This paper focuses on the amount of diesel consumption as one of the non-renewable energy sources consumed by the agricultural machinery and water pumps in wheat and corn farms in Dire County,Kermanshah Province, Iran. The population of the study was determined by Bartlett table. Stratified random sampling method and census was used for the selection of respondents. The sample was composed of 2...

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...

introduction energy analysis of agricultural ecosystem is essential for sustainable production. the relation between agriculture and energy is very close. agriculture is an energy consumer and the energy supplier. agriculture’s use of energy is recognized in three external inputs: labor, machines, and fertilizers (connor et al., 2011). significant gains in energy efficiency were arisen in agric...

ABSTRACT- Energy use patterns and the contribution of energy input vary among farming systems. The optimal use of improved farm machinery coupled with the optimal use of other recommended sources permit an increase in paddy yield up to potential levels. In order to determine the effect of production systems on energy use efficiency focusing on mechanization for paddy production in Khuzestan pro...

The use of renewable energy in power generation and sudden changes in load and fault in power transmission lines  may cause a voltage drop in the system and challenge the reliability of the system. One way to compensate the changing nature of renewable energies in the short term without the need to disconnect loads or turn on other plants, is the use of renewable energy storage. The use of ener...

abstract the aim of this study was to determine the input–output energy consumption in different levels of tomato production. the data used in the study were obtained from 140 tomato growers in different villages of marand township by using a face to face questionnaire. the results showed that the amount of energy consumed in tomato production was 65.2 gjha-1 which about 51% of this was generat...
