If you're shopping for Energy Star appliances to reap some energy savings, you may have noticed that some appliances show a CEE Tier I, II or III. While this energy-related tier does not replace Energy Star, it does go one step further and denotes an appliance that is even more energy efficient. Why does it matter? An appliance that is both Energy Star compliant plus has a CEE Tier III, will save you the most in terms of electricity and water use.
