Most wind turbines need a minimum wind speed of about 7 to 11 mph (3 to 5 m/s) to start generating electricity. This threshold, called the “cut-in speed,” is the point where the blades begin spinning fast enough to produce usable power.

A wind turbine generates electricity by using the kinetic energy of wind to spin its blades, which are connected to a rotor. The generator then converts this mechanical energy into electrical energy.

Most onshore wind turbines have a capacity of 2-3 megawatts (MW), which can produce 6 million kilowatt hours (kWh) of electricity every year. Over the course of a year, a turbine will generate about 30 of the theoretical maximum output, known as the capacity.

How much energy does a wind turbine actually produce: A wind turbine with 1 megawatt capacity can generate an average of 3 million kilowatt hours of electricity annually.
