A mechano-electrical energy generation system generates electrical energy from the passage of a vehicle over an inclined ramp assembly. This assembly includes an incline ramp that is rotatable about an axis proximate a vehicle roadway surface, and a safety decline ramp hinged with and rotatable with the incline ramp. The incline ramp is coupled via a roller assembly to a gravity wheel that drives a flywheel coupled to an electrical generator. As a result, passage of the vehicle over the incline ramp rotates the wheel via the roller assembly and drives the flywheel so that the electrical generator outputs electrical energy. When the vehicle exits the safety decline ramp, a counterweight rotates the wheel in a reverse direction, so as to bring the incline ramp and safety decline ramp to back to their original inclined positions above the roadway surface.
