The present invention relates to a blade for a wind power plant with a circular pitch bearing, whose pitch axis is angled relative to the longitudinal axis of the blade, and wherein the blade with a root part and the pitch bearing are arrange on an approximately elliptic cross-section. The invention further relates to a wind power plant in general having a pitch- adjustable blade mounted in a pitch bearing such that the distance between the outermost part of the blade and the tower is increased when the leading edge of the blade is pitched up in the wind. This is accomplished in that the longitudinal axis of the blade is angled in a particular way compared to its pitch axis. The invention also relates to a method of controlling a wind power plant, including to increase the rotor area and/or increasing the distance between the outermost part of at least one blade and the tower by regulating, during operation, the pitch of a blade about a pitch axis which is angled relative to the longitudinal axis of the blade.
