Optimal Estimation of Critical Angle for the Wind Power (Energy) to Generate High Electrical Power inBaghdad City

The wind energy is regarded one of the important renewed energies invested by man from ancient time to execute some of his works and he is still challenging and continuing in finding the best techniques to exploit as much as he could and consider them a new source for the renewed energy to meet his requirements. The aim of the research is to estimate the usability of the wind energy to get high efficient of electrical power in Baghdad city through the analyzing the impact of some explanative variables ( Mean Temp. , High Temperatures , Time of High Temperatures Registration , Low Temperatures , Time of Low Temperatures Registration , Heat Degree Days , Cool Degree ays , Rain , Average Wind Speed , High Wind Speed , and Time of High Wind
