Get a Cooler Fridge: $17
If you're in the market for a new refrigerator—and who can resist the latest models' LED lighting, easy-open handles at kid-friendly heights, and other features?—choosing an Energy Star–rated appliance can save you money, since they're required to use 20 percent less energy than models not rated. The Environmental Protection Agency's Refrigerator Retirement Savings Calculator lets you figure out how much less you'd spend to run an Energy Star–rated machine versus one that isn't, based on where you live, the fridge's style, year and size (when we tried it, our savings was $17). You'll also be eligible for tax credits—and some states have rebate programs where they'll pick up your old refrigerator and pay you for it (for a list of offers, see the Database of State Incentives for Renewables & Efficiency).
