Cut Data Center Energy Costs Without Green Tech

Loraine Lawson

Earlier this week, I blogged about a panel's predictions that we'd soon see the invention of a no-cool data center. But a recent report from the EPA shows there are steps companies could take now to reduce the environmental impact of data centers, according to this Associated Press article, published Wednesday on


Yet, when a California utility offered cash incentives to data centers if they'd reduce their energy bills, very few companies took them up on the recommended changes. That's despite the fact some of the changes are remarkably simple and low-tech - such as using a server room layout that improves air flow or using outside air during the winter to cool the server room.


Some experts in this article say the problem is a lack of economic pressure. Since power costs are usually allocated by floor footage or staff numbers, IT gets off easy, even though it's small server rooms and data centers -- some of which require 40-50 times more power than an office space of the same size -- may be the ultimate energy hog.


But if IT's willing to address the issue, it could result in huge savings for the business. IBM believes it will cut $250 million in expenses, partly through reducing power costs by moving the work load of 16,000 internal servers to 30 mainframes.
