The United States Department of Energy reports that most modern land-based wind turbines have blades of over 170 feet (52 meters), resulting in a total rotor diameter longer than a football field.
According to The United States Department of Energy, most modern land-based wind turbines have blades of over 170 feet (52 meters). This means that their total rotor diameter is longer than a football field.
The United States Wind Turbine Database (USWTDB) provides the locations of land-based and offshore wind turbines in the United States, corresponding wind project information, and turbine technical specifications.
A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade.
The small wind turbine market, valued at $117. 3 million in 2025, is projected to experience robust growth, exhibiting a Compound Annual Growth Rate (CAGR) of 18% from 2025 to 2033. This expansion is fueled by several key drivers.
