The problem I see (remembering my experience as a new player) is that it is not really clear what the difference between "energy consumption" and "drain" is, especially as drain is not displayed when an item is in inventory or crafting.Energy consumption: 13 kW
Drain: 400 W
I propose that the numbers instead be displayed like this:
This puts the two closely-related numbers right next to each other (reducing the number of lines of text), and explains what the difference between them is, while still being short. I replaced the words "Energy consumption" with "power" just so it'll still fit on one line in the right side info bar (I think…), but also people who like to keep energy vs. power straight will like it (a less shortened phrase would be "Energy use").Power: 400 W + 13 kW if active
This also benefits semi-experienced players by making the drain included in item tooltips. Don't remember whether different inserters have different drains? Now you can just sweep over the crafting menu and find out.
Another version that would be a bigger change (because it adds drain to consumption), but might be even clearer, would be:
Power: 400 W idle, 13.4 kW active
