A wind turbine is a turbine powered by wind energy. Wind turbines are like air intakes for jet engines. When air enters, it first encounters a set of fixed blades, called the stator, that direct air into a set of rotating blades called the rotor. The air pushes against the rotor and appears on the other side, where it travels more slowly than it would outside the turbine. Not only do we need to understand the definition of a wind turbine, but we also need to think about how to solve some of the problems that arise.
