Can hybric cars save YOU money? Yes, they can. HOW do hybrid cars save money? Through the use of self-charging batteries for propulsion. When the car moves, idles or brakes, the batteries recharge themselves; that's practically free energy. So what it all boils down to is: the more cheap electricity a hybrid car uses from its batteries, the less expensive fuel it uses. It really is that simple: hybrid cars save money because they use less gas. Buy one, and save.
