2.3 Twelve Questions around Green IT.

13

2.1 Timeline of Green IT.



In 1992, the U

.

S

.

Environmental

Protection Agency launched

“Energy Star”.

14

Timeline of Green IT (Cont.)

15




Energy Star is a voluntary labeling program which is designed to promote and recognize energy-efficiency in monitors, climate control equipment, and other technologies.



This resulted in the widespread adoption of sleep mode among consumer electronics.

16




The term

“green computing” was probably coined shortly after the Energy Star program began.



There are several USENET posts dating back to 1992 which use the term in this manner.

17




Concurrently, the Swedish organization

“TCO (Tjänstemännens Central

Organization)” launched the

“TCO Certification program” to include criteria on energy consumption, ergonomics, and the use of hazardous materials.

18




Many governmental agencies have continued to implement standards and regulations that encourage green computing

.

19




The Energy Star program was revised in October 2006 to include stricter efficiency requirements for computer equipment, along with a tiered ranking system for approved products

.

20




U.S. States have established state-wide recycling programs for obsolete computers and consumer electronics equipment.

21

2.2 Benefits of Green IT.

1) Reduce travel time and cost.

2) Help customer reduce environment burden.

3) Save money for buying computer component.

4) Inspire employees.

22

1) Reduce travel time and cost.



Gartner Dataquest estimates that 25% of US employees worked from home, at least once a week in 2007 ,

European levels seems to be comparatively higher.

23

Reduce travel time and cost (Cont.)



Another study estimates that

33 million Americans are employed in roles suitable for telecommuting; removing these commuters from daily travels could drive down oil imports by 25% and reduce carbon emissions

.

24

2) Help customer reduce environment burden.



There is a

“New Green Policy Innovation” project from Fujitsu



This project aims to achieve a cumulative reduction of more than 7 million tons of CO2 from fiscal 2007 through fiscal 2010.

25

Reduce environment burden (Cont.)



The Fujitsu project will reduce the environment burden of IT infrastructure through and entire data centers that utilize such technology.

26

Reduce environment burden (Cont.)



In addition, the Fujitsu project will reduce customer’s environment burden through the introduction of new IT applications, including outsourcing and consulting services.

27

3) Save money for buying computer component.



Green IT will save a lot of money because using PC power management can cut energy costs by $20-60 per PC.



For many organization, this can mean a 5-15% reduction in overall , organization-wide energy consumption.

28

4) Inspire employees.



Employees feel a deep sense of pride working in organization that do their part for the environment.

29

Inspire employees (Cont.)



When employees know their computers are using less than half the power they used to, with no impact on productivity, they will know they personally are helping to reduce the company’s carbon footprint.

30

2.3 Twelve Questions around IT.



From www.cio.com.au/index.php/id;1236180095,

There are 12 questions and answers around green IT for CIOs to get with green.

31

12 questions around green IT (Cont.)

1. What is sustainable IT?

 Sustainable, or “green”,

IT is a catch

all term used to describe the manufacture, management, use and disposal of information technology in a way that minimizes damage to the environment

.



As a result, the term has many different meanings, depending on whether you are a manufacturer, manager or user of technology.

32


2. What is sustainable IT manufacturing?



Sustainable IT manufacturing refers to methods of producing products in a way that does not harm the environment

.



It encompasses everything from reducing the amount of harmful chemicals used in products

( such as lead and mercury

) to making them more energy efficient and packaging them with recycled materials

.

33


3. What is sustainable IT management and use?



Sustainable IT management and use has to do with the way a company manages its IT assets

.

It includes purchasing energy

efficient desktops, notebooks, servers and other IT equipment, as well as managing the power consumption of that equipment

.



It also refers to the environmentally safe disposal of that equipment, through recycling or donation at the end of its lifecycle

.

34


4. What is sustainable IT disposal?



Sustainable IT disposal refers to the safe disposal of IT assets

.

It ensures that old computer equipment does not end up in a landfill, where the toxic substances it contains can leach into groundwater, among other problems

.



Many of the major hardware manufacturers offer take

back programs, so IT departments don't have to take responsibility for disposal

.

