The sentence presented is effective in the passive voice because it emphasizes that a change is necessary, regardless of who causes it, that is, it does not matter who will carry out the change.
The sentence "the need for change is immediate" has the verb "is," but does not assign any subject to the sentence. This makes the sentence like a passive voice sentence and this is effective because it underscores the urgency of bringing about a change. This happens because the passive voice determines that anyone can bring about this change since there is no one determined individual to make it and the need is great.
