Analysis of energy and exergy utilisation of Jordan's agricultural sector

This paper presents detailed analysis of energy and exergy utilisation in the agricultural sector of Jordan, by considering the sectoral energy and exergy flows through the main end uses of sub-sectors. Artesian water wells, agricultural machinery, poultry and cattle farms consumed about 57.0, 12.3, 27.3 and 3.4%, respectively, of the total energy used by the agricultural sector in the year 2004. The main outcome of this study is that a large room exists for further improvements in this sector, since the calculated overall energy and exergy efficiencies were low, i.e. 37.3% and 23.5%, respectively.
