... will be the number of locks and the energy consumption of locks. River barges on systems where no locks are required, or where locks are self filling and require only gate operation, will show up better than on systems where water must be pumped.

OTOH, that is one area that not only can be electrified but in many cases already is, so it can directly tap renewable electric power sources as those come on line ... electrifying the river barges themselves is a substantially more difficult proposition.
