Some more concepts I had was to have a diagram of a house with each room being represented by an icon which tells what goes on in there and is coloured to show the level of energy being used.
I thought of having a "family tree" like system where it opens up and shows the details of each room and how much energy is being used. I don't like this as much as some of the others though because it seems to basic.
The one I have chosen to go with is the circles that expand out. I have decided to us the graph system seen in 'scanner.exe' and use that in my interface.
I was looking at ways to make my interface more fun and engaging by when you click on the specific area it opens up random data, for example: how many polar bears you killed, or pigeons killed due to your energy used in that area. I also thought about showing each appliance within those areas and how much they contribute to the overall area.

I looked at the lines connecting the circles as well and thought that I should have them so that the closer they are to the center the more energy they are consuming.
Also one thing I forgot to mention was that each circle will have an outer ring which is either coloured red, orange or green. This is just for a quick overview of the area and whether or not it is good on energy or bad.
