Energy Star ratings compare appliance efficiency to similar models. Higher ratings indicate better energy performance and lower operating costs.
ଷ୍ଟେପ୍-ଷ୍ଟେପ୍ ଗାଇଡ୍ |
- 1Appliances tested by EPA/DOE for standardized efficiency
- 2Must be top 15-25% most efficient to earn Energy Star
- 3Annual cost calculation helps consumer decision-making
ସମାଧାନ ହୋଇଥିବା ଉଦାହରଣ
ଇନପୁଟ୍
Refrigerator, Energy Star rated, 10% better efficiency
ଫଳ
Saves ~$100/year vs. standard, pays for cost difference in 5-8 years
Typical appliance
ଏଡ଼ାଇବା ଯୋଗ୍ୟ ସାଧାରଣ ଭୁଲ
- ✕Ignoring size differences (larger appliance uses more energy regardless of rating)
- ✕Not accounting for age replacement (old appliance less efficient than new standard)
