    The daily mean wind speed data for 4 locations in Palestine over the period of 5 years (1997-2001) are collected, analyzed, and fitted to the Weibull distribution function. Weibull parameters are derived from the cumulative function of the observed data records, and used to calculate the mean wind speed and variance of the theoretical distribution, which have maximum values in summer months and minimum values in winter months, except Hebron station due to its higher elevation (1005 m) above sea level. However, Jericho station provides lower values of monthly mean wind speed (maximum, 2.56 m s-1). The second order polynomial is used to fit the relationship between the wind power and the mean wind speed. The monthly mean wind power density is higher during summer and lowers during winter except Hebron which is higher in winter and lower in summer months. The highest mean power values are 32.98 W m-2 in January and 37.85 W m-2 in July for Hebron and Nablus respectively, whereas the lowest mean power is 1.66 W m-2 in January for Jericho. The adjusted R2 of the polynomial fit is 99.8% for all stations except Hebron 70%. The following recommendations for further study are : • Manufacturing facilities for wind plant and wind turbine must be created in suitable sites. • It should be attended in selecting an appropriate site for the wind turbine. • In case to power generation, major problem is energy storage, we need to resolve this by linking wind generators with conventional electrical grid. • It should encourage the researchers to develop projects in the field of wind energy. • Where the wind speed is favorable, variety of applications of wind energy, short or long term research programmers may be undertaken for the utilization of wind energy in Palestine. V • Wind speed should be recorded in different locations of Palestine for precise studies in this field. • Decision makers should support researchers for continual studies.
