I'm not convinced of the value of carbon counters. Like diet "points" counting, it only works for a subset of the population. I'd greatly prefer to see a more proactive approach - governments (state & local in particular) making consultancy services available to residents to provide advice on greening their homes and engaging directly with home builders on "out of the box" approaches for making homes and business premises more energy efficient.

There are some folks at http://www.energycoop.com.au doing related things. Maybe you could have a chat with them and see what happens?

Did you know that there's been a recent discussion on the new power meters that are being rolled out by the electricity companies? The data collected by the companies is only going back to the companies. There were a bunch of technologists who argued that the data should be available to the household, so that they could monitor their own usage, but I think the idea was squashed. Perhaps you could investigate that, and continue to lobby for access to that data.
