On July 20th, ENERGY STAR’s new specifications for computers went into effect. Today I listened in on a Department of Energy conference call which discussed the new specifications, which are expected to save consumers and businesses more than $1.8 billion in energy costs over the next 5 years and prevent greenhouse gas emissions equal to the annual emissions of 2.7 million vehicles.

The new specifications include:

Use of energy efficient power supply. Desktops must use power supplies that are 80% efficient
Operate efficiently in Standby/Off, Sleep, and Idle modes. Desktops must use less than 2 W in standby mode
Include and enable power management features of the system and provide user education about these feature

Only about 125 desktops and laptops currently meet the new stringent requirements. The list of computers is available as an Excel spreadsheet. Of note, Apple currently does not have one computer that meets the new requirements.

Not too many desktops and laptops were able met the ENERGY STAR requirements because they were tough.

Consider this:

In order for new power supplies and PCs to meet the ENERGY STAR requirements, they must meet an 80% efficiency rating across all rated power output. This means that if the computer is running at 1%, 100% or any level in between, the power supply must reach a minimum 80% efficiency rating in order to get the label. This means that many high efficiency labeled power supplies will not meet this requirement. After all, if it only has 75% at a one quarter load, it fails to meet the guidelines.
