind turbine project, this article sets out to argue two points: first, on a theoretical level, that Commons-based peer production, in conjunction with the emerging technological capabilities of three-dimensional printing, can also produce promising hardware, globally designed and locally produced. Second, the Commons-oriented wind turbine examined here is also meant to practically contribute to the quest for novel solutions to the timely problem of the need for renewable sources of energy, (...) more in the sense of a development process than as a ready-to-apply solution. We demonstrate that it is possible for someone with partial initial knowledge to initiate a similar, complex project based on an interesting idea, and to succeed in implementing it through collaboration with Commons-oriented communities, while using peer-produced products and tools. Given the trends and trajectories both of the current information-based paradigm and the problems of the predominant industrial modes of production with all the collateral damage they entail, this may be considered a positive message indeed.

Wind turbines have been used by many groups of humans for many centuries. Wind turbines have allowed groups of humans to perform many different tasks in the past. However, only a century and a half ago, they began to be used to convert the energy captured from wind into electric energy. Moreover, only approximately twenty-five years ago, we started to introduce on a massive scale the energy generated from wind turbines into the electric networks of most (...) developed countries in the world for regular consumption. According to 2017 statistics, approximately 12 percent of the electric energy consumed in the EU is produced by wind turbines. Despite the fact that wind turbines generally appear quite similar externally—i.e., a three-blade structure, a nacelle, a tower, etc.—if we carefully examine the electric technology used within them, we find quite a wide range of technologies for energy conversion, which is a key issue in wind turbine technology. Hence, this paper adopts a dialectic perspective towards analyzing and understanding why several electric technologies coexist in wind turbine technology. We explain the specific factors that have influenced different wind turbine manufacturers to adopt different electric technologies across the last twenty-five years. We show how their actions and the technological directions that have followed have been mutually codetermined, resulting in a technological evolution that has produced today’s wind turbine variety.

People who live near wind turbines complain of symptoms that include some combination of the following: difficulty sleeping, fatigue, depression, irritability, aggressiveness, cognitive dysfunction, chest pain/pressure, headaches, joint pain, skin irritations, nausea, dizziness, tinnitus, and stress. These symptoms have been attributed to the pressure (sound) waves that wind turbines generate in the form of noise and infrasound. However, wind turbines also generate electromagnetic waves in the form of poor power quality (dirty electricity) and ground current, and these (...) can adversely affect those who are electrically hypersensitive. Indeed, the symptoms mentioned above are consistent with electrohypersensitivity. Sensitivity to both sound and electromagnetic waves differs among individuals and may explain why not everyone in the same home experiences similar effects. Ways to mitigate the adverse health effects of wind turbines are presented. (shrink)

Industrial wind turbines are frequently thought of as benign. However, the literature is reporting adverse health effects associated with the implementation of industrial-scale wind developments. This article explores the historical evidence about what was known regarding infra and low-frequency sound from wind turbines and other noise sources during the period from the 1970s through the end of the 1990s. This exploration has been accomplished through references, personal interviews and communications, and other available documentation. The application of past (...) knowledge could improve the current siting of industrial wind turbines and avoid potential risks to health. (shrink)

Wind turbines produce sound that is capable of disturbing local residents and is reported to cause annoyance, sleep disturbance, and other health-related impacts. An acoustical study was conducted to investigate the presence of infrasonic and low-frequency noise emissions from wind turbines located in Falmouth, Massachusetts, USA. During the study, the investigating acousticians experienced adverse health effects consistent with those reported by some Falmouth residents. The authors conclude that wind turbine acoustic energy was found to be greater (...) than or uniquely distinguishable from the ambient background levels and capable of exceeding human detection thresholds. The authors emphasize the need for epidemiological and laboratory research by health professionals and acousticians concerned with public health and well-being to develop effective and precautionary setback distances for industrial wind turbines that protect residents from wind turbine sound.

