I'm going to say something like : "Try and save on about your electricity usage". I guess I can rephrase it using the verb "economize", but I have no idea how shall I do that! I've made a sentence and wrote it down below. Please have a look on it and let me know if it sounds natural. If not, then please tell me what shall I say using the verb "economize" to indicate the same message:
- We must economize on electricity usage.
For me, it sounds absolutely natural, but when I google it, I hit only 7 results.
