【正确答案】 D

【答案解析】 Rhetorical Construction; Idiom
The intended meaning of the sentence seems to be that the electricity production of windmills is expected to approximately double by year's end. But instead of saying almost double, we have almost expected, which is an unclear idea. Also unclear is what the relative pronoun which refers to.
A The placement of almost makes it nonsensically modify is expected. What the relative pronoun which refers to is ambiguous: for example, does it refer to the expectation, the possible doubling, or the year?
B The resulting sentence misplaces the adverb almost.
C The phrase production is expected that it will... makes no sense—as opposed to, for example, it is expected that production will....
D Correct. This sentence clearly conveys the expectations of production: almost to double and thus to provide. There is no ambiguity as to what will be providing enough electricity.
E The referent of the relative pronoun which is ambiguous, and the conditional verb form would thus be providing is unnecessarily wordy.
The correct answer is D.
