A system for electrical power generation by utilizing wind draft force from vehicle traveling on roadways provide two types of wind turbine apparatuses, one type is for road side which sits along the side of a roadway; another type is for road center which is installed along at traffic divider line at middle of a roadway. When vehicle moves at high speed, lots energy is used to push away air in its way. By setting wind turbines on road side and middle of road, some portions of the wasted energy can be re-captured.
