The feds rate the energy efficiency of everything from air conditioners to dishwashers—and now you can add computer servers to the list. The U.S. Environmental Protection Agency (EPA) this week announced new Energy Star ratings for servers, a move designed to up average energy efficiency by 30 percent.
The program is part of a larger government initiative to green data centers, which used more than 60 billion kilowatt-hours—at a $4.5-billion price tag—in 2006, the EPA noted in a report to Congress the following year. In the wake of the findings, the Bush administration EPA pledged to craft a plan to slice energy usage by 10 percent by 2011. If all the new servers sold in the U.S. were to comply with the new Energy Star specifications, server owners could save $800 million annually in energy costs—and the reduction in climate-change-causing greenhouse gas emissions would amount to taking a million cars off the road.
