What is Green Computing?

Increasing impacts on environmental and human health

Growing public environmental awareness

Corporate social responsibility

Green Computing – Why?

Approaches to Green Computing

Virtualisation Power Management Power supply DisplayIT Equipment RecyclingRemote Conferencing & Telecommuting StrategiesAlgorithmic efficiency

How to Implement?Audit your data centre and remove unused equipment and software.

Virtualise applications, storage and

servers in the data centre wherever

appropriate.

Consider consolidating data centres.

Use of toxic materials like lead can

be replaced by copper.

• Power-sucking displays can be

replaced with green light displays

made of OLEDs, or organic light-

emitting diodes.

• Buy and use a low power desktop or a

laptop computer (40-90 watts) rather a

higher power desktop (e.g. 300 watts).

CPU uses 120 WattsCRT 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 / yearEnergy use comes from -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 of PCs

Power ConsumptionAs circuit speed increases, power consumption grows

Designing low power circuits has been the most important issue

Mobile applications demand long battery life Low power consumption is listed as the second greatest challenge for the industry

A Perfect “Green Computing” Example

A super low-power “processor”:

• 800x faster• 1000x more memory• 3000x less power

Contd….Modern Processor made

by hundreds of PH.D. researchers (The MOS transistor was built from

Silicon, the pre-dominant atom in rock and sand, after

processed in a high temperature.)

Human Brain( containing 100 billion neurons, each linked to

as many as 10,000 other neurons.)

Speed 2.0 GHz Equivalent to 1,700 GHz processor

GREEN IT FOR BUSINESS:

Rising energy prices, together with government-

imposed levies on carbon production, are

increasingly impacting on the cost of doing

business, making many current business

practices economically unsustainable. It is

becoming progressively more important for all

businesses to act in an environmentally

responsible manner, both to fulfill their legal and

moral obligations, but also to enhance the brand

and to improve corporate image.

Virtualisation

• Virtualization: Duplicating hardware with software

• Writing a program that does the same exact thing as a piece of hardware

• Savings Disposal Power

Green Effects of VirtualizationVMware publishes numbers that say between 50-70% can be saved from virtualizationThe Gartner group says that the energy savings of jobs running VMware alone will power all of New England! (they give no actual rates or metrics but this is an interesting claim)

Who is doing this?The USDA used virtualization to reduce/consolidate 255 servers into 22!4 Years ago, Los Alamos National Laboratories undertook a virtualization project that decommissioned 100 servers, resulting in the use of only 13. This has resulted in a savings of almost $1.5 Million dollars

INDUSTRIAL IMPLEMENTATIONS OF GREEN COMPUTING:

Blackle Fit-PC

Zonbu computer The Asus EeePC

The plan towards green IT should include new electronic products and services with optimum efficiency and all possible options towards energy savings.

FUTURE OF GREEN COMPUTING:

Advantages:

-Energy saving&Environmentally Friend

-Save more money per year

-Green computing techniques will actually translate into a much lower carbon dioxide emission

Disadvantages:

-High start up cost

-Not readily available-

- Still in experimental stages

FIVE TIPS FOR GREEN COMPUTING

Final Recommendations

Pick all the low hanging fruit Small changes make big

difference

Conduct energy assessment Set baseline…& measure,

measure, measure

Must use BLACKLE as search engine

Conclusion

The greenest computer will not miraculously fall from the sky one day, it’ll be the product of years of improvements. The features of a green computer of tomorrow would be like: efficiency, manufacturing & materials, recyclability, service model, self-powering, and other trends.
