What continuing experience is showing us is that we do not know enough about any one power source yet to be able to focus on that to the exclusion of others.

Is What continuing experience is showing us a interrogative content clause and is the content clause in the predicate that we do not know enough about... an answer to that question in the sentence above?
Is enough an adjunct and is the PP about any one power source yet to be able to focus on that to the exclusion of others a complement of the verb know in the content clause?

Not exactly.

No.

[What continuing experience is showing us]
is
[that [we do not know] [[enough] [about any one power source]] [yet]
[to be able to focus [on that] [to the exclusion] [of others]]].
This is pseudo-cleft sentence.
What continuing experience is showing us is an NP formed with the fused relative 'what' (= 'that which') and a relative clause ('(which) continuing ...').
that we do not know ... to the exclusion of others is a content clause. It's the complement of is showing.
enough about any one power source is the complement of know. enough is a quantifier that appears without the noun it quantifies, understood to be information. [ I believe the big boys call this a headless NP, but don't quote me on this. ] about any one power source is a PP. (This PP does not extend to the end of the sentence, by the way.)
yet is an adverb/adjunct.
to be able to focus on that to the exclusion of others is a non-finite (infinitival) comparative clause that goes with enough (as in "We don't have enough to feed all these people").
Within this final clause you have three preposition phrases, shown above.
CJ
What X shows (US) is Y. ~ Y is complement of is.
X shows Y. ~ not the same as X is Y
'what' is a pronoun and functions as direct object of 'shows', and head of the underlined NP (fused relative). It would be taken as a noun clause in traditional grammar.
Yes.
I think so.
We don't know about it enough.
We don't know enough about it.
I see.
I understand that you mean that is that we do not know enough about any one power source yet to be able to focus on that to the exclusion of others is a verb phrase in which "is" is the head of the VP.
Thank you for the detailed, in-depth analysis.
