Exactly that. We don't need to replace every car or plane out there. If we're able to build a renewable electricity grid and shift heating to using that clean electricity instead of gas or oil, we can save much more than by using electric transportation. But for that we'd need more clean electricity supply which isn't intermittent or can work as storage.
