A system and method for a piezoelectric-based vertical axis wind turbine (VAWT) are disclosed. The piezoelectric-based VAWT may generate electricity in response to a deformation (e.g., a stretching or bending) of piezoelectric material. For example, the piezoelectric material may be included on or within a wind turbine blade. The wind turbine blade may be struck by an object or may hit an object. Such an action may cause the wind turbine blade to vibrate and subsequently cause the piezoelectric material to deform and generate electricity.
