WattzOn
WattzOn is a website which provides tools for assessing your energy usage and comparing it to others. It offers a questionnaire for estimating your usage based on your housing, commuting, flights taken and other factors. You can then see visualizations breaking this information down as well as comparing it with the average, or with individual other users. There are tools for sharing your energy information on twitter or your blog, as well as a game for 'facing off' with other users. WattzOn also accepts data from certain kinds of internet connected power meter for inclusion in your profile.
