Green IT
Shreyal Deshmukh
In our routine
life we consume large quantity of energy. Like in household appliances, lighting
purpose, in industries, and to fulfil all artificial needs we need energy.
As care is not
taken sufficiently, wastage of energy is increasing everyday. And such
conditions are really hazardous if we take future in to account. To avoid such
condition some new technologies & methods are developed.
Despite of all
our daily needs, the IT structures are developing rapidly. The use of power in
a single IT company is much more than a thousands of households.
But, if we
consider modern IT system, it is very complicated over this issue. So to
simplify the need of power Green IT concept is developed which saves the
wastage power.
Some technologies & methods followed in Green IT are
enlisted below-
a) In Data Centres, server
is utilized under utilization condition. Therefore, it helps to save power.Saving
in done in various modes such as ‘Cold Standby’ or ‘Hot Standby’. This saved
power is automatically used when we need supply of power. Such utilization
server gives more workable capacity after storage of the power. This energy is
used in different kind of necessities.
Energy that is
to be wasted is securely stored & used in a needble condition.
b) Another technology to
save energy is named as Green computing. Green computing is the study &
practice of using computing resources efficiently. In this energy is saved
during products lifetime.
In green
computing ‘Virtualization’ is also a one technique in which number of computer
systems are run on one set of physical hardware. In which total systems is arranged
in one virtual machine that is supply to other computer. It reduces consumption
of power.
Speed step is
very important investigation in this condition. It is the program which
suggests user to adjust the power supply on CPU’s . Also Some C P U are work automatically
under volt condition.
To contribute this green mission globally top ten
methods are as follows:
1) Laptop power
scheme
2) Home / office
desk scheme
3) Presentation
scheme
4) Always on
5) Minimal power
Management
6) Max battery
7) Standby mode
8) Hibernation
mode
9) Stop
unnecessary Application
10) Miscellaneous
strategies
Trendsetters:
Some of the
trendsetting examples who followed concept of green IT very seriously are:
1) Vista
power conservation
2) In 2006, the city university of New-York
installed a program on it computers that would automatically turn off the
computers if they were idling in the dark. In come year savings were
substantial close to $320,000.
3) Data centres
of IBM and DELL are also making tremendous changes in their traditional systems
to save energy consumption.
Origins:-
In 1992, the U.S
environmental protection agency launched energy star, a voluntary labelling
program. According to which consumer can buy
the green products and services
Industry:-
1) Climate
savers computing Initiative (CSCI) is an effort to reduce the electric power
consumption of PC, in active & inactive stales.
2) Green
computing impact organization (GCIO)
3) Green
electronics council
4) The Green
Grid
No Matter that you are
a home user or some corporate, making changes in your traditional computers
will helps you to save our planet earth as well as helps you economically.

Power Saving Web Search: Blackle
Sachin Rasal
Internet is the solitary medium of communication in the IT sector and
it plays a foremost role for growth of any business. No matter you are
a hardcore user or a novice, you have to depend on internet search
engines. Search engines make your surfing faster as well as enjoyable.
Google, Live Search, Yahoo Search are some of them leading the search
engine market.
So how the Green IT and search engines are related any way?
Well, when you search through web, the search bots passes through
millions of webpages to get the relative results. Again to show the
final results in the form of text, images, and graphics numerous amount
of energy is gets consumed. Only few of the results are useful and rest
is wasted.
Search engine giant Google noticed this fact and took the initiative to
go green in this business. They have developed ‘Backle’
– The energy saving search engine.
The whole search engine and the search engine results come in the black
color (So the name is Backle). Because of using black color they save
much of energy as every pixel on users monitor is in the same color
which consumes the least in all 256 colored web pallet.
“Intelligent, isn’t it?”
What are you thinking then? From now on whenever you wanted to search , use Backle search
engine and save energy. Remember your contribution matters.
(Blackle also displays how much energy they have saved up to date on their webpage)

Top 10 ways to save power when using your computer
Joji Joy
Information technology consumes large amount energy. Using Laptops,
computers, printers and many other supporting gadgets consumes energy
in considerable amount. And use of these technologies is substantially
increasing as well.
So if we can figure out where actually we are consuming energy causes
and their consequences then we can save big part of environment through
IT industries as well as personal computing. After the experiment in US
to idling the computers when not in use then they have saved thousands
of dollars which indicates that many things can be possible and very
easily implemented in our IT sector
Can’t we do some thing to protect our environment as described
above? Can’t we save some amount of power? Think that we are
having a vacation. What to do with that? Turn your computer off!
