If an electric-energy-interface is set up to produce power, then it will also show on the Consumption side as draining 0W. Conversely, an interface that consumes power shows as "producing" 0W in the graph.

Basically, it's superfluous at best and confusing at worst.

Similarly, if an interface produces or consumes power but is disabled by script, it shows in both sides of the graph as producing and consuming 0W.

I figure if an entity is producing/consuming 0W, it shouldn't show up in the list at all... right?

That would be awful. All your solar panels would disappear from your network every night.

I'm not convinced that's a bad thing. When an item stops being produced for long enough to fall off the production graph, that item disappears.

You won't be able to see what is a member of the network.
