Overview of Geography
There are seven blade manufacturing facilities in the U.S., located in five different states (Figure SC.1). For more discussion on the role geography plays in the wind turbine manufacturing industry, please see the “Wind Turbine Manufacturing” step. Table SC.1 provides more details on the major tower manufactures. According to the DOE report, 70 to 90 percent of towers are manufactured domestically, primarily due to the logistic difficulty in transporting them in long distance.
