Smart electricity meters are all the rage in the UK and Europe. There’s even Google PowerMeter to collect your smart meter’s stats and display them in colorful ways. BC Hydro nearly rolled out smart meters province-wide until the opposition helped the government realize that they’re really expensive.

But just knowing how much energy you’re using might not cause you to use less. After all, BC Hydro already tells you how much you’ve used per bill. Nudge says that the trick is to make people who use more than the average amount of power to realize where they stand. And Jack will tell you that a bit of a game is the best way to get people who already use less than average to use even less.

A new site Welectricity = electricity monitoring + social networking. You enter your Hydro bills and then compete with your friends to lower your electricity use.

I haven’t been in my current house long enough to have enough data for my profile, and I don’t have any friends, so I can’t tell you that much about how the site works. Can you give people who live in detached rental houses in cold parts of the country a handicap? Can you have “most improved” competitions as well as absolute competitions? It was only launched last Earth Day, so perhaps all these features as coming.

Go sign up so I can beat you.
