Disclosed herein is an improved billboard system and method of use thereof. One or more vertical axis wind turbines (VAWT) are mounted onto the top portions of posts supporting new or previously constructed billboards. The vertical axis wind turbines, which are configured to rotate regardless of the direction of the wind, generate electrical power that is used to provide the power needs of lighting display elements (lights, screens, etc.) found on the billboard. The turbines are also used to charge batteries that may later be used to supply power to the billboard during periods when the turbines do not generate sufficient power or when one or more of the turbines are not operational. Surplus power not used to power the display elements or charge the batteries may be transmitted to the utility power grid. The billboard system may be monitored and controlled from a remote location via a communications network.
