These refrigerator and dishwasher covers come in either adhesive vinyl, magnetic panels or real stainless steel. Could they be greener? Sure. Should you replace your old energy gulping appliance with something that merely sips electricity? Not necessarily. Keeping that hunk of trash out of the landfill might be a good idea. Plus if you're renting, you generally don't have that option. These covers from Appliance Art come in a variety of finishes including stainless steel, chalkboard, whiteboard, or other artistic options. Or you could just turn that old refrigerator into a dog house.
