With wind energy, ''efficiency'' is often confused with ''[[capacity factor]]''. | With wind energy, ''efficiency'' is often confused with ''[[capacity factor]]''. | ||
Wind turbines | Wind turbines can be quite efficient, capturing and converting as much energy from the wind as physically possible, although at a rather narrow range of wind speed. | ||
At wind speeds slower than ideal, there is not enough wind energy to generate power at the full rate of the wind turbine’s design. | At wind speeds slower than ideal, there is not enough wind energy to generate power at the full rate of the wind turbine’s design. | ||
At faster wind speeds, the blades must be pitched to be less efficient, so that their rotation rate remains constant. | At faster wind speeds, the blades must be pitched to be less efficient, so that their rotation rate remains constant. | ||
