Energy consumption has always a noticeable impact on the environment. Fast growing world population, increasing prosperity and the hunger for fuel that has developed a consequence, have led to a rapid rise in the need for energy, so to fulfill that need we require renewable resources. The non-conventional or alternative energy resources are not amenable to depletion even with irrational levels ...
Beyond energy efficiency in evaluating sustainable development in planning and the built environment
The EU has set the policy target of reducing energy use by 20% by the year 2020. Therefore, a substantial consumption decrease is needed in built environment sector. Despite the great energy efficiency improvements in households, recent energy consumption data analyses show that these targets will unlikely be reached. The general aim of this study is to point out the need to define new indicato...
انرژی هستهای یکی از منابعی است که نقش عمدهای در تولید برق ایفا میکند. تحلیل روند سطح تقاضا و منابع عرضهی انرژی در جهان، توجه به روند تهی شدن منابع فسیلی در دهههای آینده و مزیتهای زیستمحیطی انرژی اتمی، از عواملی هستند که سبب شدهاند تا انرژی هستهای یکی از حاملهای قابلدسترس و مطمئن انرژی در جهان به شمار رود. از این رو بررسی تأثیرات انرژی هستهای بر رشد اقتصادی به منظور درک دلیل سرمایهگ...
thin layer drying of russian olive (elaeagnusan gastifolial l.) fruit using a hot air dryer in order to calculate effective moisture diffusivity, activation energy and energy consumption has been evaluated in this article. the selected variables included three levels of air velocity of 0.5, 1 and 1.5 m/s and three air temperature levels of 50, 60 and 70°c. increased air temperature increased ef...
Cloud Computing is an internet based computing which makes and different types of services available to users. For customers based on their required services over the internet virtualized resources are provided. The fast growth of cloud resources with customers demand increases the energy consumption results in carbon dioxide emission. However, energy consumption and carbon dioxide emission in ...
the quest for power has formed much of the world history especially in 20th and 21st centuries. oil (energy) particularly after industrial revolution has been a tool for conquest and power and has been transformed to a geopolitical issue. from a geopolitical point of view this has been the case for the last two centuries in central asia and caucasus. central asia and caucasus has always been...
Smart homes with zero energy as an option to combine a large number of distributed energy resources to power networks in building a new future designs, are used. Zero energy homes equipped with smart power integrated production and consumption of zero over a year. In this study is that the sources of energy supply management program for a zero-energy home using mixed integer programming techniq...

The main aim of this paper is to evaluate the energy efficiency in 30 provinces of Iran by applying the different methods of DEA and Anderson and Peterson during the period of 2009-2013. Also, since classical analysis models do not differentiate efficient cases, the AP method (Anderson-Peterson) was used to rank efficient units for evaluating efficiency correctly. So that combination of input v...
