IDG News Service (Seattle Bureau) — A group of some of the biggest technology companies said they've committed to a plan to improve the power efficiency of equipment they make and use.
The Climate Savers Computing Initiative, which includes companies such as Google, Microsoft, Intel, Hewlett-Packard, Dell and Sun Microsystems, aims to improve the efficiency of power sources for computers and servers and encourage end users to take advantage of underused power management techniques.
Only about 50 percent of the power that leaves a power outlet reaches a PC, because inefficient power cords leak energy, Google's senior vice president of operations, Urs Holzle, said Tuesday during a press conference to announce the program.
Climate Savers has defined a series of standards for power supply efficiency in servers and PCs that it suggests members adopt between now and July 2010. By 2010, the Climate Savers standard will define a power supply that is above 95 percent efficient, Holzle said.
The program asks manufacturing members to build products to the standard and companies to pledge to buy products that have the improved power supplies.
The improvement doesn't require the development of new technologies. "This is all do-able today with technology we have and know," Holzle said.
The reason that vendors haven't deployed such efficient power cords is that they cost more, said Pat Gelsinger, senior vice president and general manager of Intel's digital enterprise group. A PC with a more efficient power cord would cost about US$20 more and a server an additional $30, he said.
To address that price premium, Climate Savers is encouraging energy companies to issue rebates to users that buy products with the more efficient power supplies. Over time, that cost premium is expected to drop with volume production, Gelsinger said. In addition, end users will save on their energy bills, also helping to offset the cost, he noted.
Another component of Climate Savers is general education and encouragement for end users to take advantage of power management mechanisms that are typically built into existing PCs. "Ninety percent of PCs are capable but aren't utilizing power management techniques," Gelsinger said.
"We want to drive IT policy in enterprises," he said.
Improving power supply efficiencies and the use of power management techniques along the time line Climate Savers has described would reduce global carbon emissions from the operation of computers by 54 million tons per year. It would save 62 billion kilowatt hours of energy in 2010, worth about $5.5 billion in energy costs, the group said.
