Wind Power: A Renewable Alternative Source of Green Energy

In the study, the statistical analysis of wind speed data has been carried out for different locations of Bangladesh over the period of ten years from 1998 to 2007. The hourly measured wind speed data above 30 m height has been collected from Bangladesh meteorological department and sorted in sequence of appropriate frequency like hourly, daily, monthly and annually. The data has been fitted for Weibull’s distribution and determined two important parameters like Weibull’s shape factor and Weibull’s scale factor by three methods and compared to each other. The theoretical available power in Watt/m2 has been determined for the prospective wind sites. It also determined the practically extractable Power by wind turbine in Watt/m2. Finally, it has been found that the available power in the wind can be used for lifting water for irrigation purpose in the dry season.
