Go Green!

Green computing, green IT or ICT Sustainability, is the study and practice of environmentally sustainable computing or IT. San Murugesan notes that this can include “designing, manufacturing, using, and disposing of computers, servers, and associated subsystems—such as monitors, printers, storage devices, and networking and communications systems — efficiently and effectively with minimal or no impact on the environment.”

The goals of green computing are similar to green chemistry: reduce the use of hazardous materials, maximize energy efficiency during the product’s lifetime, and promote the recyclability or biodegradability of defunct products and factory waste.

Many corporate IT departments have green computing initiatives to reduce the environmental impact of their IT operations. Green ICT and its services present opportunities to deliver low carbon footprints and mitigate carbon emissions because of the unique ability to make energy consumption and green house gas emissions visible through its products and services.

Why Green IT?

Because the world’s appetite for energy is outpacing production of renewable and non-renewable resources. Because the world is too densely populated to escape the effects of Greenhouse gas emissions, electronic waste disposal and toxic production methods. Because ICT is both part of the problem and a key to the solution. Because to thrive requires combining social responsibility, smart resource use and technological innovation.

Don’t get lost in the Greenwash

The overuse of “Green” may have you seeing red, but hype is a normal part of the evolution of new technologies. The issues driving the need for Green ICT are real, and growing.

ICT is the fastest growing sector of energy use

Global carbon emissions attributable to ICT have been estimated at 2% to 2.5% of world totals – about the same as the airline industry – and as high as 5-6% of developed nation totals. McKinsey forecasts that the ICT sector’s carbon footprint will triple during the period from 2002 to 2020.

For office buildings, ICT typically accounts for more than 20% of the energy used, and in some offices up to 70%.

Although energy costs typically comprise less than 10% of an overall IT budget, in a few years they could rise to more than 50% according to a 2006 Gartner report. Many large organizations – such as Google – already claim that their annual energy costs exceed their server costs.

Energy savings is the low-hanging fruit ready to be picked

Between 30% and 60% of the electricity consumed in server rooms is wasted – but integrated planning using current and emerging technologies can reduce power consumption in data centers by 50-80% and required floor space by up to 65%.

According to the Aug 2007 EPA Report to Congress on Data Center Efficiency, implementing best energy-management practices in existing data centers could reduce their current energy usage by 30%. Up to 70% reduction in energy usage could be achieved by using high efficiency technologies for cooling and power equipment and virtualization techniques.

Customers shop for Green Supply Chains

Public and private sector procurement departments are incorporating Environmentally Preferred Purchasing (EPP) requirements into IT contracts. To do that requires Purchasing to work with both IT and Sustainability specialists to understand what is desirable and possible.

Major global corporations – Coca Cola, Sharp, BT, to name a few – have launched programs to evaluate the life-cycle environmental footprint of products they sell and assess the environmental policies of their suppliers. Communicating and educating suppliers on expectations is a basic part of any sustainable supply-chain initiative.

Often, companies get compliance from their supply chain by enforcing adherence requirements. Examples of these are the requirements to use less material, to use post consumer recyclable content, and to purchase all packaging materials from certified forests.

EPP – Environmentally Preferred Purchasing – Sets the Bar

EPP policies are now routinely included in RFPs from Federal, State and local agencies and from corporations. Many RFPS require or give preference to vendors that meet Energy Star or EPEAT guidelines. A product supplier’s proposal can be entirely excluded from consideration for a government RFP if the products do not meet the relevant criteria.

In 2007, the US Government, which purchases $63B worth of electronic equipment every year, issued a Federal Electronics Challenge (FEC), instructing its agencies and facilities to purchase greener electronic products, reduce the impact of the ones it used, and dispose of obsolete products in an environmentally safe way. As a result, by 2008, 95% of computers purchased by FEC partners will be EPEAT Bronze-certified or higher and 100% of computer monitors purchased will be Energy Star compliant.

Customers Demand Sustainable Behavior

Corporate Social Responsibility reports are increasingly expected of companies. Sometimes, as in the case of the Carbon Disclosure Project, companies are asked to produce such a report of the same comprehensiveness and attention to detail as their financial reports.

ISO 14000, a specification for establishing environmental policy and determining the impact of a company’s products, activities and services, was adopted by the EU in 2001. It establishes standards for environmental auditing, labeling and life cycle assessment. Enterprises certified to ISO 14000 demonstrate commitment to Green policy.

With a mind toward increasing brand equity, Dell recently announced its intention to be the “greenest computer company on earth”, an initiative that puts it in competition with Hewlett-Packard for the same high ground. Other companies adopting similar mantles include IBM, Sun Microsystems, and AMD, to name a very few.

In 2006, WalMart, the world’s largest retailer, adopted a directive for Ethical Sourcing. Which required all its suppliers, among other practices, to provide a healthy environment for their workers, to strictly follow fair labor laws, and to use nontoxic materials.

Green IT innovation leads the way to Sustainability

Radical improvements in waste reduction and energy use rely on innovative applications of information technology:

  • Telework can reduce not only automobile travel but overall energy use by reducing the amount of dedicated office space.
  • Smart energy applications adjust energy consumption to real time need patterns and climate conditions, resulting in drastic reductions in waste.
  • Virtualization can eliminate wasteful network equipment, reducing energy and floorspace.

5 Tips for Green IT:

Trends in Green IT:

Conclusion

So far, consumers haven’t cared about ecological impact when buying computers, they’ve cared only about speed and price. But as Moore’s Law marches on and computers commoditize, consumers will become pickier about being green. Devices use less and less power while renewable energy gets more and more portable and effective. New green materials are developed every year, and many toxic ones are already being replaced by them. The greenest computer will not miraculously fall from the sky one day, it’ll be the product of years of improvements. The features of a green computer of tomorrow would be like: efficiency, manufacturing and materials, recyclability, service model, self-powering, and other trends. Green computer will be one of the major contributions which will break down the ‘digital divide’, the electronic gulf that separates the information rich from the information poor.
