Energy efficiency guidelines modified for new computers

Washington, DC— The United States Environmental Protection Agency (EPA) announced new Energy Star specifications for computers and related equipment. These new modifications are also expected to prevent greenhouse gas emissions equal to the annual emissions of 2.7 million cars.

Under the new specifications, only the most energy-efficient computer related equipment will earn the Energy Star label, representing the top of their class.

The new requirements include improved efficiency across all modes of a computer's operation, and require use of highly efficient internal and external power supplies. The new specifications go into effect on July 20, 2007.

Government agencies buying Energy Star will also garner big savings. If the government sector buys only computers that meet the new Energy Star requirements, this sector will save nearly 1.4 billion kWh and reduce greenhouse gas emissions by 2 billion pounds each year.

On average, Energy Star qualifying computer equipment will be 65 percent more efficient than conventional models.

Computers were the first product to qualify for EPA's Energy Star in 1992. EPA and computer makers have worked together on improving computer energy efficiency ever since. The United States now has more 180 million computers in use; they consume nearly 58 billion kWh per year, or about 2 percent of annual electricity consumption.
