Take these simple steps to reduce their effect:

• Turn off lights that are not in use.
• Turn off televisions that are not in use.
• Turn off computers printers, fax machines, copiers and other electrical devices when not in use.
• Change light bulbs from incandescent to fluorescent in lamps and fixtures that are routinely left on for long periods. While fluorescent bulbs may cost more to purchase, you save money in energy and replacement costs. You can also replace incandescent bulbs with fluorescents wherever practical. Compact fluorescents last 12 times longer and use only 1/3 the energy of incandescent bulbs.
• Use bulbs that deliver the most lumens (light output) at the lowest wattage. Try to get all the light output you can.
• Avoid using long-life bulbs. They are the least efficient of incandescent bulbs. They cost more and provide less light. Use them only in areas where bulbs are difficult to replace, such as high ceilings or hallways.
• Use one higher-wattage bulb instead of several lower-wattage bulbs. One 100-watt bulb gives the same amount of light as two 60-watt bulbs, but uses 17 percent less energy. Make sure you do not exceed the manufacturer's recommended wattage for the fixture.
• Switch to low-wattage bulbs where only a small amount of light is needed.
• Put motion detectors on exterior lights.
• Use timers to turn lights on and off when you are away from home instead of leaving lights on continuously.
• Use dimmer controls, high/low switches or three-way bulbs to adjust the level of lightning to exactly what you need. Dimmers can help you save energy and increase bulb life, too.
• Dust your light bulbs regularly. Dust and dirt on light bulbs can reduce their illumination by 50 percent.
