Huh, I’m not sure they are comparable.
Didn’t USB A and USB B use a master-slave relationship in which the male would (generally) always be the slave, whereas USB C uses agreement and discussion to decide the master and slave roles regardless of connector gender.
Please do correct me if I’m wrong. Also, do we say “agent” now instead of “slave”, or what is the new term?
~~“Batteries” is a rather broad category.
Are we talking hydroelectric batteries? Other potential or kinetic batteries? Chemical batteries (and what subcategory)? Or maybe hydrogen-based power storages?
Since there’s a dam on the list, I’d imagine “batteries” to be electrolytic power stores or hydrogen fuel cells, but the visualization remains lazy and perhaps borderline misinformative (depending on how nit-picky you are).
EDIT: The illustration might also use a simplified definition of a battery (to store, excluding conversion between kinds of power) instead of the different battery technologies which exist or the full definition, which could have one argue that batteries aren’t renewable by definition.
Though, that might be reading too much into it.~~
Actually, never mind, I’m probably too tired to go out on an adventure about the technicalities of the definition of “battery” to make any real amount of sense and not fall into edge cases.
I also misread “energy source” as “renewable”…
