In this article, grey based theory is used to grasp the ambiguity exists in the utilized information and the fuzziness appears in the human judgments and preferences. Grey theory can produce satisfactory results, and hence stimulates creativity and the invention for developing new methods and alternative approaches. This article is a very useful source of information for fuzzy grey and decision making using more than one decision makers in fuzzy environment. A case study on system selection comprised of 12 attributes and 7 alternatives is constructed and solved by the proposed method and the results are compared with the results obtained from QSPM, TOPSIS and SAW approaches for analysis purposes. © 2013 Elsevier B.V.

In this paper, an adaptation of MIP, GA, SA, and TS to network planning under the carbon emission trading program is described and computational results are given. As will be shown, the results are very encouraging. The cost function of this problem consists of the capital investment cost in discrete form, the cost of transmission losses, the power generation costs and carbon emission costs. The optimization model has the ability to minimize the total costs and provides the best solutions, which are both cost-effective and environmentally friendly. This method of solution is demonstrated on the real problem. Finally, the performance of the proposed procedure is compared with that of the most well-known as mixed-integer programming. © 2010 Elsevier Ltd.

Renewable energy sources are expected to have a flourishing future and an important role in many countries as well as Iran. The purpose of this study is to offer economic evaluation of small wind turbine installation for city of Kerman in southeastern part of Iran. A long term data source, consisting of 14 years (1991-2004) of three-hourly mean wind data, was adopted and analyzed. Mean wind power based on measured data and Weibull distribution function as well as the relative percentage error (RPE) between obtained values of wind power based on two methods have been studied. It was found that Weibull distribution was unsuitable for this study. Based on these data, it was found that the numerical values of the shape and scale parameters for Kerman varied over a wide range. Annual values of "k" ranged from 1.266 to 1.473 with a mean value of 1.375, while annual values of "c" were in the range of 2.504-3.478 with a mean value of 3.000 m/s. The annual mean wind speed of the city is obtained as 2.743 m/s at 10 m height. Wind power densities have been estimated and relatively low for large wind turbines. This paper analyses economic evaluation and applications of three small wind turbines. The results show that Kerman has an available wind energy potential in order to install some small wind turbine models for the sustainable development of Kerman. © 2013 Elsevier Ltd.

The use of wind energy reduces CO2 emission and increases new employment opportunities. The positive impacts of wind energy on the mitigation of climate change as well as opportunity to diminish energy dependency are indisputable. Wind energy helps decreasing import dependency, diversifying sources of production, and contributes to a sustainable development in many countries. This article explores the importance of global wind turbine development and other relevant issues which are important. In this energy scenario, global installed wind turbines, energy potential and employment issues were discussed. Wind energy deployment creates a significant number of jobs, and does so at a time when other energy sectors are shrinking. Global wind turbine installation for recent years (2006-2008) was thoroughly discussed along with employment issues regarding wind industry in the world. The wind energy sector has grown exponentially since the end of the 1990s, especially within many countries, and this has affected the employment levels of countries involved. © 2009 Elsevier Ltd.

This paper analyses the wind speed of some major cities in province of Yazd which is located in central part of Iran. Also, the feasibility study of implementing wind turbines to take advantage of wind power is reviewed and then the subject of wind speed and wind potential at different stations is considered. This paper utilized wind speed data over a period of almost 13 years between 1992 and 2005 from 11 stations, to assess the wind power potential at these sites. In this paper, the hourly measured wind speed data at 10 m, 20 m and 40 m height for Yazd province have been statically analyzed to determine the potential of wind power generation. Extrapolation of the 10 m data, using the Power Law, has been used to determine the wind data at heights of 20 m and 40 m. The results showed that most of the stations have annual average wind speed of less than 4.5 m/s which is considered as unacceptable for installation of the wind turbines. City of Herat has higher wind energy potential with annual wind speed average of 5.05 m/s and 6.86 m/s, respectively, at height of 10 m and 40 m above ground level (AGL). This site is a good candidate for remote area wind energy applications. But some more information is required, because the collected data for Herat is only for 2004. Cities of Aghda with 3.96 m/s, Gariz with 3.95 m/s, and Maybod with 3.83 m/s annual wind speed average at height of 10 m above ground level are also able to harness wind by installing small wind turbines. The Tabas and Bafgh sites wind speed data indicated that the two sites have lower annual wind speed averages between 1.56 m/s and 2.22 m/s at 10 m height. The monthly and annual wind speeds at different heights have been studied to ensure optimum selection of wind turbine installation for different stations in Yazd. © 2009 Elsevier Ltd.