This article explores the loss of social justice reported by individuals living in the environs of industrial wind turbines (IWTs). References indicate that some individuals residing in proximity to IWT facilities experience adverse health effects. These adverse health effects are severe enough that some families have abandoned their homes. Individuals report they welcomed IWTs into their community and the negative consequences were unexpected. Expressions of grief are exacerbated by the emotional and physical toll of individuals’ symptoms, loss of enjoyment (...) of homes and property, disturbed living conditions, financial loss, and the lack of society’s recognition of their situation. The author has investigated the reported loss of social justice through a review of literature, personal interviews with, and communications from, those reporting adverse health effects. The author’s intention is to create awareness that loss of social justice is being associated with IWT development. This loss of justice arises from a number of factors, including the lack of fair process, the loss of rights, and associated disempowerment. These societal themes require further investigation. Research by health professionals and social scientists is urgently needed to address the health and social impacts of IWTs operating near family homes. (shrink)

Following an introduction to noise and noise regulation of wind turbines, the problem of adverse health effects of turbine noise is discussed. This is attributed to the characteristics of turbine noise and deficiencies in the regulation of this noise. Both onshore and offshore wind farms are discussed.

Research linking loud sounds to hearing loss in youngsters is now widespread, resulting in the issuance of warnings to protect children’s hearing. However, studies attesting to the adverse effects of intrusive sounds and noise on children’s overall mental and physical health and well-being have not received similar attention.This, despite the fact that many studies have demonstrated that intrusive noises such as those from passing road traffic, nearby rail systems, and overhead aircraft can adversely affect children’s cardiovascular system, memory, language development, (...) and learning acquisition. While some schools in the United States have received funds to abate intrusive aircraft noise, for example, many schools still expose children to noises from passing traffic and overhead aircraft. Discussion focuses on the harmful effects of noise on children, what has to be done to remedy the situation, and the need for action to lessen the impacts of noise from all sources. Furthermore, based on our knowledge of the harmful effects of noise on children’s health and the growing body of evidence to suggest the potential harmful effects of industrial wind turbine noise, it is strongly urged that further studies be conducted on the impacts of industrial wind turbines on their health, as well as the health of their parents, before forging ahead in siting industrial wind turbines.

This chapter argues that our ambiguity toward renewable technologies arises from our understanding that the nature of the machine is somehow alien and external to us. Historically, we have thought of the machine as lacking cultural signification. As a result, the machine has been relegated to mere utility rather than having any axiological or human reality. Thinking of the machine as utterly other has exercised a certain xenophobia or misoneism as well as an uncritical technophilia. This ambiguity arises from our (...) acceptance that technology is based on the principle of conservation, a sameness underlying change that is traceable to Aristotle’s theory of causality with its implicit ontological distinction between natural and human made objects. To overcome such teleology, we need a different ontological ground on which to consider the concept of technology. Gilbert Simondon gives us such tools. His work is slowly surfacing with thinkers such as Bernard Stiegler and more recently in the English-speaking academy with thinkers such as Elizabeth Grosz and Andrew Feenberg. 1 This chapter will show how both Aristotle’s phenomenology of technology and Simondon’s ontogenesis can help to think though the challenges of renewable technologies associated with climate change. It will outline Aristotle’s phenomenology of technology and illustrate the intersection and departure of Simondon’s ontogenetic epistemology through his three-phase principle of individuation: elemental phase, individual phase, and ensemble phase. For Simondon all objects become whole (sunolos) though a process of individuation, which explains the coming into being and the existence of beings of all kinds. There are three phases: the elemental which is the spontaneous excess of being; individuation is the successive multistability of being where being splits becoming both the individual and the many; and finally the ensemble .

Industrial wind turbines (IWTs) are a new source of community noise to which relatively few people have yet been exposed. IWTs are being erected at a rapid pace in proximity to human habitation. Some people report experiencing adverse health effects as a result of living in the environs of IWTs. In order to address public concerns and assess the plausibility of reported adverse health effects, a number of literature reviews have been commissioned by various organizations. This article explores some (...) of the recent literature reviews on IWTs and adverse health effects. It considers the completeness, accuracy, and objectivity of their contents and conclusions. While some of the literature reviews provide a balanced assessment and draw reasonable scientific conclusions, others should not be relied on to make informed decisions. The article concludes that human health research is required to develop authoritative guidelines for the siting of IWTs in order to protect the health and welfare of exposed individuals. (shrink)

Industrial wind turbines (IWTs) are being installed at a fast pace globally. Researchers, medical practitioners, and media have reported adverse health effects resulting from living in the environs of IWTs. While there have been some anecdotal reports from technicians and other workers who work in the environs of IWTs, little is known about the occupational health sector. The purpose of this case study is to raise awareness about the potential for adverse health effects occurring among workers. The authors propose (...) that there is a need for research regarding occupational worker exposure relating to IWTs. (shrink)

