It's a kitchen staple: and also very likely the biggest energy hog you've got in your home. That's right, in many cases, your refrigerator usurps more energy than your TV, clothes dryer, and microwave combined—nearly 14 percent of your home's entire energy consumption. But it doesn't have to.
When it comes down to choosing a style, top and bottom freezer refrigerator models are typically more energy-efficient. But if you must have the side-by-side aesthetic, we've weeded out the five greenest: the best electricity saving, water filtering, and Energy Star-qualifying side-by-side refrigerators out there. All five—running much more efficiently than the average fridge—will save you big bucks on your energy bill. All electric bill estimates are based on the $.11 per kilowatt national average for 2008.

Eco Factor: Liebherr has a company-wide green commitment—it's the only manufacturer in North America to have every single one of its indoor refrigerators Energy Star rated. And this side-by-side is no exception: The savvy FrostSafe System keeps air continuously circulation in the compartments and precision electronic controls ensure that energy efficiency is always optimized.
