The best places for wind farms are in coastal areas, at the tops of rounded hills, open plains and gaps in mountains - places where the wind is strong and reliable. Some are offshore.
The propellors are large, to extract energy from the largest possible volume of air. The blades can be angled to "fine" or "coarse" pitch, to cope with varying wind speeds, and the generator and propellor can turn to face the wind wherever it comes from. Some designs use vertical turbines, which don't need to be turned to face the wind.
The towers are tall, to get the propellors as high as possible, up to where the wind is stronger. This means that the land beneath can still be used for farming.
Wind power is a clean renewable energy to homes and businesses in form of wind farm. They are only 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. The place of a wind farm should be flat and high position. The rough terrain can cause the possible wind-blockage, slowing airspeed through the farm. The speed of wind increases at higher altitudes, however it is so important that all of flat area is elevated. For this reason, many wind farms are located on hilltops, but the hilltops themselves may be flattened if they are not naturally leveled.