Wind turbines generate low-frequency sounds that affect the ear. The ear is superficially similar to a microphone, converting mechanical sound waves into electrical signals, but does this by complex physiologic processes. Serious misconceptions about low-frequency sound and the ear have resulted from a failure to consider in detail how the ear works. Although the cells that provide hearing are insensitive to infrasound, other sensory cells in the ear are much more sensitive, which can be demonstrated by electrical recordings. Responses (...) to infrasound reach the brain through pathways that do not involve conscious hearing but instead may produce sensations of fullness, pressure or tinnitus, or have no sensation. Activation of subconscious pathways by infrasound could disturb sleep. Based on our current knowledge of how the ear works, it is quite possible that low-frequency sounds at the levels generated by wind turbines could affect those living nearby. (shrink)

Community acceptance still remains a challenge for wind energy projects. The most popular explanation for local opposition, the Not in My Backyard effect, has received fierce criticism in the past decade. Critics argue that opposition is not merely a matter of selfishness or ignorance, but that moral, ecological and aesthetic values play an important role. In order to better take such values into account, a more bottom-up, participatory decision process is usually proposed. Research on this topic focusses on either (...) stakeholder motivations/attitudes, or their behavior during project implementation. This paper proposes a third research focus, namely the ‘objects’ which elicit certain behavioral responses and attitudes—the wind turbine and parks. More concretely, this paper explores Value Sensitive Design as way to arrive at wind turbines and parks that better embed or reflect key values. After a critical discussion of the notion of acceptance versus acceptability and support, the paper discusses existing literature on ecology and aesthetics in relation to wind turbine/park design, which could serve as ‘building blocks’ of a more integral VSD approach of the topic. It also discusses the challenge of demarcating wind park projects as VSD projects. A further challenge is that VSD has been applied mainly at the level of technical artifacts, whereas wind parks can best be conceptualized as socio-technical system. This new application would therefore expand the current practice of VSD, and may as a consequence also lead to interesting new insights for the VSD community. The paper concludes that such an outcome-oriented approach of wind turbines and park is worth exploring further, as a supplement to rather than a replacement of the process-oriented approach that is promoted by the current literature on community acceptance of wind parks.

In recent years, a growing number of small-to-medium-enterprises are embracing wind turbine projects not only as part of their cost reduction strategy but also to actively play their part in the global fight against climate change. However, it would appear there are currently limited empirical studies carried out in this emerging industry. This case study analyses the cost effectiveness of one such wind turbine initiative by a company in the Republic of Ireland, who invested in a (...) 300 kW embedded wind turbine project at the end of 2013. The research methodology which is primarily a case study analysis included comparing historical electricity utility bills which allowed the 2013 quantity of electrical energy units imported, i.e. the year before the turbine was installed to be compared with the 2014 value, i.e. the year after the turbine was installed. Numerous site visits were undertaken over a four-year period, during which electric meter readings were recorded and stored. The findings of this piece of research indicate that the installation of the embedded wind turbine had minimal positive effect on the annual electricity costs for the company. Indeed the turbine appears to have significant negative effects such as a need for an increased maximum import capacity and also it appeared to contribute to a deteriorating utility power factor. While the aesthetic nature of the on-site turbine seemed to create a positive image of the company, it would appear that caution should be exercised when business owners select alternative energy providers who claim to be experts in the energy field but may have limited knowledge in this area of wind energy, which as of yet has minimal robust research into all aspects of its benefits/attributes.

Industrial wind turbines have been operating in many parts of the globe. Anecdotal reports of perceived adverse health effects relating to industrial wind turbines have been published in the media and on the Internet. Based on these reports, indications were that some residents perceived they were experiencing adverse health effects. The purpose of the WindVOiCe health survey was to provide vigilance monitoring for those wishing to report their perceived adverse health effects. This article discusses the results of a (...) self reporting health survey regarding perceived adverse health effects associated with industrial wind turbines. (shrink)

Internationally, there are reports of adverse health effects (AHE) in the environs of industrial wind turbines (IWT). There was multidisciplinary confirmation of the key characteristics of the AHE at the first international symposium on AHE/iwt. The symptoms being reported are consistent internationally and are characterized by crossover findings or a predictable appearance of signs and symptoms present with exposure to IWT sound energy and amelioration when the exposure ceases. There is also a revealed preference of victims to seek restoration (...) away from their homes. This article identifies the need to create a case definition to establish a clinical diagnosis. A case definition is proposed that identifies the sine qua non diagnostic criteria for a diagnosis of adverse health effects in the environs of industrial wind turbines. Possible, probable, and confirmed diagnoses are detailed. The goal is to foster the adoption of a common case definition that will facilitate future research efforts. (shrink)

