From an article by Dan Haugen in Midwest Energy News:

A mobile app that helps people perform their own home lighting audits is the winner of a U.S. Environmental Protection Agency “Apps for the Environment” challenge.

Light Bulb Finder was created by a Milwaukee, Wisc., app developer called Eco Hatchery. Co-founders Adam Borut and Andrea Nylund learned they won the challenge last week, and on Tuesday they’ll be in Washington, D.C., to accept the recognition. . . .

The app was released for iPhone and Android in late 2010. It lets people walk around their home and use icons to identify the type of bulb currently used in each light fixture. After entering a zip code and the estimated daily hours of use for each bulb, the app suggests more efficient replacement bulbs, as well as a detailed projection of savings, in dollars and carbon emissions.

“We want to provide people with meaningful, individualized feedback so that they can make the smartest decision based on their priorities,” Borut said.