Remember to turn off your monitor, speakers, printer, scanner or any
other hardware that does not power down when you turn off the computer.
It’s a good idea to use the power management system on your
computer.
Here are some tips on how to use the options on your computer. These
should be followed step by step to achieve the power saving results.
1. Laptop Power Scheme
For laptops, there are many power schemes to decrease power consumption. One is the Portable/Laptop power scheme.
To use this setting,
Go to
Start->Control Panel->Performance and Maintenance-> Power Options->Advanced Tab.
Use this setting, when you don’t want to change the settings
throughout the day. This scheme works well in most situations. This
setting turns off monitor, hard disks and system goes into standby
before it goes into hibernation after 3 hours of idle time.
2. Home/Office Desk Scheme
This scheme also turns off monitor, but does not turn off hard disks or
take the system to standby or hibernation state unless its battery
powered. So it uses more power than Option #1. Use this scheme when you
are at the desk a lot and have to quickly restore your work. This is
also the best option when connected to continuous AC power.
3. Presentation Scheme
In this scheme, everything stays ON unless it’s powered by a
battery. The hard disks are turned off after 5 minutes of idle time;
system goes on standby after 15 minutes and into hibernation in two
hours. This scheme is useful when giving a presentation or watching a
DVD.
4. Always On
This scheme suggests that the computer runs all the time. The monitor
turns off after 15 or 20 minutes, and hard disks shut down if the
computer is battery powered. This may be used when the computer needs
to respond immediately to requests over a network.
5. Minimal Power Management
For a system that is not on battery power, the only change is that the
monitor is turned off after 15 minutes. If the system is running on
battery power, monitor turns off after 5 minutes. This scheme may be
used if you have a fully charged battery and is using it to view
information except for a few idle intervals.
6. Max Battery
This may be used when we are doing tasks that do not need a lot of CPU
processing and use this when you would like to conserve battery power.
When this scheme is used on AC power, the monitor is turned off after
15 minutes, (hard disks are not turned off), and system goes into
standby after 20 minutes and into hibernation state after 45 minutes.
On battery power, monitor is turned off after 1 minute, hard disk is
turned off after 3 minutes, and system goes into standby mode after 2
minutes and into hibernation state after one hour.
7. Standby Mode
We can also take the computer directly to standby mode.
Go to
Start-> Control Panel->Performance and Maintenance->Power
Options->Properties->Advanced Tab. Under power buttons, click
Standby.
In this mode, the monitor and hard disk are turned off, all open
programs and files are stored in RAM. Information stored in RAM is
cleared when the computer turns OFF. Remember to save your work and
close all applications you don’t need before moving your system
to standby mode.
This is useful if you are using your computer intermittently during the
day. Standby mode allows quick access to open applications and also
maximizes the life of your battery. In this mode, the desktop does not
change its appearance when you return to it.
8. Hibernation Mode
To go into hibernation mode manually, choose
Start->Control Panel->Performance and Maintenance->Power Options Properties->Hibernate Tab->Enable Hibernation.
This mode saves all open work into the hard disk and then shuts itself
down. This saves a lot of power even though the computer takes a little
while longer to return to the original screen. This mode is good when
you know that you may not be back for a while.
9. Stop unnecessary Applications
There are several other changes you can make in your environment to
save energy and consume less power. Turn off all applications that are
not required. Programs such as IM, Skype, Music Online etc have
programs running in the background. Reduce the number of services that
run on the machine to conserve CPU power. Look for the icons in the
task bar which indicate processes that are running to detect a CD or
DVD or some other device. Reduce brightness of monitor may save some
energy especially if it’s running on battery power. Devices such
as a wireless card expends a lot of power even when its not being
actively used.
10. Misc. Strategies (Same as Enlisted in Green IT Article)
There are some more simple things we can do to minimize power wastage:
1. Do not use screen savers that have intensive graphics
2. Use LCD monitors rather than CRT
3. Consider a video card that does not consume a lot of energy
4. Buy the PCs based on low power consumption chips
5. Use an efficient power supply
6. Use ceiling fans and close the blinds in the computer room
7. Install energy efficient windows in the computer room
Computers will be more developed for sure to let them decide where they
should go idle and save power. IT industries have proved in past they
can make computer think more and more with their new software and
hardware launches. We have to wait till that day but still then these
quick tips can be very helpful economically as well.
