Switching from incandescent light bulbs to compact fluorescents is one of the easiest and most inexpensive ways to reduce your energy bill. In most homes, lighting accounts for 5 to 10 percent of the energy used. Business energy use for lighting is often much higher. CFLs use a quarter of the energy consumed by traditional incandescent lighting. Start by replacing bulbs that are used the most.

Fluorescent bulbs contain mercury and should be recycled. To find the closest hazardous waste disposal site call 1-800-recycle. For more information about recycling household lamps go to
