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
