Wind power is a clean renewable energy to homes and businesses in form of wind farm. It will effective, if it placed in proper locations. The single wind turbine called a windmill or wind generator, constructing a turbine farm requires specific geographic and atmospheric conditions. A proper place for wind turbine is place that located on the steep hills or near the ridges which can see the landscape around. At elevated locations, especially where they sit above much of their surroundings, higher wind speeds are often experienced. The wind crossing the lower area becomes compressed as it meets the exposed side of the hill. Once the air moves above the ridge it expands again and speeds up as it moves into the lee side of the hill, where the air pressure will be lower. The force of wind begins from the distance upward to the hill. And it is down to the high-pressure areas by the form of wind blowing against with the distance of hill extending from the hill. The divergent distance is depending on the intensity of wind. It does not mean that no any obstacles that wind can pass, for instance tree or building. Cleaning the air that has little effect or no effect can prevent the changing power for wind turbine. Nevertheless, the place which is rough or uncommon environmental condition can affect to make turbulent weather. Both things will make air disturbance that approach to the wind turbine and not only restrain the operating efficiency but also damage to the turbine. The location that is proper for wind turbine is not just an operation of the changing of wind speed in any location but also depend on the limitation of planning and the requirement of grid connection.
