In this study, wind energy density in the western region of Turkey was investigated by using the Weibull and Rayleigh probability density functions, and the Wind Atlas Analysis and Application Program. The hourly wind speeds and directions collected by the General Directorate of Electrical Power Resources Survey Administration were used. The dominant wind direction, probability distribution, Weibull parameters, mean wind speed and power potential of all stations were determined by the Weibull and Rayleigh model, and the Wind Atlas Analysis and Application Program. The results obtained with these models were compared with the measured data. Finally, it was found that these regions have a reasonable wind power potential and they are suitable for the plantation of wind energy turbines, but Gokceada and Gelibolu are the most promising and convenient sites for the production of the electricity from the wind power.
