What is the difference between these sentences, one uses of and the other for:
The body uses carbohydrates as the main source of energy.
The body uses carbohydrates as the main source for energy.
Does the first sentence, using of, indicate that we get our energy from carbs; and the second, using for, indicates that we eats carbs in order to have energy.
Thanks.

I read "source for energy" as an inferior or mistaken way of saying "source of energy", i.e. a substance from which energy is derived.

So, you think that using 'for' here sounds wrong? But is it actually wrong? Because I have heard people say that 'the nutrient carbohydrate is for energy'. But I think as you pointed out if I use the word source, it is an indication that energy is derived from carbs. Right?
However, is would be correct to say: our body uses carbohydrates for energy.

It is specifically the phrase "source for energy" that I object to. One thing is a source of another thing, not for. Your other phrasings seem tolerable.
