Questions & Answers about Um die Kapazität zu erhöhen, wird ein zweiter Windpark errichtet werden.
Why are there two forms of the verb "werden" (wird and werden) in this sentence?
This is the Future I Passive construction. The first verb, wird, is the conjugated auxiliary for the future tense ("will"). The final verb, werden, is the infinitive required to form the passive voice ("be"). Paired with the past participle errichtet, it forms wird errichtet werden ("will be erected").
Why does "wird" come immediately after the comma instead of after the subject "ein zweiter Windpark"?
The introductory phrase Um die Kapazität zu erhöhen acts as a single block that takes up Position 1 in the sentence. Because the conjugated verb in a German main clause must always take Position 2, wird must come right after the comma. This pushes the subject (ein zweiter Windpark) to Position 3.
Could I drop "um" and just say "die Kapazität zu erhöhen, wird..."?
No, because you need to express purpose here. The construction um ... zu translates to "in order to". Without um, you would just have a basic infinitive clause that wouldn't grammatically or logically connect to the main clause to show why the wind farm is being built.
The past participle of "errichten" (to erect) is "errichtet". Why is there no "ge-" at the beginning?