While industrial wind turbines (IWTs) clearly raise issues concerning threats to the health of a few in contrast to claimed health benefits to many, the trade-off has not been fully considered in a public health framework. This article reviews public health ethics justifications for the licensing and installation of IWTs. It concludes that the current methods used by government to evaluate licensing applications for IWTs do not meet most public health ethical criteria. Furthermore, these methods are contrary to widely (...) held fundamental principles of administrative law and governmental legitimacy. A set of decision-making principles are suggested to address this situation that are derived from existing and emerging legal principles in Canada and elsewhere. These include the Precautionary Principle, the Least Impactful Means (Proportionality) Test, and the Neighbor Principle. (shrink)

There is overwhelming evidence that wind turbines cause serious health problems in nearby residents, usually stress-disorder-type diseases, at a nontrivial rate. The bulk of the evidence takes the form of thousands of adverse event reports. There is also a small amount of systematically gathered data. The adverse event reports provide compelling evidence of the seriousness of the problems and of causation in this case because of their volume, the ease of observing exposure and outcome incidence, and case-crossover data. Proponents (...) of turbines have sought to deny these problems by making a collection of contradictory claims including that the evidence does not “count,” the outcomes are not “real” diseases, the outcomes are the victims’ own fault, and that acoustical models cannot explain why there are health problems so the problems must not exist. These claims appeared to have swayed many nonexpert observers, though they are easily debunked. Moreover, though the failure of models to explain the observed problems does not deny the problems, it does mean that we do not know what, other than kilometers of distance, could sufficiently mitigate the effects. There has been no policy analysis that justifies imposing these effects on local residents. The attempts to deny the evidence cannot be seen as honest scientific disagreement and represent either gross incompetence or intentional bias. (shrink)

The harmful consequences of fossil fuels use has resulted in the promotion of clean and renewable energies. During the past decades, green technologies have experienced a strong development, paying especial attention to wind energy, that covers a significant share of the electric energy demand. In this context, the main efforts are focused on the optimization of wind generator facilities, not only in the mechanic design but also in the energy management. Then, the present work deals with the prediction (...) of the energy generated in a small wind turbine placed in a bioclimatic house located on the north west region of Spain. This includes an analysis of the characteristics of the atmospheric variables registered during the turbine operation for a period of one year and an exploratory examination of a range of regression techniques in order to assess the suitability of using the registered information to predict the installation’s power generation levels on the short term. The study detailed in this work proves that this objective is an attainable one with a good degree of accuracy. (shrink)

Bird kill rate and disruption of habitat has been reported when industrial wind turbines are introduced into migratory bird paths or other environments. While the literature could be more complete regarding the documentation of negative effects on birds and bird habitats during the planning, construction, and operation of wind power projects, there is sufficient evidence to raise concerns. Authoritative and mandatory vigilance monitoring and long-term surveillance over the life of the industrial wind facility are lacking. By the (...) time the documentation of the rate of bird kills, including that of endangered species is available in an environs of an industrial wind turbine facility, the damage may be irreversible. This article briefly explores the negative environmental impacts of the siting of industrial wind turbines and associated infrastructure, including transformer stations and transmission lines, in proximity to migratory bird corridors, wetlands, and nesting grounds. Research is required prior to proceeding with further industrial wind development in these environs. The authors propose that there is sufficient scientific evidence to require invoking the precautionary principle and halting further development until these risks are resolved. (shrink)

In this study, a hybrid model based on intelligent techniques is developed to predict the active power generated in a bioclimatic house by a low power wind turbine. Contrary to other researches that predict the generated power taking into account the speed and the direction of the wind, the model developed in this paper only uses the speed of the wind, measured mainly in a weather station from the government meteorological agency (MeteoGalicia). The wind speed (...) is measured at different heights, against the usual measurements in others researches, which uses the wind speed and the direction measured in a weather station on the wind turbine nacelle. The prediction is performed 30 minutes ahead, what ensures that the Building Management System knows the energy generated by the low power wind turbine 30 minutes before, and it can adapt the consumption of different equipment in the house to optimize the power use. The main objective is to allow the Building Management System to optimize the uses of energy, taking into account the predicted amount of energy that will be produced and the energy consumed in the house. The developed model uses a hybrid topology with four clusters to improve the prediction, achieving an error lower than 6.5% for Mean Absolute Error measured in a final test. To perform this test, part of the original dataset was isolated from the beginning of the training process to check the model with a dataset that is not used before, simulating the model as it is receiving new data.

