GREEN COMPUTING

“Is the study and practice of designing,

manufacturing, using, and disposing of

computers, servers, and associated subsystems

—such as monitors, printers, storage devices,

and networking and communications systems -

efficiently and effectively with minimal or no

impact on the environment“. It is also been

called as Green IT.

TO SUMMARIZE• Green computing is a novel and an

innovative trend in the world of computing which has minimum or no impact on the environment.

• Green computing has introduced a range of equipments and technologies which help in limiting the impact on the environment.

• Use of EUPs help in different aspects of the computing world help in recognizing the areas for improvement.

GREEN IT IS CONCERNED WITH

Energy Efficient IT Architecture

Advanced Power and Cooling

Integration with Building and Landscape

Architecture

Using IT to enhance environmental

education and responsibility

Using IT to save energy

WHY GREEN COMPUTING

computer energy is often wasteful

leaving the computer on when not in use (CPU and

fan consume power, screen savers consume power)

printing is often wasteful

many of us print out useless things for some sake

printing out partial drafts

for a “paperless” society, we tend to use more paper

today than before computer-prevalence

pollution

manufacturing techniques

packaging

disposal of computers and components

Toxicity

There are toxic chemicals used in the manufacturing of

computers and components which can enter the food

chain and water!

WHY GREEN COMPUTING

ENERGY USE OF PCS

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

electrical current to run the CPU,

motherboard, memory

running the fan and spinning the disk(s)

monitor (CRTs consume more power than

any other computer component)

printers

Energy use comes from

DISPOSAL

183 million computers were sold in 2004 (674 million

cell phones!)

New users in China (178 million by 2012) and India

(80 million by 2012) will require the creation of new

computers

Disposal of these devices constituted 20-50 million

tons per year (about 5% of the total waste of the

planet)

this waste is called e-waste

where are we going to put all of it?

LAND FILLS

Europe has outlawed using landfills for

computer components the US and Europe export a lot of e-waste to

Asian landfills (especially China even though

China has outlawed the importing of e-waste)

in addition, incineration of computer

components leads to air pollution and airborne

toxins

PRACTICES TO BE FOLLOWED

Putting down the CPU and all peripherals during extended periods of inactivity to reduce the energy consumption.

Performance of computer-related tasks during contiguous, intensive blocks of time, leaving hardware off at other times to improve the efficiency in the work by saving the energy.

Powering-up and powering-down all the energy-intensive peripherals such as laser printers according to need to reduce energy consumption.

Usage of notebook computers in the place of desktop computers whenever possible to enhance cost reduction and energy savings.

PRACTICES TO BE FOLLOWED

Usage of liquid-crystal-display (LCD) monitors instead cathode-ray-tube (CRT) monitors not only decrease the energy consumption but also to improve the efficiency of work and hence the cost reduction also takes place.

power-management features to turn off hard drives and displays after the set minutes of inactivity.

Minimize the use of paper and adapt proper recycling method of waste papers.

The e-waste is to be disposed in the proper way according to federal, state and local regulations to avoid toxic pollutions.

GREEN BUILDINGS

Reduces the total ownership cost of facilities

Improve energy efficiency and water

conservation

Provides safety, healthy and productive built

environments

Promotes sustainable environmental

stewardship

GREEN BUILDING MODEL

CONCLUSIONS

Green IT

IT is a major power consumer

A significant percentage of the power is wasted

Opportunities exist to dramatically improve IT energy efficiency

IT can be a very beneficial part of the Green movement .

Recycle - Donations

Make sure your system has the correct OS license. Windows Genuine hologram label, MacOS, or alternative FOSS OS like Linux.

Donate with original media and documentation.

Wipe the hard drive with utility like DBAN. Do not format as it does not remove data only the table of contents.

17

Recycle – Dispose

o Wipe your hard drive with DBAN or comparable tool.

o Batteries can be recycled at many stores.o Electronics drives sponsored by local

municipalities.o Wake County hazardous materials drop off

o Location and hours:9029 Deponie DrRaleigh NC 27614Mon – Sat, 8am - 4pm

18

Reduce - Paper

eFAX – Send and receive faxes over the internet

Use both sides of paper. Save single sided sheets for reuse.

Add a duplexer to your printer or use duplex mode.

Shred and recycle paper that can no longer be used.

19

Reduce - PowerUse Energy Star approved electronics

Use OS power saving settings.• Turn off display• Stop hard drives• Have computer go into sleep or hibernate mode

Have computer go into sleep or hibernate mode when leaving the office for an hour or more.

Turn off devices in stand by mode at the end of day.

Unplug devices that have a remote control.

20

Reduce - PowerUse the class of device that balances power requirements with what you need to do.Less Power• Smart Phone• Tablet• Netbook• Notebook• Desktop replacement laptop• Desktop computer• Most server class computers

More PowerLaptops instead of desktop computers gives portability and reduces power usage. Most desktops are 250W+, most laptops are 65-90W.

21

Reduce - Power

The monster file server. Most business servers are used to store and serve files. Most servers are over powered for this simple task.

Server used at my home: File server, name services, audio streaming. Powered by Via C9 processor. 12W idle, 37W max.

Home DVR server: TV recording, playback, and streaming. 40W at idle, 58W max.

Consider using network attached storage instead of a file server. Seagate BlackArmor NAS uses 15-20W and is available at staples.com.

22

Reduce Dependence

Consider local point power generation.

30% tax credit for solar heat or photovoltaic systems.

Most systems will still require 7-12 years for break even.
