GREEN COMPUTING

GREEN COMPUTING

WHAT IS GREEN COMPUTING

the study and practice of designing, manufacturing, using, and disposing of computers, servers, and associated subsystems

such as monitors, printers, storage devices, and networking and communications systems

hardware implementations, algorithms, tools, services, and applications that can make computing systems more environmental respect

refers to supporting business critical computing needs with least possible amount of power or sustainable computing.

The goals of green computing are similar to green chemistry; reduce the defunct products and factory waste.

use of hazardous materials, maximize energy efficiency during the product's lifetime, and promote the recyclability or biodegradability of

defunct products and factory waste

Need for Green Computing

Climate changeEmissions are causing global

climate and environmental damage

Savings:Reductions in energy costs from

servers, cooling, and lighting

Reliability of power:energy supply is declining or flat

Computing:Computing Power Consumption

has Reached a Critical Point

Basis of Green Computing

Making.

replace petroleum-filled plastic with bioplastics—plant-based

Power-sucking displays can be replaced with green light displays made of OLEDs, or organic light-emitting diodes

polymers—require less oil and energy to produce than traditional plastics with a challenge to keep these bioplastic computers cool

Avoiding the discarding will not only control e-waste out of dumps but also save energy and materials needed for a whole new computer.

Future computers could knock 10 percent off their energy use just by replacing hard drives with solid-state, or flash, memory

Landfills can be controlled by making best use of the device by upgrading and repairing

Use of toxic materials like lead can be replaced by silver and copper

recycling of computers (which is expensive and time consuming at

present) more effective by recycling computer parts separately with a

option of reuse or resale
