With wind energy, ''efficiency'' is often confused with ''[capacity factor]''. | With wind energy, ''efficiency'' is often confused with ''[[capacity factor]]''. | ||
Wind turbines are actually quite efficient, extracting as much energy from the wind as physically possible, although at a rather narrow range of wind speed. | Wind turbines are actually quite efficient, extracting as much energy from the wind as physically possible, although at a rather narrow range of wind speed. | ||
