What is GREEN IT OR GREEN COMPUTING
• It describes the study and the using of computer resources in an efficient way.
• Green IT starts with manufacturers producing environmentally friendly products and encouraging IT departments to consider more friendly options like virtualization.
• power management and proper recycling habits.• maximize energy efficiency during the product's
lifetime.,

Why Green IT?•Save Money
•Save energy •Save in cooling
•Reduce carbon emissions
•Save space in server room and desktop

Approaches to green computing
• Virtualization
• Display
• Terminal Servers
• Power management

Virtualization• Computer virtualization refers to the abstraction of
computer resources• The concept originated with the IBM mainframe
operating systems of the 1960s, but was commercialized for x86-compatible computers only in the 1990s.
• With virtualization, a system administrator could combine several physical systems into virtual machines on one single, powerful system, thereby unplugging the original hardware and reducing power and cooling consumption.
• E.g.:- the process of running two or more logical computer systems on one set of physical hardware.

Do you know?
Companies can reap a 65%reduction in server count through virtualization.

Display
• Use LCD or LED display in place of CRT monitor
• Less amount of energy used in this practice
• More healthy enviroment.

Do you know?
PCs with a screensaver going can use well over 100Wof power, compared with only about 10Win sleep mode.

Terminal Servers• Terminal servers have also been used in green
computing methods.• When using terminal servers, users connect to a
central server; all of the computing is done at the server level but the end user experiences the operating system.
• These can be combined with thin clients, which use up to 1/8 the amount of energy of a normal workstation, resulting in a decrease of energy costs and consumption.
• Examples of terminal server software:-Terminal Services for Windows, the Aqua Connect Terminal Server for Mac

Power management• Implement power management system at
administrative level • allows an operating system to directly control
the power saving aspects of its underlying hardware.
• This allows a system to automatically turn off components such as monitors and hard drives after set periods of inactivity.
• Power managements benefits includes:- Saving energy
Saving time, reduce energy cost, life of hardware will increase etc.

Do you know?
Companies can save between $25 and $75 on power bills per PC per year by powering down machines when they're not in use.

CO2 emissions.
• Data center energy use in 2005 was 152billion kWh.
• 1.2% of USA energy use is consumed by data centers. Which corresponds with
0.8% of the world energy use.
