Network World's top 12 green IT products

However, Lawrence cautions that desktop power management benefits really don't start accruing for enterprises unless they've got at least a few hundred PCs. "But certainly if you have thousands of PCs you could be saving maybe a quarter of your energy use per PC," he adds. "Over the course of a year that would add up quite significantly with almost no downtime or cost at all to the company in terms of performance or availability."

In their own words:

"The average energy cost for all of [our] desktop computers per workday with no power management is about $2,090.88. The company is saving almost 50% of its daily energy costs and consumption by utilizing the power management feature."

"We save about $2 million annually in power costs while significantly decreasing the carbon footprint of our desktop operations."

Flat-screen monitors

What makes them green: Some of the biggest opportunities for green efficiencies lie outside the enterprise data center, Schulz says. "Monitors that use less energy but still provide a good picture and that automatically dim and have intelligent power management features built in can make a difference," he adds.

What's important is that accessories such as monitors don't get overlooked in the greening process, Schulz adds. "A lot of organizations perceive green as being only a certain set of things. They miss out by ignoring monitors, not thinking, 'Oh, if I change monitors I can get rebates and other incentives and, by the way, it'd be good for the environment."

According to Energy Star, if all monitors sold in the U.S. meet Energy Star requirements, energy savings could reach $1 billion each year and prevent greenhouse gas emissions equivalent to nearly 1.5 million vehicles.

Energy Star-qualified monitors must meet stringent requirements not only while on but also when asleep or powered off. In addition, IT buyers can look for monitors registered with EPEAT, a system for evaluating environmental attributes of electronic products, recommends Forrester's Washburn.

In their own words:

"Since 2008, we have been replacing CRT monitors with [IBM ThinkVision] flat-screen monitors, which provide better energy-efficiency, fewer materials used in manufacturing, less toxic components (e.g., CRT tubes contain toxic metals) and lower weight (reduces energy consumed in distribution)."

"It reduces our environment impact by lowering power consumption and it is partially made from recycled materials."
