The Green IT Stars of 2010

This year's crop of Green 15 winners demonstrates how organizations of all sizes are finding innovative ways to use information technology to achieve critical and often complementary environmental and business objectives.

This year's crop of Green 15 winners demonstrates how organizations of all sizes are finding innovative ways to use information technology to achieve critical and often complementary environmental and business objectives. Increasingly, companies are moving beyond out-of-the-box products and siloed approaches to making IT itself more energy efficient. Rather, they're leveraging technology as part of a broader, holistic effort to create greener operations as a whole.

Meanwhile, accounting company KPMG is finding ways to use IT to ingrain sustainable practices in day-to-day operations. For example, the company added a Green Travel Advisor to its internal portal that urges employees to use telepresence over air travel whenever practical. When it's not, the advisor directs them to environmentally responsible hotels.

Companies are also continuing to devise ways to enhance traditional green tech projects. In the past, data center greening projects tended to rely heavily on rolling out server virtualization, creating hot and cold aisles, and adjusting temperature and airflow. Green 15 winners including Dell and Intel have taken green data center initiatives a step further, employing homegrown techniques to drill down into how efficiently, or inefficiently, resources are being used and whether they're required at all.

Out of necessity or optimism, more organizations are thinking different in the name of thinking green. Syracuse University, for example, has done what few traditional data centers are willing to try: employing DC power in its new data center. The government of Andrha Pradesh in India embraced virtual desktops at 5,000 schools because it lacked the infrastructure for PCs. And a consortium of universities in Canada transformed a circular cement silo that formerly housed a particle accelerator into an innovatively designed cooling enclosure for a new supercomputer.

Since InfoWorld launched the Green 15 in 2008, project leaders have reiterated a shared sentiment time and again: Technology goes only so far in helping an organization achieve environmental objectives. Organizations in which executives work to promote green practices, engage employees, and drive collaboration and knowledge sharing among departments and business units will enjoy the greatest return on their green IT investments.

Aflac pushes for paperless practices, yields productivity gainsEmbracing electronic documents and print-management technology, the insurer sees faster policy processing and lower bills

Stacks of unclaimed printouts are a common site at organizations across the globe. At best, those pages get tossed into the nearest recycling bin, but even so, they represent a significant waste of natural resources and hard-earned company cash. As part of a companywide greening effort, insurance company Aflac instituted various technologies and policies to put the kibosh on print waste, resulting in a smaller environmental footprint, commendable cost reductions, and a surge in efficiency.

Starting last year, Aflac opted to invest only in energy-efficient network printers and has reduced printer count by 34 percent. Further, the IT department has set machines to default to two-sided printing, and the company embraced print management technology from Secureprint that requires users to confirm a print job at the printer before it will execute. Print jobs not retrieved within 24 hours are purged from the queue.

Aflac's paper-reduction efforts didn't end at the printer, either. The company's IT department has developed an online system called Smart App Next Generation (SNG) for enrolling and accessing policies electronically. "From a business perspective, this has helped Aflac reduce the need to handle the large amounts of paperwork usually associated with writing insurance policies. We are able to process the applications faster because there is no shuffling of paper between the agents and Aflac," said Pat Rayl, 2nd vice president of technology services at Aflac.

Agents have an added incentive to employ the environmentally friendlier approach to handling policies, Rayl noted: "Applications are approved faster through SNG. Therefore, the agents' commissions are paid faster."

The electronic delivery of policies, coupled with the electronic delivery of agents' statements, billing invoices, and corporate reports, has enabled Aflac to achieve an average of only 1.84 printed sheets of paper per active policy. There's also the ripple effect of fewer stacks of papers being sent to and fro via time consuming, eco-taxing snail mail.

Aflac's paper-reduction initiatives are a fraction of the company's overall sustainability initiatives. Other endeavors have included a data center makeover, such as server reduction through virtualization and improving cooling efficiency and air flow with techniques such as blanking panels, hot and cold aisles, and Koldlok around open floor areas. Additionally, the IT department has developed and promoted Aflac's Meeting Place, which features a suite of collaboration tools, including discussion groups, blogs, wikis, shared-document management, videoconferencing, and instant messaging. By promoting this approach to collaboration among offices spread out among its various offices and corporate campuses, the company saw a 43 percent increase in online meetings in 2009.

Rayl attributed the success of Aflac's multiple green endeavors to two key factors: sponsorship, promotion, and communication from upper management, as well as making the processes easy for employees to embrace. In terms of communication, Aflac's IT department maintains a Green IT page on Aflac Workplace that keeps company employees up to date on key metrics such as paper usage and server efficiency. "Probably the biggest lesson we have learned is that simply implementing green initiatives is not enough. Employees must be continually educated on the benefits of these programs and how they can contribute to making an environmental impact at work and at home," Rayl said.

Andhra Pradesh overcomes resource limitations with virtual desktopsWatt-sipping virtual PCs give students in India 5,000 school computer labs and a new start

For some organizations, embracing sustainability is something of a luxury. They have an ample supply of electricity, for example, and plenty of cash on hand, so they can gradually deploy waste-reducing projects that pay for themselves over time. For other organizations, however, sustainable efforts are driven by real, immediate needs.

Such was the case for the government of Andhra Pradesh in India, which needed to supply 1.8 million students across 5,000 public schools with access to state-of-the-art computing facilities. Standard desktop PCs wouldn't cut it, due to limited funding and limited electricity resources -- but virtual PCs proved a perfect alternative.

The school district chose a virtual desktop solution from NComputing. Students are equipped with their own monitor, keyboard, mouse, and NComputing X-series devices. (The devices come in kits that also include vSpace virtualization software and a PCI card.) The devices are connected to individual desktop computers, at a ratio of around 4 to 1, which perform the bulk of the processing work for the connected systems. In all, 40,000 NComputing devices were deployed, along with 10,000 full PCs provided by various OEMs, including HP and Acer.

The eco-magic of the NComputing access devices is that they require just a single watt of power to run, compared to a typical desktop that draws between 65 and 250 watts. Thus, the Andhra Pradesh government uses 90 percent less electricity than it would to power labs running traditional PCs. The virtual machines' watt-sipping nature was particularly significant given the limited infrastructure in the region.

"Certain locations where the installations occurred had very weak or no electricity infrastructure. For example, certain areas only received a few hours of electricity in the day. With a project of this scale, big generators would have been needed to support the setup of each lab in all of the 5,000 schools," said Stephen Dukker, CEO at NComputing.  "However, because of the low electricity consumption, the Andhra Pradesh government purchased smaller generators that are generally used in homes."

In terms of cost, the government estimates that taking the virtual desktop route conserved a whopping $20 million when factoring in savings on larger generators, fuel, electricity, and the like. From a green perspective, the virtual devices are also eco-friendlier than traditional PCs in that they last longer and contain fewer materials.

Thanks to the power of green technology, the students of Andhra Pradesh will be far better prepared for the future. "Earlier students did not even have an idea of how to switch on and off the computer," said Bhavani, a teacher at Zila Parishad School at Medak, India. "After four months, they are operating [the machines] themselves."
