June 11, 2012 (Siemens)

“Siemens has produced the first batch of its new 75 meter long B75 rotor blades. [It is the world’s largest fiberglass component cast in one piece.] They will be installed on the second prototype of Siemens' 6-MW offshore wind turbine, which will be erected in the second half of the year in Denmark's Østerild Test Station…”

“The combination of intelligent design and low weight has a correspondingly positive effect on the power generation costs for wind energy. [Siemens’ turbine capacity has grown by a factor of 200 in the last 30 years]…”
