Applied Second Law of Thermodynamics on the Wind Energy Over Iraq

Abstract

Although Iraq is an oil country, but it's have very large sources of renewable energy. This study was discussed the results of the wind energy and exergy for six regions in Iraq at three different turbine heights. The highest exergy efficiency was in Basrah then Anbar, Tikrit, Najaf, Baghdad, and smallest in Mosul. The exergy efficiency was increase by 60 % at height 50 m, while it's increasing by 70 % at height 100 m. The highest exergy destruction was in Mosul, Najaf, Tikrit, Baghdad, and smallest in Anbar and Basra. The exergy destruction decreasing by 33 % at height 50 m, while its decreasing by 68 % at height 100 m. The high energy efficiency was in Basra, then Anbar, Tikrit, Najaf, Baghdad, and the smallest in Mosul, the energy efficiency of a turbine increase by 52 % at height 50 m, while it's increasing by 66 % at height 100 m. And the highest output useful energy was in Basra, then Anbar,
