Digital Diet Reading Answers

{A} Telecommuting, Internet shopping and online meetings may save energy as compared with in-person alternatives, but as the digital age moves on, its green reputation is turning a lot browner. E-mailing, number crunching and Web searches in the U.S. consumed as much as 61 billion kilowatt-hours last year, or 1.5 per cent of the nation’s electricity-half of which comes from coal. In 2005 the computers of the world ate up 123 billion kilowatt-hours of energy, a number that will double by 2010 if present trends continue, according to Jonathan Koomey, a staff scientist at Lawrence Berkeley National Laboratory. As a result, the power bill to run a computer over its lifetime will surpass the cost of buying the machine in the first place giving Internet and computer companies a business reason to cut energy costs, as well as an environmental one.

{B} One of the biggest energy sinks comes not from the computers themselves but from the air-conditioning needed to keep them from overheating. For every kilowatt-hour of energy used for computing in a data centre, another kilowatt-hour is required to cool the furnace-like racks of servers.

{C} For Internet giant Google, this reality has driven efforts such as the installation of a solar array that can provide 30 per cent of the peak power needs of its Mountain View, Calif., headquarters as well as increased purchases of renewable energy. But to deliver Web pages within seconds, the firm must maintain hundreds of thousands of computer servers in cavernous buildings. “It’s a good thing to worry about server energy efficiency,” remarks Google’s green energy czar Bill Weihl. “We are actively working to maximize the efficiency of our data centres, which account for most of the energy Google consumes worldwide.” Google will funnel some of its profits into a new effort, dubbed RE<C (for renewable energy cheaper than coal, as Google translates it) to make sources such as solar-thermal, high-altitude wind and geothermal cheaper than coal “within years, not decades, according to Weihl. .

{D} In the meantime, the industry as a whole has employed a few tricks to save watts. Efforts include cutting down on the number of transformations the electricity itself must undergo before achieving the correct operating voltage; rearranging the stacks of servers and the mechanics of their cooling; and using software to create multiple “virtual” computers, rather than having to deploy several real ones. Such virtualization has allowed computer maker Hewlett-Packard to consolidate 86 data centers spread throughout the world to just three, with three backups, says Pat Tiernan, the firm’s vice president of social and environmental responsibility.

{E} The industry is also tackling the energy issue at the computer-chip level. With every doubling of processing power in recent years has come a doubling in power consumption. But to save energy, chipmakers such as Intel and AMD have shifted to so-called multicore technology, which packs multiple processors into one circuit rather than separating them. “When we moved to multicore-away from a linear focus on megahertz and gigahertz—and throttled down microprocessors, the energy savings were pretty substantial,” says Allyson Klein, Intel’s marketing manager for its Ecotech Initiative. Chipmakers continue to shrink circuits on the nanoscale as well, which means a chip needs less electricity” to deliver the same performance, she adds.

{F} With such chips, more personal computers will meet various efficiency standards, such as Energy Star compliance (which mandates that a desktop consume no more than 65 watts). The federal government, led by agencies such as NASA and the Department of Defense may soon require all their purchases to meet the Electronic Product Environmental Assessment Tool standard. And Google, Intel and others have formed the Climate Savers Computing Initiative, an effort to cut power consumption from all computers by 50 per cent by 2010.

{G} Sleep modes and other power management tools built into most operating systems can offer savings today. Yet about 90 per cent of computers do not have such settings enabled, according to Klein. Properly activated, they would prevent a computer from leading to the emission of thousands of kilograms of carbon dioxide from power plants every year. But if powering down or unplugging the computer (the only way it uses zero power) is not an option, then perhaps the most environmentally friendly use of all those wasted computing cycles is in helping to model climate change. The University of Oxford’s ClimatePrediction.net offers an opportunity to at least predict the consequences of all that coal burning.

{H} CO2 Stats is a free tool that can be embedded into any Website to calculate the carbon dioxide emissions associated with using it. That estimate is based on an assumption of 300 watts of power consumed by the personal computer, network and server involved- or 16.5 milligrams of CO2 emitted every second of use. “The typical carbon footprint is roughly equivalent to 1.5 people breathing,” says physicist Alexander Wissner-Gross of Harvard University, who co-created the Web tool.

