Trains can already be electrified without the need for batteries. For the case of buses, I think there is an elegant solution that they have begun to use in my city. Historically, they already have been electric cables around the city for pantograph buses. However, it is expensive to run electric cables around the city, so they are only a handfull of lines using this technology. Now they are introducing hybrid battery / pantographs buses. Which I think a good compromise because you only need to equip a fraction of the line with electric cables, and the battery takes care of the rest. Because of that, you don't need a huge battery for the bus to be able to run all day. It can recharge periodically on the line with the pantograph. Concerning trucks and cars, yes that shit needs to be electrified ASAP.
