Take a look at your cookware today. Is the bottom flat, or is it slightly warped from use? If your cookware isn't perfectly flat, it can be an incredibly inefficient way to cook. According to the Environmental Protection Agency, a "warped-bottom pot could take 50% more energy to boil water" versus a flat one. And when it comes to baking, choose glass or ceramic dishes. They heat up faster than metal, which means you can bake, roast and cook things at temperatures 25 degrees lower.
