This logic is plain silly. You're not simultaneously on the gas and the brakes at the same time. The weight of the batteries and electric motors pales in comparison to the whole vehicle.
- w-j-w 5y agoThe difference is how the electricity in the battery is generated. Even if your local power grid runs on coal, the electricity coming out of the wall is WAY greener than electricity coming from the gas motor. If a hybrid doesn't plug in, then the only way to get electricity into the battery is by using energy which is created by running the gas engine. Sometimes this is direct, and sometimes this energy first gets turned into momentum of the car to be later reclaimed by regenerative braking. It doesn't matter that they don't happen at the same time.
