Normally we assume that the excess kinetic energy of a car in motion will turn into electricity charged into the battery system of a hybrid vehicle. For example, when the car drifts, when we apply the brakes, when the car goes downhill, when the car turns.
That’s true but not enough. In fact, the renewable energy of hybrid vehicles includes excess kinetic energy and the potential energy of the vehicle. That depends on the location of the car. It is easy to be hospitable, if a hybrid car is at the top of the slope will receive greater renewable energy than a hybrid car that is at the end of the slope even though the subsequent travel distance of 2 cars is equal.
