In recent years, optimal use of fossil fuels, reduction of environmental pollution and exploitation of renewable energy is one of the most important issues in the policies of different countries, and as you know, Iranchr('39')s electricity industry is dependent on fossil fuel consumption strongly, which causes environmental pollution. The aim of this study is to obtain the optimal combination o...

The benefits of wind power generation have led to an ever-increasing expansion of wind farms around the world. The low cost of production and the environmental benefits of wind farms are some of the main reasons for using wind energy. On the other hand, uncertainty costs in the production and control of the output of wind turbines are among the problems that are being encountered for electricit...
One of the greatest challenges of renewable resources is unpredictable nature of these resources. Nevertheless use of fossil-renewable integrated hybrid system, which uses some renewable resources rather than a single source, for the supply of power, is the most affordable and the most reliable method. In this study by use of analytical programming approach and 2012 base year statistics, produc...
Background and purpose: Energy recovery from waste is an appropriate method for waste management and energy production from food waste. Energy production through waste incineration produces significant emission which is a critical threat for environment. Anaerobic digestion of the waste is a suitable way to produce clean energy. This study aimed to investigate the anaerobic digestion from food ...
In this research, solar-drived integrated Hydrogen production (HP) using high-temperature steam electrolysis (HTSE) is thermodynamically evaluated. This system includes an organic Rankine cycle (ORC), Rankine cycle, Brayton cycle, solar tower, and High Temperature Steam Electrolysis (HTSE). Solar energy supplies thermal energy. This heat source is applied for generating power. This energy is us...
Using Photovoltaic systems is gradually expanded by increasing energy demand. Abundance and availability of this energy, has turned to one of the most important sources of renewable energy. Unfortunately, photovoltaic systems have two big problems: first, those have very low energy conversion efficiency (in act between 12 and 42 percent under certain circumstances). Second, the power produced b...
production of electricity for promotion of people’s welfares is inevitable.there are about 54000 mw of various power plants in iran. the type of power plants includes gas, steam, combined, hydro and a very minute amount of wind mills. the per capita electricity production is about 2200 kwh. power plants can impose adverse environmental impacts during construction and utilization phases. envir...
The purpose of this study is to evaluate electricity consumption over the business cycles of industrial production of Iran from1967 to 2013. In this paper, the existence of co-integration between electricity consumption and industrial production is checked using ARDL approach; furthermore, causal relationship between electricity consumption and industrial production is investigated. The finding...
Strains with 1-aminocyclopropane-1-carboxylate (ACC) deaminase activity can cause plant growth on stress condition. In the presence of bacteria with the ability of ACC deaminase production in the rhizosphere, it is possible to convert the ethylene precursor (ACC) to α-ketobutyrate and ammonium, reducing the ethylene levels in host plants. In order to measure the power and level of A...
