The assessment of the percentage of loss in annual rates of wind power by influence of temperature on the in Samawa city-Southern Iraq is investigated for five years (2012)(2013)(2014)(2015)(2016). The study illustrates that the percentage of loss in annual rates of wind power range between 4.7% at the study period 2013 and 5.8% at the study period 2016. Objectives: In the present study, the influence of temperature on the resultant wind power in Samawa city-Southern Iraq is studied.

... : Data of wind speed, and temperature are measured at an altitude of 11 meters (altitude of meteorological Station of AL. Samawa) for five years (2012)(2013)(2014)(2015)(2016). This data used as input to a software computer program that was prepared for this study to solve the set of equations in section 2 for simulates the temperature effect on extracted wind power. Finding/Improvement: The study illustrates that the percentage of loss in annual rates of wind power range between minimum value 4.7% at the study period 2013 and maximum value 5.8% at the study period 2016. The study attributes that to the loss in the air density, and illustrates that the percentage of loss in annual rates of air density ranges between minimum value 4.7% at the study period 2013 and maximum value 5.8% at the study period 2016. The amount of percentage of loss in annual rates of wind power reduces with the increase in height. Application: Production of electricity from wind energy as renewable energy resources.
