Energy Savings: Lighting

1. Switch to CFLs.
A CFL now costs about $3 and uses about $22 in electricity over its 10,000-hour lifespan, equaling a mere $25 investment. By contrast, an incandescent bulb lasts 1,000 hours, so it would require 10 bulbs at $5 a pop to equal one CFL. Not to mention the fact that each incandescent uses $80 in electricity over its lifespan.

2. Color equals quality with CFLs
If you're looking to save at least 75% on your energy bill with CFLs, but you prefer the kind of light an incandescent bulb emits, choose CFLs that are between 2700 and 3000 degrees. They're labeled "soft white" as opposed to "bright light" or "daylight."

3. Look for that blue and white label.
ENERGY STAR-certified light bulbs use about 66% less energy than standard incandescent lighting. Visit ENERGY STAR for specific product recommendations.

4. Look toward LED and OLED lighting.
Use CFLs in place on incandescent bulbs whenever possible, but keep an eye peeled for LED and OLED lighting. They're just starting to make their way into the household, and happen to be the most energy-efficient option of all.
