You are, I’m sure, familiar with the Energy Star certification. It’s a little yellow sticker found on all appliances that claim to show you what it will cost per year to run them under average usage. Of course, no one can really determine what average usage is. For a refrigerator, how many times a day do you open it? How full is it? For a washer or dryer, how many loads a day pass through it? The same for a television, perhaps even more so. How many hours is it on per day?
