With the globalisation of the wind power industry, Vestas
established its own blade factories in Denmark, Germany, China, the
United States, etc. In 2011, Vestas announced the introduction of a
7 MW wind turbine with a rotor of 164 m diameter—the biggest
in the world at that time—to be launched in 2014. Each blade is as
long as nine London city buses.

produces 13.5 million kWh per year.
