Questions & Answers about Завод использует как солнечные панели, так и ветряные турбины.
The current lesson is about substitution (вместо того чтобы), but this sentence uses как ..., так и .... What does this structure mean here?
While вместо того чтобы (instead of) replaces one thing with another, как [A], так и [B] is an additive conjunction. It literally translates to "as [A], so and [B]," but it means "both [A] and [B]." It is a slightly formal but very common way to emphasize that two things are equally involved, rather than substituting one for the other.
Are солнечные панели and ветряные турбины in the nominative case here?
They are actually in the accusative case, acting as the direct objects of the verb использует (uses). Because they are inanimate plural nouns, their accusative forms are identical to their nominative forms. If the factory were using animate objects (like workers), their endings would change to look like the genitive case.
Why does the sentence use ветряные instead of ветреные for "wind"?
There is a subtle but important difference in Russian. Ветреный describes the weather (e.g., a "windy" day) or a frivolous personality. Ветряной (which becomes ветряные in the plural here) means "wind-powered" or "operated by the wind." Therefore, wind turbines and windmills always take the adjective ветряной.
Is the comma before так и mandatory?
