What is the history of wind turbine?
Megawatts of the first wind turbine on Grandpa’s Knob size, Castleton, VermontWind machines were used for grinding grain in Persia as early as 200 BC This type of machine was introduced in the Roman Empire in 250 AD In the 14th century Dutch windmills were in use to drain areas of the Rhine River Delta. In Denmark, in 1900 there were about 2500 windmills for mechanical loads such as pumps and mills, producing estimated combined peak power of over 30 MW. The first windmill for electricity production was built in Cleveland, Ohio, by Charles F. Brush, in 1888, and in 1908 there were 72 wind power from 5 kW to 25 kW (7-34 hp). The larger machines were at 24 m (79 m) with four leaf towers 23 m (75 ft) rotor diameter. In the 1930s windmills were mainly used to generate electricity on farms, mainly in the United States where distribution systems had not yet been installed. During this period, high tensile steel was cheap, and windmills were placed above prefabricated steel lattice towers open
