How Well Do You Know Green It?<\/strong><\/p>\n

The Wall Street Journal – Monday, November 16, 2009<\/strong><\/p>\n

Technology has transformed the office, made it possible to communicate instantly around the globe and put the world’s art, music and books at our fingertips. Can it now help improve the environment? Technologists say yes, as they use computing power to save energy, reduce waste and produce power more efficiently. Try our quiz to see how well you know green IT. <\/p>\n

1) Which of these roles for information and communications technology has the potential to yield the biggest reductions in greenhouse-gas emissions by 2030?
A. Retrofitting existing buildings
B. Designing new buildings for reduced emissions
C. Telecommuting and virtual meetings
D. E-commerce and replacing paper
Answer: D. According to a study by the World Wildlife Fund, a big increase in online shopping and in the use of electronic transactions and documents to replace paper bills and publications could eliminate nearly a billion tons of greenhouse gases a year from the environment. That’s about twice the reduction estimated to result from either making existing buildings more efficient or designing new buildings that constantly monitor and adjust air conditioning and heating to minimize waste. More telecommuting and virtual meetings would save about 160 million tons of emissions a year, it estimated.<\/p>\n

2) Toyota Motor Sales cut energy use in its Torrance, Calif., data center by 10%. How did it manage that?
A. It stopped keeping track of dealer sales, shutting down four blade servers.
B. It moved all storage to an Amazon.com cloud-computing center.
C. It redirected air flow from air conditioners and separated intake and outflow ducts.
D. It planted heat-absorbing vegetation on the roof.
Answer: C. The Toyota Motor Corp. unit hired International Business Machines Corp. to analyze air flows in the building and their effect on temperature. Air flows can create uneven temperatures in a facility, which results in inefficient temperature control&mdash for instance, bringing hot spots down to the desired temperature takes more cooling than is necessary for the rest of the space. By changing the air-flow patterns, Toyota was able to cut its air-conditioning use.
3) Lithium-ion batteries are the most popular technology for laptops and cellphones, because they are light and long lasting. They also can be disposed of with little environmental impact. What country produces the most lithium?
A. Argentina
B. Bolivia
C. Chile
D. Denmark
Answer: C. Sociedad Quimica y Minera de Chile SA is the world’s largest lithium miner, with mines in Chile and in Argentina, the No. 2 producing country. Bolivia is considered a promising prospect for future development. <\/p>\n

4) Match the product, service or initiative with the company that dreamed it up.
A. Dell 1. ecoMeter
B. CA 2. Plant a Tree
C. Lexmark 3. Eco Ultra Small
D. Lenovo 4. Eco-simulator
Answer: A-2. Dell Inc. will plant a tree for each corporate laptop sold under some sales plans. It says each tree will soak up enough carbon dioxide over its projected 70-year life to offset the carbon used in making and powering a computer.
B-1. CA Inc.’s ecoMeter is software that helps chief information officers visualize, monitor and manage the use of energy in data centers and other facilities.
C-4. Eco-simulator is Lexmark International Inc.’s online service that measures the environmental impact of a user’s printing.
D-3. Lenovo Group says its M58p Eco Ultra Small desktop contains 10% recycled plastic.<\/p>\n

5) What is a zombie server?
A. One that causes so much trouble it is said to scare IT managers out of their wits.
B. One that is running but isn’t connected to any live data.
C. One that keeps running even though it has nothing to do.
D. A special server at Amazon.com that serves hit novels to teenage girls.
Answer: C. IT managers trying to understand why their data centers use so much electricity sometimes find that they have a number of servers that produce hardly any useful work. These servers sometimes were authorized for an ambitious sales campaign or other project that never achieved its goals but never was completely shut down. Such servers are good candidates for elimination, with their jobs to be taken up by other servers with computing power to spare. A study of four unidentified data centers by McKinsey and Co. discovered that 146 of 458 servers were running at less than 3% of capacity.<\/p>\n

6) What is the fastest-growing source of energy consumption in data centers?
A. High-end servers
B. Midrange servers
C. Networking devices
D. Storage devices
Answer: D. According to the Environmental Protection Agency, storage devices’ consumption of electricity grew 191% between 2000 and 2006. Over that period, storage devices rose from consuming the least power in the four categories to the most, at 32.3% of energy usage.<\/p>\n

7) What area of green technology is likely to offer IT veterans the most new job opportunities?
A. Smart grids
B. Solar-cell development
C. Engineering projects designed to fight global warming
D. Lithium battery development
Answer: A. A January 2009 report by Kema Inc., an energy consulting firm, estimated that in the U.S. alone, smart-grid development efforts could create up to 280,000 jobs directly by 2012. Jobs include installing smart meters in homes and designing software to manage the energy use of networks of homes and businesses more efficiently.
IT-networking skills match up neatly with smart-grid work, according to CleanEdge.com, a jobs Web site.<\/p>\n

8) Match the high-tech company with the organization that ranked it No. 1 in some aspect of environmental responsibility.
A. Hewlett-Packard 1. Greenpeace
B. IBM 2. Newsweek
C. Intel 3. Environmental
Protection Agency
Answer: A-2. Hewlett-Packard Co. took the top spot in Newsweek’s 2009 Green Rankings of the 500 largest companies in the U.S.
B-1. IBM was atop the &quot leaderboard&quot of Greenpeace’s CoolIT Challenge, due to &quot an extensive range of climate solutions and action to reduce its own emissions.&quot
C-3. The EPA said Intel Corp. was the biggest purchaser of renewable energy last year, accounting for 48% of its power.<\/p>\n

9) What percentage of corporate PC users leave their computers on nights and weekends when they aren’t in use?
A. About half
B. Hardly anyone
C. About 25%
D. Almost everyone
Answer: A. According to the nonprofit Alliance to Save Energy, less than half of corporate PC users shut their computers down overnight, even though they aren’t using them. Turning them off would save an estimated 20 million tons of carbon-dioxide emissions a year&mdash roughly equivalent to the impact of four million cars.<\/p>\n

10) What makes Windows 7 greener than Vista and other older Windows operating systems?
A. Microsoft prints the product manual on recycled paper.
B. It won’t run on high-energy microprocessors.
C. It reduces processor activity while the computer is idle.
D. It adjusts for intermittent power from wind turbines and solar panels.
Answer: C. It reduces background activity by electronically checking all connected devices at once and then going to sleep, rather than checking them at random times, which requires a central processor to be in operation almost constantly. It also reduces power consumption in other ways: It can be configured to stop searching for a network connection when a network cable isn’t plugged in. It suspends Bluetooth radio connectivity when it senses the Bluetooth device is in low-power mode. And it dims displays after shorter periods of inactivity than previous models. <\/p>\n
