Implementation of wind turbines has been increased significantly because of its availability, easy and low cost generation around the world. Meanwhile in Bangladesh wind energy conversion is a very recent concept compared to other renewable energy conversion techniques and yet in many places research is going on to measure and analysis the wind velocity. The primary target of this research is to determine the wind prospects of Teknaf coastal area in Bangladesh by developing a statistical analysis of wind velocity at that region and to propose the design of blades for a low-speed wind turbine using theoretical analysis of power availability and wind velocity at different heights. The design approach can be applied successfully to develop a low-speed wind turbine's pole and blade construction.
