Diese Angaben zum Stahlbedarf für Windrad-Fundamente sind um ein Vielfaches zu hoch. Je nach Anlage und Untergrund werden für den Sockel um die 100 bis 200 Tonnen Stahl benötigt.

The review says the claimed steel requirement is far too high: foundations use about 100–200 tonnes, depending on the turbine and ground. It cites examples ranging from 80 to 150 tonnes of steel for common turbine foundations, and says the claim of 1,300 cubic metres of concrete and 3,500 tonnes of steel is exaggerated.[S1]
