Google and Intel are teaming up to introduce more energy-efficient personal computers and server systems to save energy and reduce greenhouse gas emissions. More efficient computing would reduce electricity consumption by eliminating wasted heat produced by computers and increased air conditioning to battle the heat problem.

Climate Savers Computing Initiative has alreadey signed ion Dell Inc., Hewlett-Packard Co., IBM, Lenovo Group Ltd., software maker Microsoft Corp., the U.S. Environmental Protection Agency.

The program will set new efficiency goals for computers and software tools that manage power consumption, namely, a 90 percent efficiency standard for power supplies, said Urs Holzle, senior vice president of operations at Google.

"Today, the average desktop PC wastes nearly half of its power and the average server wastes one-third of its power," he added.

A 90 percent standard would cut greenhouse gas emissions by 54 million tons a year and save more than $5.5 billion in energy costs.