The Canadian residential sector contributes approximately 80 megatons of GHGs to the environment yearly. With the ratification of Kyoto Protocol, Canada has committed to reduce its 1990 GHG emission levels by at least 5% between 2008 and 2012. To meet this target, Canada must evaluate and exploit all feasible means to reduce fossil fuel energy consumption and GHG emissions. Test-case Canadian houses were modeled in the building-energy simulation software ESP-r. Requisite housing stock data were extracted from Canada's residential end-use energy (...) surveys. Photovoltaic and wind-turbine energy systems were assessed for their contribution to electricity generation and GHG savings. Typical household electrical consumption versus renewable electricity generation was assessed to estimate the GHG reduction, cost saving in electricity, and the impact of these technologies on single detached houses. With the use of net-metering, 100% of electricity requirements can be met by these technologies in certain cases, resulting in significant reductions in GHG emissions. (shrink)

As more wind energy projects are constructed and placed into operation, their potential downsides are becoming more apparent to a larger number of people. One of the most contentious issues is that of the potential loss of property values for those who happen to own homes close to these projects. This issue may be more parochial and therefore seemingly less important than larger global issues, such as energy independence, sustainability, or global warming. But for those most directly affected by (...) these projects, it can serve as a single proxy for all the other local concerns with wind turbines, such as noise, visual pollution, and health. Moreover, rural homeowners vote in high numbers, and in those locations where there is still local control of wind energy projects, the local politicians will eventually reflect those concerns. The wind energy industry counters these concerns by quoting from a series of industry and government studies that claim to show that proximity to wind turbines does not materially affect home prices. However, their efforts at allaying the concerns of the local homeowners have not been very successful. This article discusses some of the reasons why the industry has been unsuccessful at quelling these concerns, including an evaluation of the evidence from both sides of the wind energy debate as a homeowner might see it and ends with suggestions on how the industry might allay these concerns.

The use of energy from wind has a multi-faceted relationship to visibility. Between 1973 and 1991, various actors in the West German environmental movement made assertions about the visibility of renewable sources of power, but wind energy took on a particular prominence. In this article, the question of how different actors have used knowledge and the materiality of wind turbines for competing purposes is explored. Environmentalists attempted to create visible signs of a valid alternative energy future by (...) tinkering with small, decentralized wind turbines, while the Federal Republic of Germany's Ministry of Research and established energy providers used the failure of the state-subsidized large-scale wind-energy project GROWIAN to criticize renewables and brand their application as misguided. In both cases, actors created new wind energy visibilities to convey their conflicting interests—pitting those advocating a new, environmentally friendly energy system against those who sought consolidation of the large-scale fossil-nuclear energy system.

Despite the fact that they are in most respects environmentally benign, electricity-generating wind turbines frequently encounter a great deal of resistance. Much of this resistance is aesthetic in character; wind turbines somehow do not "fit" in the landscape. On one (classical) view, landscapes are beautiful to the extent that they are "scenic," well-balanced compositions. But wind turbines introduce a discordant note, they are out of "scale." On another (ecological) view, landscapes are beautiful if their various elements form (...) a stable and integrated organic whole. But wind turbines are difficult to integrate into the biotic community; at least in certain respects, they are like "weeds." Moreover, there is a reason why the 100-meter, three bladed wind turbines now favored by the industry cannot very well be accommodated to any landscape view. They are, as Albert Borgmann would put it, characteristic of contemporary technology, distanced "devices" for the production of a commodity rather than "things" with which one can engage. It follows that the only way in which the aesthetic resistance to wind turbines can be overcome is to make them more "thing-like." One such "thing-like" turbine is discussed. (shrink)

The purpose of this article is to investigate wind turbine production, the variability of that production, and the relationship between output and system-wide demand. A review of the literature reveals that a variety of measures (and methods) to explore the variability of wind power production exist. Attention then turns to the province of Ontario (Canada), and the performances of four wind farms are examined for 2006 and 2007. Key conclusions include that the wind farms' capacity (...) factors vary from 27.6% to 35.6%, with higher values in winter as compared to summer; wind power performs better than the seasonal average during peak periods; wind is a better “partner” for the Ontario electricity system in the winter as opposed to the summer; and the increased geographic distribution of wind farms decreases their collective variability.

