Abstract: Improvements in energy use efficiency are keys for sustainable energy management. Increasing the use of energy inputs in agro systems led to numerous environmental problems like greenhouse gas (GHG) emissions, loss of biodiversity, high consumption of non-renewable energy resources and pollution of the environment. Based on the total energy equivalents of the inputs and output in agroecosystems, the energy ratio (energy use efficiency), energy productivity, net energy and specific energy are calculated for energy analysis. To increase energy efficiency, energy input should be reduced without affecting the crop yield level or increase the production yield. Furthermore, in modern agroecosystems, burning fossil fuels results in the emission of CO2, nitrous oxide (N2O) and methane (CH4) that act as barriers to thermal radiation and prevent it from leaving the earth s atmosphere. In general, agricultural GHG emissions account for 10-12% of all anthropogenic GHG emissions. According to this, the identification of crop production methods that maximize energy efficiency and minimize greenhouse gas emissions is vital in agro systems.
