Cold storage has come a long way since the days of daily ice delivery?now, whether you want a bottom-freezer, side-by-side, or even a solar-powered refrigerator, there's a model for you. But perhaps the best refrigerator is the smallest—which uses less energy, lets out less cold air on opening, and keeps you shopping for fresh produce. These five models—in five different sizes—keep your cool no matter what. All electric bill estimates are based on the $.11 per kilowatt national average for 2008.