This paper traces the origins of two technological trajectories in the contemporary history of wind power technology: the American Smith-Putnam Wind Turbine and the Danish Gedser Wind Turbine. Describing the two wind turbine projects in terms of their technical design characteristics, the professional background of the individuals involved, the organizational features of the technological knowledge production, and the historical context, the paper builds on the notion of technological trajectories in the making as a (...) means of identifying emerging selection mechanisms for possible engineering problem solutions, scientific methods, material artifacts, and financial assessment techniques. Conceived during the Great Depression and World War II, respectively, both projects promoted the idea that wind power could make a cost-effective contribution to the existing electric utility system. The two projects resulted in distinctive wind turbine innovations that paved the way for two technological trajectories in the contemporary history of wind power. Studying the emergence of technological trajectories, it is argued, requires the historian of technology to attend to well-known features of technological design and its cultural context that in retrospect appear to be significant, but also to tackle the creation of novelty and the inevitability of technological uncertainties about which the logic of trajectories has little to say.

Wind turbine noise is annoying and has been linked to increased levels of psychological distress, stress, difficulty falling asleep, and sleep interruption. For these reasons, there is a need for competently designed noise standards to safeguard community health and well-being. The authors identify key considerations for the development of wind turbine noise standards, which emphasize a more social and humanistic approach to the assessment of new energy technologies in society.

In 1975, the death of dictator Francisco Franco opened the door to a turbulent period known as the “Spanish Transition.” In the wake of the 1973 oil crisis, national politics, political violence and social demands were interwoven with international shifts in science and technology and global debates on “energy transitions.” In close dialogue with foreign environmental groups, the anti-nuclear movement in Spain deployed a large repertoire of collective action; it ranged from pleasant activities to violent direct actions against nuclear technologies, (...) but also included the making of technological alternatives. Counter-culture activists and counter-experts opposed nuclear energy and promoted renewable energy as two sides of the same coin.This paper explores the pioneering initiatives of an anarchist-oriented group called Self-Managed Radical Alternative Technologies, created in 1976, and a group of young engineers who founded the cooperative Ecotècnia, which was behind the construction of the first commercial wind turbine in Catalonia in 1984. The paper focuses on the transnational circulation of grassroots knowledge, the epistemics of resistance, and the development of wind energy technologies as “technologies of protest.” Technologies of protest illuminate how the social construction of technology is intertwined with what I call the “social destruction of technology.”.

In this paper, an active frequency control strategy of wind turbines based on model predictive control is proposed by using the power margin of wind turbines operating in load shedding mode. The frequency response model of the microgrid system with the load shedding of the wind turbines is used to predict the output power and system frequency deviation of the wind turbine. According to the prediction information, the output power control signal of the model predictive (...) controller in the wind turbine can be optimized. On this basis, a wind turbine active participation frequency control strategy based on model predictive control is designed by rolling prediction and optimization. The wind turbine power control signal after the strategy is used to adjust the output power of the wind turbine and balance the change of the active power of the system to reduce the frequency deviation.

The income and careers that come with building wind turbines have become a lifeline for many factory towns and farming communities. Generating electricity from the wind puts increasingly cheap power on the grid, saving consumers billions a year. And it is one of the biggest, fastest, cheapest ways to reduce carbon pollution, reducing the threat of climate change. Yet as wind farms have rapidly spread to forty‐one states, their developers must make their case anew with each community (...) that hosts them. Facts matter, but so do empathy, honoring deep connections to neighbors and landscape, and developing mutual respect. Successful wind farm developers listen first for shared values and speak with inclusive language, to communicate with potential opponents across divides of misunderstanding and motivate local residents to adapt to and benefit from change.

