The relay must stay on its state. When an electrical impulse is sent to it, it should switch its state and should maintain its status.
So I am really curious about it. Is there such a thing for saving lots of power?

Yes, they go by various names such as a bistable relay, latching relay, or impulse relay. Common in small (telecom style 2A or less) and also some power relays have this function.
There are various methods of actuating them, the small ones typically have either two coils (pulse one coil for 'on', pulse the other for 'off') or single coil (reverse polarity pulses for on vs. off).
Some of the power ones are alternating (pulse on, pulse off). One application of the high-power relays is for electrical metering where the power can be remotely switched off in case of bill non-payment by the customer.

You control the coil(s) and give it a brief pulse to put it in the desired state. That is typically done with electronics.

You are getting confused with a relay circuit that electrically latches the relay on. A latching relay is bi-stable. It has two stable positions. It uses two coils to switch it - or one but you have to reverse the polarity.