35


5. What is the goal of sustainable IT?



The goal behind most green initiatives, including green IT, is to promote environmental sustainability

.



In 1987, the World Commission on Environment and Development defined sustainability as an approach to economic development that meets the needs of the present without compromising the ability of future generations to meet their own needs

.

36


6. What does it have to do with me?



No one seriously disputes that global warming is due to human activity

.

IT is an energy hog

.

Gartner estimates that power consumption by computers accounts for 2 percent of global carbon dioxide

(

CO2

) emissions

.



That's roughly equal to the carbon output of the airline industry

.

37


7. Can it help my company?



There are some steps IT departments can take toward becoming green that don't cost a lot

.

You can start by reminding your IT staff to turn off their PCs or shut off the lights before leaving for the day and championing such behavior companywide

.

38

Can it help my company? (Cont.)



Meanwhile, there are many IT investments you probably want to make anyway that will also reduce your impact on the environment

.

Virtualization technologies, server consolidation, PC power management and deployment of more efficient equipment when you do a refresh can reduce energy consumption while simultaneously improving

IT operations

.

39

Can it help my company? (Cont.)



There's some evidence that more people seek to do business with companies that offer green services and products, or that have a proven track record in corporate social responsibility

.

40


8. How can I cut my energy bills?



There are two ways that IT managers can help to reduce their companies’ energy consumption

:

- run data centers more efficiently

- manage desktops more efficiently

41


9. How can I make my data center more efficient?



The first step for CIOs who want to cut data center energy costs is to get to know their data centers in detail.



IT generally is unaware of how much energy it consumes running servers and air conditioners

.

42


10. How can I reduce my electricity consumption on the desktop?



CIOs can use the Electronic Product

Environmental Assessment Tool (EPEAT) developed by the Zero Waste Alliance to evaluate your purchases.



In the year 2008, six organizations, which were recognized for their use of

EPEAT, saved a total of over $5 million buying greener equipment

.

43


11. How do I recycle IT equipment?



There are a different ways to get rid of IT equipment without throwing it in the dumpster.



Many manufacturers offer take-back programs through which they assume responsibility for proper disposal.

44

How do I recycle IT equipment (Cont.)



Some companies that offer take

back services also offer data security services to insure that intellectual property and confidential information is removed from the hardware but the major companies involved in e

waste recovery

.

45


11. How can IT make my operations greener?



IT can help almost any part of the business lessen its environmental impact

.

For example, technologists can help reduce the amount of paper employees use for printing or deploy tracking systems to measure plant emissions

.

46

How can IT make my office greener

(Cont.)



IT systems can also help save energy by controlling heat and air conditioning in office buildings

- encourage green telework in the civil service

- address environmental behaviour in the

“Telework Guidance” document

202


take responsibility for the environmental impact of their employee's working patterns

look to sustainable computing models to reduce duplication of equipment between home and work

promote energy efficiency and the use of renewable energy in the home.

203




Recommendations to technology providers

:

- Products should minimise materials use from the outset

.

Miniaturisation can help, but this should not lead to greater proliferation of devices

- Product life needs to be extended

204


More advantage needs to be taken of mobile devices which use less energy and material resources than desktop PCs

-

“Network Computing” solutions should be considered as they may have smaller environmental impacts.

.

207

Timeline of Green Telework (Cont.)



The massive ongoing decrease in cost and increase in performance and usability of personal computers forged the way to decentralize even further, moving the office to the home.

208




By the early 1980s, these branch offices and home workers were able to connect to the company mainframe using personal computers.

209




The adoption of local area networks promoted sharing of resources, and client server computing allowed for even greater decentralization.

210




In the year 2008, teleworkers can carry laptop PCs around to use both at the office and at home

(and almost anywhere else)

211




Teleworkers are linked to their home office by using groupware, virtual private networks, and similar technologies to collaborate and interact with team members.

212




As the price of VPN-capable routers, high-speed Internet connections to the home, and VOIP technology has plummeted in recent years, the cost to connect a teleworker to their employer's intranet and telecommunications system has become negligible when compared with the operating costs of conventional offices.
