Four months before regulators apply stringent new efficiency standards to desktop PCs, Hewlett-Packard has tweaked three computers to qualify for the US Environmental Protection Agency's (EPA) Energy Star 4.0 label.
The HP Compaq dc5700, dc5750 and dc7700 will help business users reduce energy costs, primarily by switching the machine into sleep or idle modes sooner than current models. They will also use an 80 percent efficient power supply instead of the current range of 65 percent to 75 percent efficiency, said Nancy Bowman, HP's commercial desktop product marketing manager for North America.
HP hopes the revamped computers will appeal to institutional IT managers who face a corporate requirement to meet efficiency standards, Bowman said. There are now 80 desktop models listed in the EPA's Electronic Product Environmental Assessment Tool Web site listing of "green" desktops that avoid toxic substances, are easily recycled and are energy efficient. But most of those desktops meet the EPA's current, lower standard, Energy Star 3.0.
In October 2006, the agency said it would upgrade that standard for the first time since 2000 because 98 percent of all products in the marketplace met its requirements. In an effort to give the Energy Star badge more elite status, regulators raised the bar so it would include only the top 25 percent most efficient desktops, notebooks, tablets, workstations, low-end servers, and game consoles. The new standard takes effect on 20 July and upgrades to an even tougher, Tier 2 standard in 2009.
PC and chip vendors are keen to be seen as environmentally sound.
On Wednesday, Dell said it would expand its "Plant a Tree for Me" programme, allowing all US-based consumers and businesses to offset the carbon emissions of manufacturing and running their IT products by contributing through Dell's Web site to several environmental groups.
Dell also plans to design several OptiPlex desktops, Latitude notebooks and Dell Precision workstations to meet the Energy Star 4.0 standard.
In other initiatives, Toshiba said last week that it submitted select notebook models to the EPEAT list and opened a [computer take-back program] to encourage recycling. Toshiba said it will help keep computers out of landfills by offering cash for used, functional PCs, recycling non-Toshiba notebooks for a small fee, and recycling its own brand products for free.
Also last week, Intel announced it would remove halogenated flame retardants from the packaging materials it used for its StrataFlash Cellular Memory (M18) products, a line of NOR flash memory units used in wireless handsets.
