Rosslyn start-up will analyze your power usage

Sounds like there's competition in the local home-energy data analysis and advice field. The Washington Post had a column the other day about Positive Energy, a Rossyln start-up "crunches data on energy usage to create customized monthly energy reports and Web sites that inform and instruct homeowners on how to save money."

Seems they do it through power companies, not on a retail basis to individual consumers.

The company sounds similar to EarthAid, which will analyze your energy use for free.

Have you used either of these companies' services? If so, leave a comment saying how it went.
