Learn Spanish (Latin America): Tendremos que restringir el consumo debido a que no llueve. - We will have to restrict consumption because it is not raining.

debido a que is a formal causal connector that translates closely to "due to the fact that" or "given that." While porque (because) is perfectly correct for everyday speech, debido a que is preferred in formal contexts like public service announcements, news reports, or business letters. This sentence sounds like an official warning from a city.

Why do we need the word que in debido a que? Can I just say debido a no llueve?

No, you must include que whenever a conjugated verb (like llueve) comes next. You use debido a (without que) only when it is followed by a noun or noun phrase. For example, you would say debido a la sequía (due to the drought) but debido a que no llueve (due to the fact that it isn't raining).

What exactly does el consumo refer to in this sentence?

Literally, it means "the consumption" or "the usage." Because the reason given is a lack of rain (no llueve), it is heavily implied that they are talking about water usage (el consumo de agua). In official contexts, authorities often shorten it to just el consumo if the context makes it obvious to the public.

Why is tendremos in the future tense while llueve is in the present tense?
