Efficacy/Efficiency, the first is about achieving a given result, the second also take into account the resources required. I could use an helicopter to buy bread two blocks away, the goal is achieved, so is effective, but is arguable very wasteful on inefficient.
Wasteful refers to the useless consumption or expenditure, so everything that doesn't directly contributes to the main goal is waste, something can be wasteful without being a complete waste, which only occurs if the goal is not achieved as you mentioned, but "wasteful" doesn't mean is a complete waste, just that have a considerable amount of resources not directed to the main goal. A Ferrari is wasteful but is far from waste. Even this is arguable tho, because depends on what the goal is, if is to impress people a Ferrari may not be wasteful and in fact be very efficient.
About Electron consuming too much is also debatable, to me it is, I tried for about 10min Atom with my usual 10+ files open and consumed much more than Vim doing the same thing, you can argue that Atom does things that Vim can't, I don't know, to my use case is wasteful because I don't care about those potential extra features. As I said, what is or not wasteful depends on everyone goals and criteria.
But the fact is that not because something achieve the goal is not wasteful and that something is wasteful doesn't mean is waste. Just like that something is dusty doesn't mean is dust. That's pretty simple logic.

@Fredrik Bengtsson, you beat me by seconds, I saw the notification bell just before y pressed the button tu submit.
