When shopping for a new washer, look for a front loading (horizontal-axis) machine. This machine may cost more to buy but uses about a third of the energy and less water than a top-loading machine. With a front loader, you'll also save more on clothes drying, because they remove more water from your clothes during the spin cycle. Look for the Energy Star label.

Not too much romance here, but essential for any functional kitchen. Buy the heaviest pans possible. Also, you should consider buying a non-stick silicon sheet: they make baking very easy!

When you do have to shop for a new appliance, look for the Energy Star label. Energy Star appliances have been identified by the U.S. Environmental Protection Agency and DOE as being the most energy-efficient products in their classes. They usually exceed minimum federal standards by a substantial amount.
