> Sorry, I didn't intend for you to infer that. I meant the same concept in both sentences. I am not talking about some more specific type of efficiency like fuel efficiency, which has nothing to do direct with the concept of economic efficiency.

I think you misunderstand the problem; "Producing efficient X" and "Efficiently producing X" aren't the same thing. The first is about the efficiency of the process of producing something (how the inputs are used to produce the output), the other is about the qualities of the output. The problem isn't "economic efficiency" vs. "some more specific type of efficiency", its production efficiency (in whatever terms) vs. efficiency of the product (economic or otherwise.)

I understand your claim. I'm trying to avoid a semantic argument by making it clear what I meant. I'm not arguing about what the "true meaning" of those phrases are. Just know I was referring to economic efficiency both times.
