In reference to your third point, did you know you can click each appliance to remove or add it back into the total calculated?

I liked it and found it to be fairly accurate in the estimate it generated when I selected my appliances, maybe I am an "average" electricity consumer.

I was initially confused about the stars, and once I understood what they meant, I felt that detail was under employed.

I too would love to see the raw data that was used to generate the averages.

The appliances are sorted from using most energy to using least energy.

It's a shame the interaction is vital to ensure any knowledge is gained from the graphic. On it's own, without interaction, it's pretty unrevealing. I would have each appliance given a size (surface area) in relation it it's energy use/cost. Then the viewer will have an immediate understanding of what are the most energy consuming/costly appliances. The interaction should serve as a tool to gain further information, not as a way to reveal the purpose of the graphic (which is surely to enlighten the viewer). The stars add confusion, for me, which could be better revealed through interaction.

Most of these appliances are not in continuous use, so the cost calculations must have incorporated estimates of how much the average household uses each appliance. Providing these as pop-up information (e.g. average dryer use 4 hr/week) would make the graphic much more useful.

On the other hand, the yield per kilowatt-hour of the intermittent-use appliances seems to assume that the appliance is running continuously, but 5 hr of refrigerator use isn't the same as 5 hr of the motor running.

Good or whack? I can't decide.

Admittedly, it's not exactly quantitative data, but I wonder...

have annual costs of more than $300, the next 4 cost between $100 and $200, etc. In particular, a lot of the smaller appliances at the bottom half of the chart cost only $10 annually or less.

Basically, you should never buy stuff with features you don't need.

I am very impressed with the layout as it is and do not see that it needs improving. Using small images makes it faster to locate your appliances. Once you understand that large appliances are at the beginning and small ones at the end, you should be able to locate the ones you want easy enough. If there was a couple of hundred images it would probably be a good idea to group them but there are only 53, so I think its OK as it is.
