Energy use efficiency, GHG emissions, and carbon efficiency of paddy rice production in Iran
The energy efficiency, greenhouse gas (GHG) emissions, and carbon efficiency of paddy rice production were analysed in Sari in the Mazandaran province of Iran during 2011–2012. Data was collected through questionnaires and interviews with paddy producers. The results showed that the net energy gain was 27,932 MJ ha-1 and energy efficiency was 1.83 during production. The results o...

متن کاملEnergy End-Use Efficiency
Increasing energy end-use efficiency—technologically providing more desired service per unit of delivered energy consumed—is generally the largest, least expensive, most benign, most quickly deployable, least visible, least understood, and most neglected way to provide energy services. The 46% drop in U.S. energy intensity (primary energy consumption per dollar of real GDP) during 1975–2005 rep...
متن کاملthe selection of best tillage implements in terms of energy use efficiency using simple additive weighting methodology
introduction main part of energy consumption in agricultural mechanization is tillage operations therefore optimization of energy consumption in tillage operation is very important. a management method for system to optimize in agriculture is simple additive weighting (saw) methodology that this method can operate according to criteria of the systems. this method states that, which system has b...
متن کاملNon-Parametric Energy Use Efficiency, Energy Ratio and Specific Energy for Irrigated Wheat Crop Production
In this paper, non parametric Data Envelopment Analysis (DEA) was subjected to the energy data of wheat producers in Punjab state, India, and technical, pure technical and scale efficiencies were calculated for farms both category wise and zone wise. The main objective was to determine the strength of the correlation between non-parametric efficiencies and indices such as energy ratio and speci...
