National Wind Watch | Output From Industrial Wind Power
On average, therefore, wind turbines do not generate near their capacity. Industry estimates project an annual output of 30-40%, but real-world experience shows that annual outputs of 15-30% of capacity are more typical. With a 25% capacity factor, a 2-MW turbine would produce. 2 MW × 365 days × 24 hours × 25% = 4,380 MWh = 4,380,000 kWh.
How Do Wind Turbines Work? | Department of Energy
A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.
