Among the different forms of clean energies, solar energy has attracted a lot of attention because it is not only sustainable, but also is renewable and this means that we will never run out of it but the potential of using this form of renewable energy depends on its accessibility. Due to the...

In this paper, Data Envelopment Analysis (DEA) technique was applied for apple (Red and Golden delicious varieties) producers in West Azarbaijan province, Iran (2008-2009). Results showed that the highest share of energy consumption belongs to packaging (57%) and irrigation (16%). Highest share...

This study was conducted in the 2008-9 production year in West Azerbaijan province (Uromia Township). The Energy Ratio, Energy Productivity, Economic Productivity and Mechanization Index were estimated for apple production. Data were collected using random sampling for 80 face-to-face...

Finding energy sources to satisfy the world's growing demand is one of society's foremost challenges for the next half-century. The challenge in converting sunlight to electricity via photovoltaic solar cells is dramatically reducing $/watt of delivered solar electricity. In this context the sun...

In this study data from 17 years (1990-2006) were collected to determine energy intensive areas and evaluate energy parameters of Iran's agronomy sector. All the direct and indirect inputs of energy for the production of 19 agricultural commodities were evaluated. The inputs and outputs were...

This study is dedicated to the assessment of the possibility of replacing fossil fuels with renewable energy as a source of power in modern agriculture. We examined the use of a completely sustainable agricultural mechanization system based on a renewable energy system and a battery powered,...

This paper examines the energy use patterns and relationship between energy input and yield for grape production in Malayer region of Hamadan Province. Data from 50 farmers were collected using a face-to-face questionnaire method. In the surveyed vineyards, average yield and energy consumption...

This study evaluated the energy balance and economic analysis between inputs and output of seed corn production in different harvesting systems in Iran. Data were collected from seed corn farms in Alborz province. The results indicated the total average energy input and output of 51.1 and...

This study was conducted in the 2008-9 production year in West Azerbaijan province (Uromia Township). The Energy Ratio, Energy Productivity, Economic Productivity and Mechanization Index were estimated for apple production. Data were collected using random sampling for 80 face-to-face...
