This document discusses green computing and provides recommendations for implementing green computing strategies. It defines green computing as designing, using, and disposing of computers and associated hardware efficiently and effectively while minimizing environmental impact. It outlines approaches like virtualization and power management that can be used. The document recommends auditing data centers to remove unused equipment, virtualizing applications wherever possible, and considering data center consolidation. It also provides examples of companies that significantly reduced their server counts and saved over a million dollars through virtualization. Overall, the document promotes adopting green computing techniques to lower energy use and carbon emissions from information technology.

7. 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).

8. 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
-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
Energy 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

9. As 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

“processor”:
• 800x faster
• 1000x more memory
• 3000x less power

13. 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.

14. Virtualisation
• Virtualization: Duplicating hardware with
software
• Writing a program that does the same
exact thing as a piece of hardware
• Savings
Disposal
Power

15. Green Effects of Virtualization
VMware publishes numbers that say between 50-70%
can be saved from virtualization
The 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

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

18. 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

20.  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

21. 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.
