The green IT track at Interop Las Vegas kicked off with a session from yours truly on “The Evolution Of Green IT: Projects That Cut Cost, Avoid Risk, And Grow Revenues” to help IT professionals plan for green IT’s current and future state, backed up with a number of real-life examples. Here are the key takeaways that I&O professionals should pay attention to:
Consider the following: AT&T expects to save $12 million per year and 123,000 tons of carbon emissions per year using 1E's PC power management software to turn off PCs at night. By turning up the temperature in the data center from 69°F to 74°F, KPMG realized a 12.7% reduction in cooling energy usage. And Citigroup expects to save $11 million and 3,000 tons of greenhouse gases annually by simply enabling duplex settings on printers and copiers.
How are they achieving this? Green IT. Even in the face of a weak economy, Green IT is on the rise with approximately 50% of organizations globally enacting or creating a green IT strategy plan. And don't be fooled: green IT is as much about the greenbacks as it is about reducing the environmental impact of operating IT and the business. In fact, financial motivation — not environmental motivation — is the driving force behind the pursuit of greener IT (see Forrester’s “Q&A: The Economics Of Green IT”).
But despite the optimism, IT “blowhards” across the globe are negating the carbon reduction benefits of green IT one breath at a time. While virtualizing servers or powering down your PCs will reduce energy spend and CO2 emissions, Forrester finds that these jabber mouths — speaking fast, loud, and out of turn using unnecessarily wordy vocabulary — are creating a zero sum game.
To date, IT pros have given very little attention to the “greening” of the network. Why? Three words: follow the money. According to recent Forrester research, the top motivation for pursing Green IT is to “reduce the energy-related costs of operating IT.” And when compared to other IT energy-drawing assets – like servers, data center cooling or PCs – the energy consumption of the network falls at the bottom of the list, meaning that the ROI to reduce energy use is less compelling.
But the launch of Cisco’s EnergyWise technology is likely to raise the “greening” status of the network. EnergyWise is a free software upgrade to Cisco’s entire line of Catalyst switching gear. The technology allows customers to monitor, manage and ultimately reduce energy consumption of anything “connected” to the network. As Cisco describes, EnergyWise will evolve over three phases, adding new functionality with each iteration:
In the first phase (February 2009), Network Control, Cisco EnergyWise will be supported on Catalyst switches and manage the energy consumption of IP devices such as phones, video surveillance cameras and wireless access points.
In the next phase (Summer 2009), IT Control, there will be expanded industry support of EnergyWise on devices such as personal computers (PCs), laptops and printers.
The rolodex of Green IT projects available to IT leadership is seemingly endless. But at some point, prioritization is necessary, and IT professionals tend to gravitate to those projects that produce an acceptable financial return with the path of least resistance. And in recent interactions with Forrester clients, it's becoming clear that PC power management -- the act of powering down PCs when not in use (e.g. nights, weekends) -- is one of those projects IT leadership are willing to act on.
Do I agree? In short yes. And here’s why: PC power management can reduce costs, cheaply and effectively, while at the same time help justify more strategic IT investments and improve your green "credentials." Let me elaborate:
In a number of recent client interactions with both enterprise IT end users and vendors, the question of “Is the ‘green’ in Green IT dead?” has come up. Primarily driven by the current economic climate, IT end users want to understand how relevant the environmental benefits of Green IT should be to their strategic planning; likewise, vendors want to know how palatable green messaging of their products and services is to their customers.
In many of my recent interactions with both enterprise IT end users and vendors, the notion of calling Green IT something other than “Green IT” occurs with fair consistency. Some of the variations to Green IT that I’ve come across purposely call out an environmental agenda, i.e. Greener IT, Sustainable IT, and Eco-Efficient IT. While others are purely business such as Efficient IT, Energy Efficient IT, or Lean IT.
Yes, but the shade of green will vary. While it’s clear that the next generation data center will be an energy efficient data center, incorporating other green data center features — from reduced water usage, to sustainable site planning, to sourcing IT gear manufactured in a more eco-responsible fashion — are not likely to happen at the same pace.
Why? Reduced energy consumption in the data center offers tangible and immediate environmental and economic savings, but also goes hand-in-hand with alleviating out of space and out of power concerns — challenges, that for now, trump purely green motivations.
At last week’s annual Next Generation Data Center Conference held in San Francisco, I had the opportunity to discuss the role of “green” in the data center by moderating a panel on the topic of “Greening of the Data Center — Practical Steps That Can Be Implemented Today With Real World Savings.” The panel consisted of major industry hitters — including Jack Pouchet of Emerson Power Network, Joe Prisco of IBM, Michael Patterson of Intel, Christian Belady of Microsoft, and John Pflueger of Dell — with all panelists having a stake in enacting green and or energy efficiency strategies within their organizations. Here are some key takeaways from the session:
