A vertical axis wind turbine having a plurality of upright airfoils pivotally engaged. A continuous adjustment of the angle of attack of the airfoils to oncoming wind is provided by rotation of a control plate connected to the vanes which are mounted upon a rotating drive plate. A vane can be employed to rotate the control plate to affect the continuous adjustment of the airfoils.
