STRONG WIND AT SEA

Windpower is proportional to the cube of wind speed (P = ½ ρAV³). Thus, a modest increase in mean wind speed can translate to a large increase in annual electricity production. For example, at the height of 50 meters over Denmark, the annual mean wind velocities are 9 m/s over large regions of Danish North Sea (see Exhibit-1, in red color), which are 50% higher than those on land (6 m/s; see Exhibit-1, in green color). Therefore, over these regions, the same wind turbine can produce 3.375 [= (9/6)3] times the electricity at sea than on land!
