Questions & Answers about Los electrodomésticos nuevos gastan menos electricidad.
Why is gastan used here instead of a word like usan?
While usan (use) or consumen (consume) are also perfectly correct, the verb gastar is heavily used in Spain to mean to use up or to consume when talking about resources like electricity, water, phone battery, or money.
Is electrodomésticos the only way to say appliances?
It is the most accurate word for household appliances. It is a compound word made of electro- (electrical) and domésticos (domestic/household). If you are talking about smaller, general electronic devices, you might just use the word aparatos (devices/gadgets).
Would the meaning change if I said nuevos electrodomésticos instead?
Since electricidad is feminine, why doesn't menos change to match its gender?
The word menos (less/fewer) is invariable. This means it never changes its ending to match gender or number. It is always menos, whether it describes a feminine singular noun like menos electricidad or a masculine plural noun like menos libros.
