Hotpoint refrigerator CTX21DABRRWW: too old?...

Question

Anyone knows what year is hotpoint refrigerator CTX21DABRRWW made? and how may kws per hour?

I am asking because I am considering to replace this frige. Seems that it is not energy-efficient. I don't have other big eclectricity users at home, but my monthly usage is around 500KWh. I suspect that this fridy is the one to blame.

any advice is welcome. thanks.
