The first wind turbine for electricity production was built in Scotland in July 1887 by Prof James Blyth of Anderson's College, Glasgow. Blyth's 10 m high, cloth-sailed wind turbine was installed in his holiday cottage at Marykirk in Kincardineshire.

How big are the blades of a wind turbine?
For an average 1.5 MW turbine, the blades are between 35 to 45 meters. This gives an average rotor diameter of around 75 to 100 meters.
