ENERGY STAR certified computers deliver substantial savings over standard models. Desktops, integrated desktops, notebook (laptop) computers, workstations, small-scale servers, and thin clients are all eligible to earn the ENERGY STAR, and those that do are now more efficient than ever.
EPA has strengthened the requirements for computers earning the ENERGY STAR in Version 6.0. For desktops, integrated desktops, thin clients and notebook computers, products must meet stringent TEC (typical energy consumption) requirements for estimated annual energy consumption. Workstations must meet maximum power consumption requirements. Small-scale servers must meet energy use guidelines in "off" and "idle" modes of operation. To ensure energy savings when computers are being used and performing a range of tasks, as well as when they are turned off or into a low power mode, ENERGY STAR certified computers must also have efficient internal or external power supplies.
If all computers sold in the United States were ENERGY STAR certified, the savings would grow to:
- More than $1 billion in annual energy costs per year
- Approximately 15 billion pounds of annual greenhouse gas emissions, equivalent to the emissions from more than 1.4 million vehicles.

Power management is important to saving energy, especially since computers are often in use more hours per day than they used to be. ENERGY STAR power management features place computers (CPU, hard drive, etc.) into a low-power "sleep mode" after a designated period of inactivity. Simply hitting a key on the keyboard or moving the mouse awakens the computer in a matter of seconds. Activating power management features on your computer is easy. In addition, make sure you check with your IT manager at work to ensure “sleep settings” are activated to save up to $35 per computer annually at work as well. See how your organization can receive technical support and earn recognition from EPA for power managing computers organization-wide.
