IT leadership understands the financial benefits of Green IT, which is why the top motivator for greener IT operations is financial. But the rolodex of Green IT projects available is seemingly endless. The data center itself is ripe with so much low-hanging fruit, that it’s not surprising organizations have been slow to moving Green IT efforts outside of it. And this could be a mistake given that recent Forrester research suggests more energy is consumed outside of the data center than within it – meaning that eco(nomic) benefits could be greater by, say, powering down PCs and monitors at night.


So how should IT pros prioritize Green IT investments? Forrester’s view is that before investing a single dollar, IT pros should first measure their Green IT baseline — an annual estimate of the energy consumption, carbon dioxide (CO2) emissions, and financial costs of operating your IT within and outside of the data center. Without this information, IT leadership is at best placing lucky bets on projects that will hopefully payoff, and at worst investing time and capital in less value-generating projects.


To begin your Green IT journey on the right foot, Forrester has created a free online calculator tool to help IT pros calculate their Green IT baseline.


IT is perennially challenged to reduce cost and do more with less, especially in today’s challenging economic climate. So when approaching Green IT, do yourself and your business a favor by investing your time and capital wisely by first measuring your Green IT baseline. Not only will this data offer a practical green IT starting point by exposing your most eco-taxing assets, but without it you cannot accurately quantify and report the benefits of your greening efforts to senior management.

  • use power management


    We at Emerson Network Power couldn?t agree with you more that 1 ? the drivers for going ?green? in IT are universally approved/declined on economic principles, namely ROI and very short payback and 2 ? the data center is an easy target due to IT asset density and presumed ease of project management. Yet as you so clearly noted, and I believe several third-party studies validate, quite often 2/3s to 3/4s of the enterprise network attached IT power consumption comes outside the data center.

    Your very simple suggestion of turning devices off or at the very least utilizing the resident power management feature would go a long way towards improving any companies bottom line. And given our current economic climate one would think that alone would be a sufficient incentive for action. If the resident power management function doesn?t get the IT folks excited then they could look to the likes of Verdium, 1E, and Cassatt for more sophisticated yet easily deployed tools.

    By the way that is one slick CO2 calculator tool you developed!

    Thank you driving home a point that we also feel is obvious ? if you aren?t using it turn it off!

    Best regards.

      What happens to the systems powered off while their user is on extended leave?

      They don't get patched, their AV definitions are not kept up to date or scanned periodically.

      So when these users come back and their FLASH is two version exploited and they instantly start hitting the web you have compromised systems.

      We are working on a multi-phase "Green IT" project starting with the monitors going into power save which reduces power by 15-60 watts per system (conservative estimate).

      Concurrent to that we are working on remotely provisioning the systems for Wake On LAN.

      When we have at least 80% on WOL then we will institute S3 (Standby mode) on all workstations with a directed packet (switched network here) wake-up.

      So if the system is in S3 standby it is consuming 4-8 watts (measured) then the management stations can wake them when attention is needed. It also allows us to wake up those systems that have been powered-off too.

      In that phase of the project we will have to decide whether we go back and power down those systems that were "awakened" or just let them stay on and go into S3 mode.
  • RE: How are you prioritizing Green IT investments?

    I'm gone green in 2 ways.
    1) not powering off crt's (using stand-by). The cold starting reduces their life substantially.

    2) Only upgrading gear that is dead because the system is good enough to run my business.

    That's green because there is no new "carbon deficit" attached for a new system. Sure it may use a couple tonnes more a year than the latest craze but its a few thousand tonnes less than the human labour carbon-cost, materials sourcing, manufacturing processing, and transportation. It's 100% reuse.
    What's more its massively cheaper!