This work presents a distributed generation system that combines system of a wind turbine and photovoltaic using a unified power quality conditioner. Along with providing active power to the utility grid, Wind-PV-UPQC improves PQ indicators, for example, voltage drops/surges, harmonics of grid voltages, and PF. Since Wind-PV-UPQC depends on dual compensation scheme, the parallel converter works as a sinusoidal voltage source, while the series converter works as a sinusoidal current source. In this way, a smooth transition (...) from grid operation to island operation and vice versa can be achieved without load voltage transitions. In addition, in order to overcome the problems through abrupt solar radiation or wind speed variations, a faster power balance is achieved between the wind turbines, the PV array, and the grid, as FFCL pursue the production of the current references of series converter. Consequently, the dynamic reactions of the converter currents and the voltage of dc bus are enhanced. A comprehensive analysis of flow of the AP through the converters is done to ensure a proper understanding of how Wind-PV-UPQC works. Finally, the simulation results are shown to estimate the dynamic and static performance of Wind-PV-UPQC in conjunction with the power distribution system. (shrink)

This article investigates the impacts of proper modeling of the wake effects and wind speed delays, between different wind turbines' rows, on the dynamic performance accuracy of the wind farms models. Three different modeling scenarios were compared to highlight the impacts of wake effects and wind speed time-delay models. In the first scenario, wind wake effect and time delay are ignored. Consequently, all wind turbines are assumed subjected to the same wind speed profile. (...) The second scenario considers the wind wake effect, and it was modeled by reducing the incident wind speed values by 0.5 m/s from one row to the next row facing the wind. The last scenario, the proposed model, used the wind wake effect model developed for wind turbines micrositting applications and considered the effect of the delay time between the wind speed profiles incident on the different wind turbines' rows.

Ultra-short-term wind speed prediction can assist the operation and scheduling of wind turbines in the short term and further reduce the adverse effects of wind power integration. However, as wind is irregular, nonlinear, and nonstationary, to accurately predict wind speed is a difficult task. To this end, researchers have made many attempts; however, they often use only point forecasting or interval forecasting, resulting in imperfect prediction results. Therefore, in this paper, we developed a prediction system (...) integrating an advanced data preprocessing strategy, a novel optimization model, and multiple prediction algorithms. This combined forecasting system can overcome the inherent disadvantages of the traditional forecasting methods and further improve the prediction performance. To test the effectiveness of the forecasting system, the 10-min and one-hour wind speed sequences from the Sotavento wind farm in Spain were applied for conducting comparison experiments. The results of both the interval forecasting and point forecasting indicated that, in terms of the forecasting capability and stability, the proposed system was better than the compared models. Therefore, because of the minimum prediction error and excellent generalization ability, we consider this forecasting system to be an effective tool to assist smart grid programming. (shrink)

Abstract:In Scotland, policies supporting the development of wind farms frequently come into conflict with those designed to protect wild land. The siting of turbines is, amongst other things, administered by wild land areas, whilst wild land areas are, in part, characterized by the absence of turbines. In this article, I focus on how the classification of wild land has been constructed in official narratives and I describe the substantial scale of collaborative human labor implicated in this process. I draw (...) on the story of a public local inquiry into a wind farm proposal to make visible some of the contradictions implicit in the term's use and to argue that wildness, as conceived by Scottish Government, is primarily an aesthetic category which relies on absences. I argue that employing wild land as an administrative technology conceals the various kinds of labor that are intrinsic to creating wild land. The work of extending and reinforcing the technologies which govern land use is hidden behind the notion of wild land as a place from which human exertions and technologies are absent. (shrink)

