Presentation Transcript

GREEN COMPUTING : 

GREEN COMPUTING

Slide 4: 

Green computing is the environmentally responsible use of computers and related resources

Slide 5: 

NEED

1. computer energy is often wasteful : 

1. computer energy is often wasteful leaving the computer on when not in use (CPU and fan consume power, screen savers consume power)

Slide 8: 

CPU uses 120 Watts CRT uses 150 Watts 8 hours of usage, 5 days a week = 562 KWatts if the computer is left on all the time without proper power saver modes, this can lead to 1,600 KWatts for a large institution, say a university of 40,000 students and faculty, the power bill for just computers can come to $2 million / year

2. printing is often wasteful : 

2. printing is often wasteful how many of you print out your emails or meeting agendas printing out partial drafts for a “paperless” society, we tend to use more paper today than before computer-prevalence

3. pollution : 

3. pollution manufacturing techniques Packaging disposal of computers and components

4. toxicity : 

4. toxicity LEAD It is estimated that between 1997 and 2004, 1.2 billion tons of lead was used in computer components The problem: cause damage to the central and peripheral nervous systems, blood system, kidneys, endocrine system and cause negative effects on child brain development lead accumulates in the environment and has toxic effects on plants, animals and microorganisms

Slide 12: 

MERCURY is used in batteries, switches, housing, printed circuit boards The problem mercury spreads out in water transforming into methylated mercury which easily accumulates in living organisms it enters the food chain through fish that swim in polluted waters methylated mercury can cause chronic brain damage

Land Fills : 

Land Fills Europe has outlawed using landfills for computer components the US and Europe export a lot of e-waste to Asian landfills

THREE SUGESTIONS : 

THREE SUGESTIONS Power Management E-Mail Online

POWER MANAGEMENT : 

POWER MANAGEMENT Keep computers and PCs turned off ,when not in use. Disable screen saver. Don’t print unless necessary and you are ready Use LCDs instead of CRTs as they are more power efficient

Slide 16: 

Use hardware/software with the Energy Star label Energy Star is a “seal of approval” by the Energy Star organization of the government (the EPA)

Slide 17: 

Set low power “sleep” mode - can still download and perform other routines There are two basic options for putting your laptop to sleep when you're not actively using it, but don't want to completely shut it down—Standby or Hibernate.

Standby : 

Standby Standby is energy conserving, because your entire computer switches to a low-power state. Devices, such as the monitor and hard disks, turn off and your computer uses less power

HIBERNATE : 

HIBERNATE Hibernate mode writes an image of what you're currently working on to a special file on your hard drive, and then shuts your computer almost completely off

E-MAIL : 

E-MAIL Use e-mail to reduce paper work. Add: *Please consider the environment : Do you really need to print this e-mail? Put entire message in subject line(“eom”).

On-Line : 

On-Line Increase use of Internet and your Website. Place information on Web pages, wikis, blogs instead of making paper copies. Online courses consume nearly 90% less energy and produce 85% fewer CO2 emissions

Slide 24: 

Printing Savings

One More Solution: Recycling : 

One More Solution: Recycling If companies can recycle the plastics and other components, this can greatly reduce waste and toxins Developed countries now have facilities for recycling e-waste

How Do the Companies Rate? : 

How Do the Companies Rate? 8: Nokia - regained its top position for eliminating the worst chemicals from many products still needs to report on its recycling rate percentage 7.3: Dell - still among the top but loses points for not having models free of the worst chemicals strong support for global take back 7.3: Lenovo - dropping down the rank for not having a clear global take back program still missing out on products free of the worst chemicals on the market 7: Sony Ericsson - among the top with clear timeline to have products free of the worst chemicals by 2008 need better chemicals take back reporting program

FINAL QUESTION : 

FINAL QUESTION When do you need to start walking the talk on green computing? A. As soon as u get back to work B. Tomorrow C. Next Monday D. Today E. Not sure When do you need to start walking the talk on green computing? A. As soon as u get back to work B. Tomorrow C. Next Monday D. Today E. Not sure

Slide 28:
