Modern wind turbines are generally classified by power output (and hence size), e.g., from 400-600 kW up to 3 MW per unit. Most turbines today are horizontal axis with 3-blade rotors and are installed in sections to minimize local disruption. The operation of the nacelle, electrical generator, wind sensors, hub, and blades are all explained. [9:53]
