Increasing Energy Awareness Helps

I'm sure a lot of Prius owners feel a lot like this owner:
One of the most fascinating parts of owning a Prius has been the ability to monitor how energy is used and distributed while it is in motion. It also displays the car's current fuel economy as well as the outside temperature. Touching the pad labeled "consumption" brings up a bar chart depicting gasoline mileage. It also shows how much energy has been delivered to the battery. The screens are endlessly informative. And as a new owner, I found my emotions rising and falling by how well I was doing on fuel economy. I felt victorious when the bar would zoom to 100 mpg, deflated to see it drop below 20 mpg.
That seems insightful. As soon as someone becomes aware of their behavior with respect to energy consumption, they want to optimize it (read: save energy). I think there is a market for home energy monitors, as well as monitors for the car too. But I really think it could help in the home. You can imagine programming a monitor to alert you when your consumption hits a certain level. That would be a really great way to keep your consumption capped & your costs down.
I have heard that owners who have a battery-backup solar system tend to watch their battery charge level like a hawk. I'm sure it's the same with grid-tied systems that employ net metering.
The notion to "do better" seems to be hard-wired in humans. I'm sure if we had more energy monitors showing us how much we are using, we'd use less.
