The expansion of wind turbines plays a significant role in developing the ability of a country like Sweden to achieve climate-neutral energy production without relying on nuclear power plants. Wind-turbine energy production is expected to grow in the coming decades. Conflicts may arise between, on the one hand, the government and the energy authority, and, on the other hand, municipalities and property owners, especially if this expansion affects other economic activities, such as tourism and reindeer husbandry, or property values. This report aims to analyse the negative capitalization of wind turbines on property values in Sweden over the last ten years. Our conclusions clearly show a relatively significant capitalization and that this capitalization is relatively local, within eight kilometers of the wind power plant. Large wind turbines, or larger clusters of wind turbines in wind farms, impose a greater socio-economic cost on lower value properties.

This paper examines the effect of different wind turbine classes on the electricity production of wind farms in two areas of Cyprus Island, which present low and medium wind potentials: Xylofagou and Limassol. Wind turbine classes determine the suitability of installing a wind turbine in a particulate site. Wind turbine data from five different manufacturers have been used. For each manufacturer, two wind turbines with identical rated power (in the range of 1.5 MW–3 MW) and different wind turbine classes (IEC II and IEC III) are compared. The results show the superiority of wind turbines that are designed for lower wind speeds (IEC III class) in both locations, in terms of energy production. This improvement is higher for the location with the lower wind potential and starts from 7%, while it can reach more than 50%.

The multi-criteria evaluation methods of complex systems such as the new and renewable technologies gradually spring up. The feasibility of energy power plants is evaluated and considered from many aspects, such as technology, economic cost and environment protection. However, the energy power plants’ ranking results in different methods or different weighs can be different. Accordingly, the sequencing results should be aggregated and analyzed, and then an integrated result should be given out. Aiming to get the specific evaluation result, 10 kinds of energy power plants, such as hydro, nuclear, wind, geothermal and biomass plants are considered and evaluated. The singular value decomposition method is employed to aggregate the evaluation results in grey relational method, PROMENTHEE II method, and other results from literature. The integrated evaluation result shows that the hydro and nuclear power plants are located on the first place and the renewable energy power plants have great potential development in the future.

Abstract As a renewable, unlimited and free resource, wind energy has been intensively deployed in the past to generate electricity. However, the maintenance of Wind Turbines (WTs) can be challengeable. On the one hand, most wind farms operate in remote areas and on the other hand, the dimension of WTs’ tip/hub/rotor are usually enormous. In order to prevent abrupt breakdowns of WTs, a number of Condition Monitoring (CM) methods have been proposed. Focusing on bearing diagnostics, Squared Envelope Spectrum is one of the most common techniques. Moreover in order to identify the optimum demodulation frequency band, fast Kurtogram, Infogram and Sparsogram are nowadays popular tools evaluating respectively the Kurtosis, the Negentropy and the Sparsity. The analysis of WTs usually requires high effort due to the complexity of the drivetrain and the varying operating conditions and therefore there is still need for research on effective and reliable CM techniques for WT monitoring. Thus the purpose of this paper is to investigate a blind and effective CM approach based on the Scattering Transform. Through the comparison with state of the art techniques, the proposed methodology is found more powerful to detect a fault on six validated WT datasets.

There is not a common attitude in a society for socio-scientific issues (SSI) such as whether to use nuclear power plants for energy production. Within this respect, the aim of the research is to examine pre-service science teachers’ and pre-service social studies teachers’ attitudes toward SSI and to reveal their views about setting up nuclear power plants in their country. The participant of research is 120 pre-service teachers. Firstly, Attitudes toward Socio-scientific Issues Scale (ATSIS) was implemented and then, focus group discussions were done with five students from each department separately so as to understand their views about nuclear power plants. Findings revealed that whereas pre-service teachers are eager to learn more about SSI, they have anxiety about it due to religion, moral and ethical perspectives. In addition, whereas both groups of pre-service teachers have some common views about nuclear power plants, pre-service science teachers do not have more positive views about having nuclear power plants in their country. Key words: attitude towards socio-scientific issues, focus group discussion, pre-service teachers, nuclear energy.

Real Estate Prices

PurposeOklahoma has seen rapid growth in the development of wind energy over the past decade. Residents are concerned about the negative impacts of turbines such as noise or their appearance. This has raised concerns about property values. Thus, this paper aims to examine and quantify the overall impact of wind turbines upon real estate prices in Western Oklahoma.Design/methodology/approachSales prices and the history of approximately 23,000 residential real estate records for both platted and unplatted properties in five counties were examined prior to the announcement of construction, after announcement and after construction. A hedonic analysis was undertaken to examine the real estate prices of the properties near wind farms.FindingsWhile there may be isolated instances of lower property values for homes near wind turbines, results show no significant decreases in property values over homes near wind farms in the study area. Similar results are found for the unplatted properties.Practical implicationsThis paper highlights that in spite of mixed attitudes toward wind farms and misconceptions regarding the link between turbines and property values, Oklahoma’s growing wind industry can continue to thrive without negatively impacting nearby home and land values and prices.Originality/valueAlthough there have been numerous studies examining the relationship between wind turbine locations and real estate prices, no study has combined the large quantity of records (over 23,000) as well as both platted and unplatted locations.

