Lots of words to say you don’t understand what you’re talking about.
At the most simple level monopolies extract profits through raising prices above that of a competitive market. This price increase reduces total sales even as it drives up profits.
As such the existence or non existence of a monopoly would change how much energy/etc AI was consuming among a host of other effects completely independent of how much utility it provided.

That’s genuinely funny.
