Why is Green Computing required?

" Computer consumes a lot of energy.

" Reduce unnecessary printing results

(reducing the paper)

" Reduce po l lu t ion ( reduc ing t rave l

requirements for employees or costumers)

" Reduce the power consumption

" Reduce the global warming

" Reduce use of toxic materials.

Overview of Green Computing “Greening” your computing equipment is a low-risk way for your business to not only help the environment but also reduce cost. It’s also one of the largest growing trends in business today. “Making a proper decision to go green in the workplace such as offices, not only improves the net profit of your business, but also reduces carbon dioxide emissions and your energy bill, this is the most effective thing you can do, and save our earth.”

" Green Design: Efficient design of data centers and workstations.

Designing energy-efficient environmentally sound components, computers, server, cooling equipment, and data centers.

" Green Manufacturing: Informed purchasing of component, peripherals

and equipments manufactured with the environment in mind. Manufacturing electronic components, computers, and other associated subsystems with minimal impact on the environment.

" Today, the main problem of the world is Global warming.

" The atmosphere is becoming hot & is causing many problems to living organisms.

" Computers also play a major role in polluting the world.

Why Go Green Computing

How Computing Harm Environment

Increase in power, cooling and space for data center • 2007-$4.5 billion of electricity • 2011-$7.4 billion of electricity (25 power plants) • 2011-Double CO2 output ( 62 million metric tons)

By electronic appliances. • Desktop requires 85 watts just to idle(Monitor off) • Left on 24 hrs/day-1,500 pounds of CO2 per year. • A tree absorbs between 3 and 15 pounds of CO2

each year.(up to 500 trees)

13


• According to reports from the German Federal Environment Office, devices consume around 17 billion (kWh) in a year in standby mode.

• The CO2 dissipated from ‘sleeping’ devices = 1/7th the CO2 emitted by an automobile.

• Manufacturers do not provide a proper shut-off button in devices.

• Windows Vista’s default shut down mode is a deep sleep mode that requires power.

14

• Hazardous materials inside computers. • These contain

– Cadmium (damage your kidneys) – Mercury (neurological damage) – Lead (disrupt brain neurotransmitters).

APPROACHES

Approaches to Green Computing

Product Longevity: • Gartner maintains that the PC

manufacturing process accounts for 70 % of the natural resources used in the life cycle of a PC.

• Another report from Gartner recommends to "Looking for product longevity, including upgradability and modularity."

17


Operating System Optimazion: • Windows 7 includes the OS that has improved the

system, so that more efficient use of time, the power management processor, and the brightness of the display panel.

• Linux OS utilizing less resources than other OS, and also have a better power management facility.

Terminal servers: • Terminals can be combined with thin clients, which use

up to 1/8 the amount of energy of a normal workstation.

Power management: • Prolong battery life. • Reduce cooling requirements. • Reduce noise. • Reduce operating costs for energy and cooling. • Lower power consumption. • The ACPI, an open industry standard • Under volting programs

19

Materials - IT Equipment Recycling: • If you can extend the working life of your IT

products, you reduce the environmental consequences of mining, manufacture, packaging, shipping and disposal.

• Many organizations, including some manufacturers themselves, are willing to take equipment back and recycle the components into new products.

Green computing

COMPUTER RECYCLING • Computer recycling is the recycling or

reuse of computers. • It includes: reuse old computer that

are still good or a donation to charity, or to be processed and reused into other products.

Consumer recycling : • Consumer recycling options include

donating computers directly to organizations in need, sending devices directly back to their original manufacturers, or getting components to a convenient recycler.

Virtualization: • It includes Server virtualization,

Consolidation, Storage consolidation & Desktop virtualization.

• Our typical computer used up to a 220-watt power supply; our thin client uses a 4.8-watt power supply.

22


Algorithmic efficiency: • The Efficiency of algorithms is used to

describe properties of an algorithm relating to how much resources it consumes.

• Algorithms are the base of any computing system or electronic device, each and every computer chip has a certain algorithm that allows it to complete its function.

• Even though these chips are small, they use a lot of power.

23

Power Supply Regular use of energy-efficient equipment and

continue to promote energy saving measures, reducing the impact of development that adds to greenhouse gas emissions and encourage the development of creative ideas for creating energy-efficient appliances and using more efficient power supplies.

Display: • LCD displays: use a CCF bulb • LED displays: use an array of LEDs • LCD monitors uses 3 times less when active,

and 10 times less energy when in sleep mode. • LCDs are up to 66% more energy efficient. • LCDs are also smaller in size and weight. • 21" CRT typically uses more than 120W.

25

Video Card • A fast VGA may be need the largest power consumer in

a computer • Energy efficient display option include: • No video Card – use share terminal, share thin client, or

desktop sharing software if display required • Use motherboard video output – typically low 3D

performance and low power • Reuse an older video card that uses low power. Many do

not require heatsink or fan • Select a VGA base on average wattage or performance

per watt.

$ CPU uses 120 Watts

$ CRT Monitor uses 150 Watts

$ Energy use comes from : o electrical current to run the CPU, memory, the fan and hdd

o Monitor CRTs consume more power than any other component

o printers

Methods to Implement Green Computing

12/15/13

11

• Turn off the computer when not in use, even if

just for an hour

• Turn off the monitor when not in use (as opposed

to running a screen saver)

• Use power saver mode

• Use LED Monitor, or LCDs instead of CRTs as

they are more power efficient.

• Use hardware/software with the Energy Star label

• Choose Intel & VIA Processors in comparison to

AMD Processors.

Reducing the energy consumption
