We know that some computer hardware -- PCs and servers, for example -- are greener than others. They are built to be more energy efficient and easier to recycle, plus they use fewer hazardous materials. Certifications such as Energy Star and EPEAT make it easy to find at least some of those machines.

"Plug data leaks" and "Embrace Web 2.0" are among the pieces of practical wisdom shared this week by InfoWorld's Dan Tynan in an article titled "Seven things IT should be doing (but isn't)." It's a sound list, to be sure, but I believe there's an important omission. For the sake of your company's bottom line, its legislative peace of mind, its CSR (corporate social responsibility) standing, end-user morale, and yes, the planet as well, No. 8 on the list should be "Think green."

The prospect of disposing of old IT equipment -- PCs, servers, storage gear, and the like -- may very well fill your heart with dread. After all, you're putting a lot of faith in a third party that the machines will be thoroughly wiped of confidential information, resold for a fair price, and, when applicable, properly disassembled, recycled, and disposed of. If your partners' practices end up being sloppy -- or downright criminal -- you could find yourself in regulatory and PR hell as confidential data protected by HIPAA or SarBox ends up in the wrong hands or 500 of your PCs end up in a landfill or river somewhere.

For some datacenter operators out there, insufficient server processing power isn't driving them to adopt more and more servers. Rather, it's the lack of precious server memory, necessary to deliver results at the lightning speed users have come to expect -- nay, demand -- from search engines, social networking sites, e-commerce sites, and similar Internet-based applications. A pair of companies, Virident and Spansion, have announced a remedy to the problem: replacing (or, more accurately, supplementing) the traditional DRAM found on servers with a flavor of flash memory called EcoRAM, capable of boosting a single server's memory beyond today's 32GB limit to a capacity of 512GB -- without increasing the machine's power envelope.

When Energy Star 4.0 went into effect last year, it seemed to set a rather high bar for power supplies: In order for a computer to meet the standard, it needs a PSU with a minimum efficiency of 80 percent. But hardware vendor Dell already appears to have an eye on the next version of the Energy Star specification, which is slated to go into effect in July of 2009.

Interest in green technology is out there, but price remains the No. 1 barrier to wider-spread adoption, far more so than skepticism that green tech is really good for the environment. Those are among the survey findings released this week by Green Factor, a joint initiative between Strategic Oxygen, GCI Group, and Cohn and Wolfe aimed at "illuminating 'green' marketing opportunities and further[ing] 'green'-focused research on a global scale."

Organisations are investing in green computers -- that is, machines that are energy efficient and built in an environmentally responsible manner -- at ever-increasing rates. Sometimes they pay a small premium to do this. Is it worth it? They seem to think so.

Who should be responsible for your company's energy initiatives? Your organization may be grappling with the answer to that question. Controlling IT energy consumption has become a high priority for many companies as a way to lower costs, maintain business operations, and reduce their impact on the environment. It can be a rather daunting challenge, given that so many areas of a company's IT infrastructure -- from the desktop to the datacenter -- contribute to power usage, not to mention that various departments have vested and sometimes conflicting interests in those operations (for instance, users want might want more computing power -- but another department has to pay for it).

Imagine, if you will, that you're planning a brand-new datacenter. Ah, the excitement! The anticipation! But oh, the costs ... Yes, they're going to be high, but at least you're now in an enviable position: You can determine your realistic anticipated needs for your new datacenter, which in turn will help you calculate how expensive it will be to construct -- as well as to power and operate after it's complete.

Companies are becoming increasingly aware of the high costs of maintaining and cooling servers: A mid-tier $2,500 server can cost as much as $2,020 to power and cool annually, according to the Uptime Institute. Thus, demand for ways to curb those expenses is rising as well.
