Hewlett-Packard Tuesday announced that it plans to reduce energy consumption of its personal computers by 25% within two years.

To reach its goal, HP said it will reduce energy usage by integrating energy-saving technologies and processes, like more efficient power supplies and lower-energy chipsets. The company plans on making the changes across its entire PC line.

HP announced the energy plans at the Consumer Electronics Show in Las Vegas.

The PC manufacturer noted that it now leads the industry in the number of Electronic Product Environmental Assessment Tool (EPEAT) Gold listed products with the introduction of more than two dozen PCs registered in North America at either the Gold or Silver rating levels.

"HP, for decades, has been integrating environmentally responsible components and processes across the entire product lifecycle," said Todd Bradley, an executive vice president at HP, in a statement. "We are dedicated to meeting our energy consumption goal of 25% reduction by 2010, and these additional EPEAT-Gold registrations exemplify how HP leads the IT market in reducing the environmental impact of its products and business processes."

In 2007, HP was the first PC manufacturer to register an EPEAT Gold product - the Compaq rp5700 Long Lifecycle Business Desktop PC.

The EPEAT system is designed to help shoppers evaluate and compare desktop systems, laptops and monitors based on the products' environmental attributes.

In March of 2007, HP tweaked three of its computers to meet the EPA's new Energy Star standard. The HP Compaq dc5700, dc5750 and dc7700 were updated to help business users reduce energy costs, primarily by switching into sleep or idle modes sooner than current models and by using an 80% efficient power supply instead of the current range of 65%-to-75% efficiency.
