Turbine Information
Scale
Wind turbines are placed on towers to take advantage of stronger winds at height. As a rule of thumb the tower height is about twice the blade length; the blade length being set to maximise the area of the disk which the blade sweeps to extract energy from the air. In general cost efficiencies improve as the scale is increased. So wind turbines are large structures. A 2 megawatt turbine tower may stand about 80 metres tall and have 40 metre blades: a total height from base to blade tip of the order of 120 metres.
