Members of the North Carolina Air National Guard, located at the Charlotte Douglas Intl. Airport, take conserving energy very seriously. The 145th Civil Engineer Squadron is taking steps to promote awareness of the little things everyone can do on a daily basis to be more energy efficient and be more aware of energy and water conservation. Shutting off lights is a great start. Replacing older lights with compact fluorescent lights (CFLs) or light-emitting diodes (LEDs) use three-quarters of the electricity and last 10 times longer. Occupancy sensors can save between 15 and 30 percent on lighting costs. Everyone plays a key role in saving energy. (U.S. Air National Guard photo by Master Sgt. Patricia F.
