A nacelle is the housing at the top of a wind turbine that contains the main components for converting wind energy into electricity. Think of it as the "engine room" of a wind turbine. It's a large box-like structure that sits on top of the tower and houses important machinery like the gearbox, generator, and control systems. When people mention nacelles in their work experience, they're typically referring to their involvement with assembling, maintaining, or repairing these crucial components of wind turbines.
