If the kitchen is the heart of the home, then its life blood is its appliances - those busy, underappreciated workhorses that cook the roast, scour the dishes and keep the ice cream frozen. But if you're ready to pick out some new appliances, don't judge a refrigerator by its cover.

Sure, style counts, but a stainless steel exterior isn't everything. These days, appliance manufacturers are focusing on building refrigerators, ranges, ovens, microwaves and dishwashers that not only look good but also offer innovative, intelligent features that cater to a homeowner's need to save time and space.

In addition, appliances are more energy efficient and earth-friendly than ever before. "Energy efficiency is definitely the No. 1 trend for manufacturers right now," confirms Jill Notini, communications director for the Association of Home Appliance Manufacturers.

It's clear that today's appliances will not only make your life easier, but also can help reduce home energy costs. That in itself might be enough reason to shop around for new kitchen appliances. Here's a quick guide to get you started.
