We all know that switching from incandescent lightbulbs to compact fluorescents can help save money and energy over time. But did you know those CFL bulbs come in a wide variety of wattages? For little-used areas, like closets and hallways, don't always opt for the bright white, high watt bulbs. Instead, choose lower wattage bulbs that create just enough light. They'll use less energy, last just as long and will save you money in the long run.
