What materials are used to make wind turbines?

According to a report from the National Renewable Energy Laboratory, wind turbines are predominantly made of steel (71-79% of total turbine mass); fiberglass, resin or plastic (11-16%); iron or cast iron (5- 17%); copper (1%); and aluminum (0-2%). Many turbine components are domestically sourced and manufactured in the United States (Wind Technologies Market Report).
