Your Next Computer Will Be Green
By Marjie Tucker, Editor, Mountain Computer User Group, GA
With Europe leading the way, the computer industry is decidedly becoming "green." The Waste Electrical and Electronic Equipment (WEEE) and the Restriction of Hazardous Substances (ROHS) directives went into effect earlier this year. These two directives state that certain electrical and electronic equipment must cut down on hazardous materials such as lead, mercury, and cadmium. They also give customers the right to return their equipment free of charge. Companies have several years to fully implement these directives, but the leaders have already started to make changes.
Dell, for example, is advertising Energy Smart workstations and notebooks that can reduce power consumption by as much as 78%. The Energy Smart configuration uses a default power setting that is designed to reduce consumption and energy costs right out of the box. In addition, the power supply, fan, and motherboard use significantly less energy to maintain cool internal temperatures.
HP is using 80 Plus power supplies to lower energy bills and AMD technology that reduces heat output and PC power consumption. In addition, they have already introduced an HP recycling program where you can trade-in or donate the products.
Government Initiatives Many U.S. government agencies have implemented standards and regulations to encourage green computing. The Environmental Protection Agency launched an Energy Star program in 1992 and strengthened its requirements in 2006. In 2003 the California State Senate enacted the Electronic Waste Recycling Act and in 2007 President Bush issued Executive Order 13423 requiring all federal agencies to use the Electronic Products Environmental Assessment Tool when purchasing computer systems. In addition, a global consortium called The Green Grid was founded in 2007 by AMD, APC, Dell, HP, IBM, Intel, Microsoft, Rackable Systems, SprayCool, Sun and VMware.
Another initiative formed by a group of Global-minded IT executives, the Green Computing Impact Organization (GCIO), was created to be an active participant in transforming the IT community from an environmental liability to an Earth conscious example of responsibility. GCIO is a nonprofit organization that is based on environmental audit programs for consumers and small business homes with respect to general energy-efficiency programs (including lighting, heating, insulation, etc.). GCIO’s mission is to educate and assist enterprise technology users in the design of environmentally aware and responsible information system operations. They help consumers become more environmentally responsible by reducing energy consumption and electronic waste in an effort to protect the Earth.
GCIO is sponsoring educational programs across the country and participating in a Green Computing Summit that will be held in Washington, DC on May 20th. The summit will address how public sector IT managers, procurement officials, and program managers public sector professionals can transform their IT and data center operations into more environmentally conscious yet efficient solutions. This conference will attract senior government IT professionals and their industry partners tasked with helping agencies become greener in the coming years. Attendees will represent federal, state and local governments, public policy organizations and suppliers to government.

Features of Green Computing
Power management is the most popular method. The operating system of the computer can be set to directly control the power saving aspects of the hardware. It can automatically turn off the monitor or hard drive after a period of inactivity. Or, the entire system may hibernate, turning off most of the components such as even allow the user to manually adjust the voltages supplied to the CPU to reduce the electricity consumption and the amount of heat that is produced. As of July of 2007, all new Energy Star certified desktops must have a power supply that is at least 80% efficient.
Other features include using motherboard video output instead of a video card, hard disks that consume less power, flash based solid state drives that require fewer write cycles, and lower energy monitors. And, manufacturers of networking equipment are developing switches and routers that reduce energy costs.
Obsolete computers can be reused for charities, non-profit organizations, and developing countries. Parts from really old systems can be recycled through some recycling centers. Some recycling charges can be passed back to the manufacturers.
Recycling this equipment keeps the lead, mercury, and chromium out of our landfills. In addition, computer supplies such as cartridges, paper, and batteries can be easily recycled.
How Can We Work Greener?
Visit the website for Climate Savers Smart Computing at sww.climatesaverscomputing.org to view a three step program to go green. Here are the basic steps that they suggest:
Step One - Turn on Power Management. Since the average desktop PC wastes nearly 50% of the energy it consumes as heat, it makes sense to use the power management features that are built into Windows XP and Vista. The benefits? You will reduce your electricity bills and your energy footprint will be lowered as you reduce your greenhouse gas emissions. The Climate Savers organization predicts that the power management features on your computer can save nearly have a ton of CO2 and more than $60 a year in energy costs.
Step Two - Buy an energy efficient computer. Energy Star, the program designed by the U.S. Environmental Protection Agency, specifies the standards that equipment and appliances must meet to wear the Energy Star badge. You can visit their website at http://www.energystar.org for specifics. Basically an Energy Star compliant PC uses 15 to 25 percent less energy. This program is expected to save U.S. consumers and businesses more than $1.8 billion in energy costs over the next five years and prevent greenhouse gas emission equal to 2.7 million vehicles.
Step Three – Unplug from phantom power. As long as your computer is plugged in it still uses electricity, even while it is turned off or in standby mode. A computer that is turned off, but still plugged in, can use up to 10 watts. The Climate Savers estimate that you can reduce your electricity bills by as much as 10% by unplugging your appliances and electronics when they're not being used.
