GREEN COMPUTING
Introduction
Green computing is the study and practice of using computing resources efficiently in an eco friendly manner”
Goals of Green IT
A shocking fact:
Every Google search produces 0.7 g of co2
91 million searches/day
18.2 tonnes co2/day
About 7000 tonnes/year
HISTORY
In 1992 U.S Environmental Protection Agency created Energy Star program
Energy Star
Program designed to reduce energy consumption and greenhouse gases
Promote energy efficient products
Green IT Approaches
Virtualization
Power management
Power supply
Video card
Displays
IT Equipment recycling
Product longevity
Operating system support
Virtualization
Process of running two or more logical computers on one set of physical hardware
Server virtualization
Thin client
Typical PC-220W
Thin Client-4.8W
Power Management
Keep computers and PCs turned off ,when not in use.
Disable screen saver.
Use LCDs instead of CRTs as they are more power efficient
Enforce standardized energy settings before distributing to end users
POWER CONSUMPTION
Power supply
Generally PCs are 70-75% efficient
Remaining are lost in the form of heat
«80 PLUS» certifies PSUs(Power supply Units) that are at least 80% efficient
Energy Star 4.0-certified desktops must be at least 80% efficient
Video Card
Fast GPU is one of the larger power consumer in PC
Display options for Green IT are
1.No video card
Shared terminal
Thin client
2.Use Motherboard video output
Low 3D performance
Low power
Displays
Use LCD instead of CRTs
Advantages of LCDs
Up to 66% energy efficient than CRTs
Produces less heat
Easier to eyes
IT Equipment recycling
Recycling computing equipments can keep harmful materials such as lead, mercury, and cadmium out of landfills.
www.eiae.org - informations about recycling
Lead : Common in CRTs and some batteries
Mercury : In fluorescent tubes
Cadmium : In some rechargeable batteries
LEAD
Common in CRTs and some batteries
The problem:
cause damage to the central and peripheral nervous systems, blood system, kidneys, endocrine system and cause negative effects on child brain development
lead accumulates in the environment and has toxic effects on plants, animals and microorganisms
MERCURY
• is used in
– batteries, switches, printed circuit boards
• The problem
– spreads out in water transforming into methylated mercury which easily accumulates in living organisms
– it enters the food chain through fish that swim in polluted waters
– methylated mercury can cause chronic brain damage
• Product Longevity
– Equipment should have a prolong lifetime
– Upgrade the computer instead of manufacturing a new one
