Wind speed distribution and wind potential were studied at two places, that is, Fauji Fertilizer Company and Hawke’s bay of Karachi. Weibull parameters (k and c) were determined by analyzing the daily wind speed data at Hawke’s bay and FFC Mast for the years 2010 and 2007, respectively. The data was obtained from the website of Alternative Energy Development Board (AEDB), Pakistan. To find k and c, four methods (maximum likelihood, empirical method, method of moments, and energy pattern method) were used. The mean wind speed was also predicted by using these four methods.
