Relight Your Life Each incandescent bulb you replace with one that's Energy Star qualified saves 75 percent in energy use and about $30 in electricity costs over the life of the bulb. It's an easy switch, and if every U.S. household replaced just one, we'd save $600 million a year. While compact fluorescent lightbulbs (CFLs) are energy efficient, they still contain mercury, which is not something we want in our landfills. A better option is to hop onto the next wave of energy-efficient lighting: light-emitting diodes (LEDs). They have the same soft light we've grown accustomed to from incandescent bulbs but have no mercury, are far more energy efficient, and have a much longer life span (25,000 hours or more). While it can be difficult to find stylish LEDs, Koncept's Z-Bar lamps (from $129) shine above the rest.
