Cup-type impellers are utilized on wind energy machines which are driven according to a first embodiment to rotate about a vertical axis and according to a second embodiment to rotate about a horizontal axis. In the vertical axis embodiment, the shaft driven by the cups is coupled to one or more offset generators by a gear. Preferably, a single generator mounted to rotate about a vertical axis is utilized. The rotor of the generator is supported by a low friction vertical bearing. In a second embodiment, a pair of cone supports is utilized to drive a horizontally disposed shaft. The shaft is oriented normally with respect to wind direction by utilizing a wind vane mounted on a separate support which detects wind direction and transmits information regarding wind direction to a platform supporting the drive shaft. Preferably, the generator is mounted directly on the drive shaft.