Based on data from 1162 wind turbines, with a rated power of at least 1.8 MW, installed in Sweden after 2005, the accuracy of the annual energy production (AEP) predictions from the project planning phases has been compared to the wind-index-corrected production. Both the production and the predicted AEP data come from the database Vindstat, which collects information directly from wind turbine owners. The mean error was 7.1%, which means that, overall, the predicted AEP has been overestimated. The overestimation was higher for wind turbines situated in open terrain than in forest areas and was higher overall than that previously established for the British Isles and South Africa. Dividing the result over the installation year, the improvement which had been expected due to the continuous refinement of the methods and better data availability, was not observed over time. The major uncertainty comes from the predicted AEP as reported by wind turbine owners to the Vindstat database, which, for some cases, might not come from the wind energy calculation from the planning phase (i.e., the P50-value).

There has been a rapid growth in construction activities during the last few decades owing to overall development in all facets of humanity. Due to technological advancements and ever increasing civilization, there is a persistent need of energy. Along with the conventional energy sources, the renewable energy sources have also significantly contributed to the rising energy needs. As a renewable source of energy, numerous small hydro-power plants (SHPPs) have been built up across the world in the recent past. Usually these SHPPs are being built and operated by the private developers complying with the government regulations. In order to assist a developer in selecting the most profitable and feasible SHPP for construction and subsequent operation, a method based on fuzzy axiomatic design principles is employed in this paper. The techno-commercial and socioeconomic criteria as considered for analyzing the feasibility of the candidate SHPPs are expressed qualitatively using trapezoidal fuzzy numbers. The performance of each SHPP is evaluated in terms of its total information content and the one with the least information content is selected to be the best venture for the required construction activity. The adopted methodology is found to have immense potential to the developers while selecting the most feasible project for construction.

British Home

For over half a century, from 1924 to 1986, the Electrical Association for Women (EAW) worked to modernize the British home by bringing the blessings of labour-saving appliances to the aid of British women. Adopting a strategy of facilitation, the EAW sought, on the one hand, to educate women about electricity and its advantages in the home, encourage them to demand greater access to that electricity and keep them abreast of new developments in appliances and the infrastructure (from a national grid to sufficient outlets) necessary for enjoying them. On the other hand, the organization sought to discover the real needs and desires of the women themselves, and to bring this forcibly to the attention of the electrical industry in Great Britain ; to make the ‘women's point of view’, as it was called, a factor in the production, distribution and application of electricity in the home.Although the very masculine electrical industry was a decisive part of both the EAW's context, and of its financial and advisory structure, the group proudly insisted that it was a women's organization in which women addressed other women about women's concerns and well-being. In its early years, the excitement of women coming together in a modern cause was palpable, but as the leadership aged and electricity turned from modern vision to commonplace reality, the almost religious zeal and pace of activities began to falter. A late-hour attempt to highlight nuclear power plants as evidence of a renewed and equally exciting modern moment fell short, and in 1986 the EAW quietly dissolved itself, the casualty of large social changes, some of which it had proudly helped to bring about.

Abstract Energy production by wind turbines has many advantages. The wind is a renewable energy that does not emit greenhouse gases and has caused a considerable increase in wind farms around the world. However, this type of energy is not completely free of impact. In particular, wind turbines displace and kill a wide variety of wild species what forces us to plan their location well. In any case, the determination of the effects of wind farms on fauna, especially the flying one, is difficult to determine and depends on several factors. In this work, we will try to establish a mathematical algorithm that allows us to combine all variables that affect the species with the idea of quantifying the effect that can cause the installation of a wind farm with certain characteristics in a given place. We have considered specific parameters of wind farms, the most relevant environmental characteristics related to the location of the wind farm, and morphological, ethological and legal characteristics in the species. Two types of assessment are established for the definitive valuation. Total Assessment and Weighted Assessment. Total Valuation is established based on a reference scale that will allow us to establish categories of affection for the different species while Weighted valuation allows us to establish which species are most affected.

In the last 20 years in the Russian society and in the government there are discussions on the need to "get off the oil needle." The situation in the Russian economy dictates measures to further diversify exports, based on the export of "high technology". This article describes the history of the company, which for the past two decades has survived in a very difficult situation and, practically without the help of the state, has found new partners who want to order the construction of nuclear power plants in their country. It must be borne in mind that when building a nuclear power plant abroad, a basis is created for long-term economic cooperation between Russia and other countries, which makes it possible to implement with high efficiency a large volume of related services, such as: • transfer of licenses and know-how, design and survey works, supply of complete equipment and spare parts, engineering consulting services; • provides employment of the population within the country (about 300 enterprises and tens of thousands of employees participate in the NPP project abroad as subcontractors); • increases the availability of regional budgets; • increases globally the competitiveness of Russian equipment in particular and Russian high technologies in general.
