How big is a wind turbine?

Globally the average turbine size in 2012 was 1.84 MW and in Europe 2.2 MW enough to produce power for up to 1,202 European households. 

The largest onshore turbine is a 7.5 MW turbine with a rotor diameter of 127 m.

Offshore turbines currently reach just over to 6 MW with a rotor diameter of 120 metres – longer than a football field and powering around 5,500 average EU households.
