I'd argue that "the cloud" makes traditional computing more efficient. Since their motto is "pay for what you use", it automatically aligns with motives for the most efficient use.

Not to mention that the usage of computers has reduced the need for much more power hungry methods. We can now efficiently calculate much stronger, lighter, easier to manufacture parts and building patterns.

There is no need to drive/ride/walk to a place to hear the message, radio broadcasting is much more effective, even though it itself consumes power.
