Energy Efficiency Wins Top Prize at EPA App Contest

The winner of best overall app at the Environmental Protection Agency’s (EPA) Apps for the Environment is called Light Bulb Finder, a free iOS and Android application that helps a user choose the energy efficient bulbs that best match their home’s current lighting conditions.

A Winning Light Bulb With the Potential to Save the Nation Billions
This 10-watt alternative LED bulb (which glows white when turned on) could save the nation about 35 terawatt-hours of electricity or $3.9 billion in one year and avoid 20 million metric tons of carbon emissions if every 60-watt incandescent bulb in the U.S. was replaced with the L Prize winner. | Photo Courtesy of Philips Lighting North America

Thomas Edison would be amazed. The conventional light bulb is getting some serious competition from a 10-watt LED bulb -- the first winner of the Energy Department's L prize.
