If you have ever shopped for a new appliance or home device, you have probably seen the blue Energy Star label. But what does it really mean? And how does it help you save money or reduce your electricity use?
This guide breaks down what Energy Star ratings are, how they work, and how they can support smarter energy choices in your home.
What is the Energy Star program?
Energy Star is a government-backed symbol for energy efficiency. It was launched in 1992 by the U.S. Environmental Protection Agency (EPA) and is now used on thousands of products, homes, and buildings. The goal is to help consumers choose items that use less energy without giving up performance.
When you see the Energy Star label on a product, it means that item meets strict energy efficiency standards set by the EPA. These standards are based on product category and performance testing.
How does a product earn the Energy Star label?
To qualify, a product must meet several key criteria:
- It must offer significant energy savings compared to standard models
- It must deliver the same or better performance
- The energy savings must be measurable and verified through testing
- If the product costs more than standard models, it must help recover the difference through savings on utility bills
All Energy Star products are tested and certified by approved labs before they receive the label. The EPA reviews and updates requirements regularly to reflect improvements in technology and usage patterns.
What types of products carry Energy Star ratings?
Energy Star covers more than 75 product categories. Some of the most common items you’ll find in homes include:
- Refrigerators and freezers
- Dishwashers
- Washing machines
- Dryers
- Air conditioners
- Televisions
- Computers and monitors
- Light bulbs (especially LEDs)
- Smart thermostats
- Ceiling fans
Even entire homes and commercial buildings can earn the Energy Star label if they meet efficiency standards for insulation, ventilation, windows, and HVAC systems.
How do Energy Star ratings affect energy savings?
Energy Star rated products use less electricity than standard models. The exact savings depend on the item and how often it is used, but here are a few examples:
- Refrigerators with the Energy Star label use about 10 to 15 percent less energy than non-rated models
- Washing machines use around 25 percent less energy and 30 percent less water
- LED light bulbs with the Energy Star label use up to 90 percent less electricity than traditional bulbs
Over time, these savings can reduce your energy bill by a noticeable amount, especially when multiple rated products are used throughout your home.
Are Energy Star products worth the cost?
In many cases, yes. While some Energy Star products cost more up front, the savings over time can make up the difference. The label is designed to identify options that offer strong long-term value, not just lower electricity use.
Before buying, check the yellow EnergyGuide label that often appears alongside the Energy Star symbol. It provides an estimated yearly operating cost and a comparison to similar models, giving you a better idea of potential savings.
How can Energy Star support your energy goals?
Choosing Energy Star rated appliances and devices is a simple way to reduce energy waste without changing your habits. You do not need to use less—you just use smarter equipment.
For customers looking to improve their home’s efficiency or lower their monthly bills, Energy Star is a trusted guide to better decisions. From lighting upgrades to large appliances, this label helps remove guesswork from your purchase.
