The largest turbine is GE's Haliade-X offshore wind turbine, with blades 351 feet long (107 meters) – about the same length as a football field.

How do turbine blades work?

Part of the turbine's drivetrain, turbine blades fit into the hub that is connected to the turbine's main shaft. The drivetrain is comprised of the rotor, main bearing, main shaft, gearbox, and generator. The drivetrain converts the low-speed, high-torque rotation of the turbine's rotor (blades and hub assembly) into electrical energy.

How does a turbine drive a generator?

Part of the turbine's drivetrain, the main bearing supports the rotating low-speed shaft and reduces friction between moving parts so that the forces from the rotor don't damage the shaft. Part of the turbine's drivetrain, the high-speed shaft connects to the gearbox and drives the generator.

What is a dynamo generator in a wind turbine?

The same thing happens in a wind turbine, only the "dynamo" generator is driven by the turbine's rotor blades instead of by a bicycle wheel, and the "lamp" is a light in someone's home miles away.