Social licence to operate (SLO) is the ongoing acceptance or approval for a development that is granted by the local community and other stakeholders. From the current media and political attention on Australian wind farms, it appears that many specific wind farms, or indeed the industry as a whole, may not hold an SLO with affected stakeholders. This research was undertaken to examine whether the SLO might be a useful framework to enhance engagement and increase societal understanding of (...) wind farms. Twenty-seven interviews across nine wind farms were conducted with stakeholders representing wind companies, local government authorities, local opposition, local support and turbine hosts. The interviews revealed a complexity of concerns that informed the stakeholders’ perspectives, including “game-changing” issues that may stand to significantly increase wind farm acceptance. The results are presented with practical steps towards the development of a preliminary working model of an SLO for Australian wind f.. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:134 When the woman saw that the fruit of the tree was good for food and pleasing to the eye, and also desirable for gaining wisdom, she took some and ate it —­Genesis 3:6 Abstract Aesthetics has emerged as an important battleground in the moral quest for a lower carbon society. Especially in the case of proposed wind farms (an environmentally benign technology in terms of low carbon (...) emissions), opponents frequently refer to the unsightly machines creating negative landscape impacts and ruining the view. This essay seeks to reflect on the particular ways in which visual aesthetics are framed and mobilized in this moral debate. Exploring the dividing lines between pictoral and more-­ than-­ representational approaches I ask if the moral dilemmas in our landscape decisions (e.g. individual rights to beauty or collective duties toward future generations) are obscured by physical or visual realms. The largely invisible nature of wind, electricity and climate change, set within the physical and tangible nature of landscapes and turbines, challenges us to experience the aesthetics of landscapes-­ with-­ machines through more creative and engaging means that are not limited to visibility, nor deaf to morality. SIN, DUTY, AND THE AESTHETICS OF NATURE As the first act of sin in the bible, Eve’s consumption of a visually aesthetic fruit led to humans being banned from the Garden of Eden. Looking at the above sentence more closely, we could even argue that “good for food” is not a positive condition (e.g. tasty, nourishing), but Justice in the Eye of the Beholder? ‘Looking’ Beyond the Visual Aesthetics of Wind Machines in a Post-­Productivist Landscape DAN VAN DER HORST Dan van der Horst / Justice in the Eye of the Beholder? 135 rather the absence of a negative (e.g. inedible), whilst “also desirable” may sound like the hunger for wisdom was only a secondary, additional attraction. The sentence thus draws attention to the key role of aesthetics in the making of a moral decision; would Eve have eaten the forbidden fruit if it was not “pleasing for the eye”? Aesthetic judgments may be informed by a range of factors, but as this bible quote illustrates, morality is key among them. Associations between right and wrong on the one side and beauty or ugliness on the other, are not exactly rare in written history, be they religious, literary or scholastic works. As a marked contribution to the latter, Immanuel Kant has paid particularly close attention to the links between aesthetics and morality, arguing amongst others that any universal agreement in judgments of the sublime must rest on an appeal to moral feelings.1 But universality is not the only logical link between aesthetic judgementandmorality.Peoplecanfeelasenseof‘duty’tofindcertainthings beautiful e.g. because that is the aesthetic judgment of the group they aspire to belong to.2 Whilst this sense of duty can refer to social conditioning and group belonging, it also has resonance for landscape aesthetics at a time of anthropogenic climate change (a universal threat) when we must “learn to love the low carbon landscape.”3 This presents a point of departure from the debate on the moral obligation of preserving aesthetically pleasing landscapes (as we tend to do through legal designations, e.g. national parks), an ethical logic which leads, to use the words of Holmes Rolston, “from beauty to duty.”4 Moreover a posi­ tive aesthetical appreciation of a landscape because it accommodates low carbon technologies, would potentially require an inverse ethical logic, i.e. from duty to beauty.5 Notwithstanding the clear conceptual links between moral and aesthetic judgment, in everyday life it may be far less clear what kind of moral issues may underpin particular expressions of aesthetic sensibility. This can be particularly problematic for the deployment of environmental technologies (i.e. technologies pursued to reduce pollution ) that have significant landscape footprints. That is where we can find universal moral claims demanding environmental action for the common good rubbing up against aesthetic landscape judgments in places where such developments are proposed. This produces an unsatisfactory situation in which the deployment of clean technologies ENVIRONMENT, SPACE, PLACE / VOLUME 10 / ISSUE 1 / 2018 136 is delayed, tensions within local communities may increase...

Scientists and engineers often are not much interested in theoretical-ethics discussions. Frequently, like Harvard’s Cass Sunstein (2002), they propose “freemarket environmentalism,” basing environmental decisions on cost-benefit analysis and on saving the greatest number of lives for the fewest number of dollars. They say that when society overregulates, by emotively and irrationally rejecting environmental-risk decisions based only on cost-benefit analysis (CBA), it reduces manufacturing jobs, shrinks the economic pie, makes people poorer, and thus causes unnecessary deaths. To avoid these economic (...) problems—that harm everyone—Sunstein (2002, ix, 7) and others argue “for a kind of cost-benefit state” that .. (shrink)

Does the establishment of a permanent InternationalWar Crimes Tribunal (International Criminal Court - ICC) constitute a challenge to national sovereignty? According to previous US governments and several American observers, the answer is yes. Establishing a world court that acts independently of the states that gave birth to it renders the idea of sovereignty meaningless. This article analyzes the American objections to the ICC and the conception of sovereignty and international law underlying these objections. It first considers the structure and intent (...) behind the criminal court and attempts to unveil the logic hiding behind the idea of ‘America’s historical uniqueness.’ It touches on the diverging US and European conceptions of sovereignty and ends up arguing that governments that stick to traditional conceptions of sovereignty and international law in the employment of their foreign policy may lose the moral legitimacy that has proven increasingly important for winning the sympathy of allies and regaining world leadership.
