Okay, I can see Wattvision being a useful tool for educating the consumer. I like that they also allow you to look at other households power consumption data. Someday it could lead to a conversation like:

John: Hey neighbor!

Jill: Hey John. What's up with the super-hot weather these days? Good thing I installed that AC unit a few months ago.

John: Oh, you have AC? I do too, but I looked you up on Wattvision and your power consumption is way lower than mine.

Jill: Oh, that's because my unit has a variable speed motor. And it has power factor correction built into it so it draws much less current from the grid.

John: You're so cool Jill!
