I've never really understood the utility of any of the devices being
promoted by the electricity companies which all (as far as I understand
them) indicate your total electricity consumption. That's next to
useless as it gives you no real clue as to what is actually eating your
electricity.
The key thing you get is usage against time. If I come home, put the oven on, eat, put the dishwasher on then settle in front of the telly, then look at the energy trend over that period, I'll get a pretty good idea of the relative usage of those appliances, and the background usage that runs throughout the night can be narrowed down pretty easily too. Of-course you'd want some appliance meters to confirm suspicions or give extra detail, but you'd be surprised just how much you can tell from just the energy trend over time.