Supporting sentence: “When we moved to multicore-away from a linear focus on megahertz and gigahertz—and throttled down microprocessors, the energy savings were pretty substantial,”
Keyword : Allyson Klein, multicore-away, megahertz and gigahertz, throttled down microprocessors
Keyword location: paragraph E, lines 4-6
Explanation: Lines 4-6 of paragraph 6 says that Allyson Klein, marketing manager for Intel's Ecotech Initiative, claims that the energy savings were rather significant. It is significant when the company switched to multicore and away from a linear focus on megahertz and gigahertz. It also throttled down microprocessors. Circuits on the nanoscale are also continuing to be shrunk by chipmakers. This implies a chip uses less electricity to work at the same level, she continues.

Question 3: Targeting at developing alternative sources within the near future

Answer: D
Supporting sentence: Google will funnel some of its profits into a new effort, dubbed RE<C (for renewable energy cheaper than coal, as Google translates it) to make sources such as solar-thermal, high-altitude wind and
geothermal cheaper than coal “within years, not decades, according to Weihl. .
Keyword : Bill Weih, will funnel, new effort, make sources such as solar-thermal, high-altitude wind and geothermal
Keyword location: paragraph C, last line
Explanation: The last line of paragraph C suggests that in order to make renewable energy sources, some measures were taken. The renewable energy like as solar thermal, high-altitude wind, and geothermal more affordable than coal. Google will contribute a portion of its revenues to a new initiative called REC (for renewable energy cheaper than coal, as Google interprets it). This will happen "within years, not decades," according to Weihl.

Questio 7: To chill the server does not take up the considerable amount of energy needed for the computer.

Answer: FALSE
Supporting sentence: For every kilowatt-hour of energy used for computing in a data centre, another kilowatt-hour is required to cool the furnace-like racks of servers.
Keyword : every kilowatt-hour, computing in a data centre, cool the furnace-like racks of servers
Keyword location: paragraph B, last line
Explanation: Last part of paragraph B portrays that not the computers themselves has been mentioned. Also, the cooling equipment required to prevent overheating is one of the greatest energy consumers. In a data centre, cooling the furnace-like server racks consumes an additional kilowatt-hour for every kilowatt-hour needed for computation. Therefore, the given answer is regarded to be a FALSE one.

Question 8: It seems that the number of servers has a severe impact on the speed of the internet connection.

Answer: TRUE
Supporting sentence: But to deliver Web pages within seconds, the firm must maintain hundreds of thousands of computer servers in cavernous buildings.
Keyword : deliver Web pages, seconds, maintain hundreds of thousands, computer servers
Keyword location: paragraph C, line 2
Explanation: The paragraph C depicts that a solar array that can supply 30% of the peak power requirements of Google's Mountain View, California, headquarters was installed. Also, the company has boosted its purchases of renewable energy as a result of this reality. However, the company needs run hundreds of thousands of computer servers in enormous structures in order to provide Web sites in only a few seconds. Google's green energy czar Bill Weihl says that worrying about server energy efficiency is a good thing. Therefore, the above statement is a TRUE assertion.

Question 9: Several companies from other fields have a joint effort with the internet industry to work on ways to save energy.

Answer: NOT GIVEN
Supporting sentence: As a result, the power bill to run a computer over its lifetime will surpass the cost of buying the machine in the first place giving Internet and computer companies a business reason to cut energy
costs, as well as an environmental one.
Keyword : cost of buying, computer companies, business reason to cut energy costs
Keyword location: paragraph A, last line
Explanation: According to Jonathan Koomey, a staff scientist, the energy consumed by computers worldwide in 2005 was 123 billion kilowatt-hours. If current trends continue, this figure will double by 2010. As a result, computer and Internet firms will have a financial incentive to reduce energy expenses. In addition to an environmental one because the cost of operating a computer throughout its lifetime will exceed the cost of purchasing the device. Thus, the statement can be regarded as an invalid one, as no justified statement is given in the passage to support it.

Question 10: Actions taken at a governmental level are to be expected to help with savings in energy in the near future.

Answer: TRUE
Supporting sentence: The federal government, led by agencies such as NASA and the Department of Defense may soon require all their purchases to meet the Electronic Product Environmental Assessment Tool standard.
Keyword : The federal government, soon require, to meet the Electronic Product Environmental Assessment Tool standard
Keyword location: paragraph F, line 2
Explanation: Paragraph F states that a greater number of personal computers will be able to comply with efficiency criteria like Energy Star with the help of these chips. It mandates that a desktop consume no more than 65
watts. Government agencies like NASA and the Department of Defense may take some steps. They may soon demand that all federal purchases adhere to the Electronic Product Environmental Assessment Tool standard. So, the statement can be regarded as a TRUE one.
