In 1941 the world's first megawatt-size wind turbine was connected to the local electrical distribution system on the mountain known as Grandpa's Knob in Castleton, Vermont, United States. It was designed by Palmer Cosslett Putnam and manufactured by the S. Morgan Smith Company. This 1.25 MW Smith–Putnam turbine operated for 1100 hours before ...
Loosely speaking, it seemed as if classically minded geographers favored the 12-wind system, but those of more practical bent preferred the 8-wind system. As the Dark Ages advanced, it could be expected for the 8-wind rose to prevail, but the guardians of classical knowledge, such as St. Isidore of Seville, preserved the 12-wind system for ...
A 2010 Harris Poll found strong support for wind power in Germany, other European countries, and the United States. [145] [146] [152] Public support in the United States has decreased from 75% in 2020 to 62% in 2021, with the Democratic Party supporting the use of wind energy twice as much as the Republican Party.

A 1.5 wind turbine of a type frequently seen in the United States has a tower 80 meters (260 ft) high. The rotor assembly (blades and hub) measures about 80 meters (260 ft) in diameter. [ 68 ] The nacelle , which contains the generator, is 15.24 meters (50.0 ft) and weighs around 300 tons.
The term originally derives from the early fourteenth century sense of trade (in late Middle English) still often meaning "path" or "track". [2] The Portuguese recognized the importance of the trade winds (then the volta do mar, meaning in Portuguese "turn of the sea" but also "return from the sea") in navigation in both the north and south Atlantic Ocean as early as the 15th century.

Knowing the wind sampling average is important, as the value of a one-minute sustained wind is typically 14% greater than a ten-minute sustained wind. [16] A short burst of high speed wind is termed a wind gust ; one technical definition of a wind gust is: the maxima that exceed the lowest wind speed measured during a ten-minute time interval ...
