Wind Power Question: What are wind turbines made of?

Answer: The towers are mostly tubular and made of steel, and generally painted light grey in colour. The blades are made of glass-fibre reinforced polyester or wood-epoxy which keeps them light and extremely durable. They are light grey as this is the colour which is most inconspicuous under most lighting conditions. The finish is matt, to reduce reflected light and glare.
