The Enervee® Score. Actionable energy efficiency.

All current products.
Actionable comparisons.
Daily efficiency rankings.
Consistent across categories.
Shopping Integrated.


The Enervee Score helps you to find the most energy efficient products by translating product performance and energy use into a universal 0 to 100 (ideal) score. The Enervee Score is dynamic, meaning that it is updated daily for all products based on the range of products currently available on the market. If Samsung or Sharp releases a more energy efficient range of OLED TVs next week, the Enervee Score of all existing models will be pushed down to account for the expanded the range of TV efficiency.

The higher the Enervee Score, the more energy efficient and therefore less energy a product uses for its size/capacity/performance. We have broken the Enervee Score into four energy efficiency levels:

  • Not Good (1 to 50)
  • Good (51 to 75)
  • Very Good (76 to 90)
  • Ideal (91 to 100)

This easy scoring methodology helps you to quickly identify the best products via a comparison of thousands of appliances and electronics across thousands of products, such as TVs, Refrigerators, Freezers, Washing Machines, Dryers, Dishwashers, ACs, etc. The Enervee Score is updated daily and seamlessly integrated with the product listing to enable sorting or filtering on energy efficiency, cost, and other features while shopping.

Calculating the Enervee Score

The Enervee Score is calculated based on how much more or less energy a product uses compared to all others of the same size/capacity/performance. Below, we have provided the key attributes used for calculating the Enervee Score for each product category:

Televisions screen size (diagonal in) and kWh/yr
Refrigerators capacity (ft3) and kWh/yr
Freezers capacity (ft3) and kWh/yr
Projectors lumens of brightness and kWh/yr
Clothes Washers cubic feet of volume per kWh per cycle
Dishwashers cycles per kWh
Clothes Dryers pounds of clothes per kWh
Tablets performance (screen size & pixels, processing power and battery life) and kWh/yr
Video Game Consoles performance (CPU speed, memory and hard drive capacity) and kWh/yr
Air Conditioners BTUs of cooling power per watt
Monitors screen size (diagonal in) and kWh/yr
Light Bulbs lumens of brightness and Watts

Enervee follows industry standards on performance and energy efficiency ratings from the Department of Energy. For categories that are not regulated by the DOE, such as video game consoles or tablets, we have collaborated with key stakeholders to develop our own energy efficiency rating methodologies.
