You could call it a lightbulb exchange. But some say it's an easy way to save a lot of money.

Volunteers will visit some Atlanta homes and change out at least one incandescent lightbulb for an equivalent compact fluorescent lightbulb and consumers also will visit True Light Baptist Church from 12:30-3:30 p.m. Saturday to exchange its bulbs.

A national distributor of energy conservation products, blackEnergy, along with volunteers from the Concerned Black Clergy, the American Association of Blacks in Energy and Georgia Interfaith Power & Light, created "Lightbulb Swap 2008."

The annual event is billed as a way to introduce a cost-effective approach of "Going Green" to the African-American community. The event takes place Saturday at True Light Baptist Church, 47 Anderson Avenue NW, Atlanta.

The goal of the program is to educate consumers on the importance of saving energy and resources for the next generation.

According to the U.S. government's Energy Star program, by replacing just one traditional bulb, consumers can save about $30 or more in electricity costs over the bulb's lifetime. The five highest used fixtures in a home are typically the kitchen ceiling lights, the living or family room table and floor lamps, and outdoor porch or post lights. As a result, replacing five of these lightbulbs could save consumers as much as $150.
