Growing public environmental awareness

Increasing impacts on environmental and human health

Corporate social responsibility
About Green Computing

Regulations And Industry Initiative


2. Industry
Roads To Green Computing
Green Use

Green Disposal

Green Design
Green Manufacturing

Algorithm Efficiency
Power Management
Power Supply
Material Recycling
VIA Technologies
Carbon Free Computing

Solar Computing

Lead-free And RoHS Computing

Energy Efficient Computing

Role Of IT Vendors


Energy Use of PCs
CPU uses 120 Watts
CRT uses 150 Watts
8 hours of usage, 5 days a week = 562 Kwatts
for a large institution, say a university of 40,000 students and faculty, the power bill for just computers can come to $2 million / year
Energy use comes from
electrical current to run the CPU, motherboard, memory
running the fan and spinning the disk(s)
monitor (CRTs consume more power than any other computer component)

Green Web Surfing
Greener Google

Being Green with Yahoo!

Greener FireFox Surfing

Other Green Surfing Efforts

Steps For Green Computing
Environmentally Sound Purchase Systems
Sustainable Green Computing Plan
Reduce Paper Consumption
Conserve Energy


Reduce Energy Usage
Conserving Resources
Reduces The Risk
Saving The Energy
Saving The Planet

Recent Implementations
Zonbu computer
Sunray thin client
The Asus Eee PC
Other implementations

Future Of Green Computing
The plan towards green IT should include new
electronic products and services with optimum
efficiency and all possible options towards
energy savings.
The greenest computer will not miraculously
fall from the sky one day, it’ll be the product of
years of improvements. The features of a green
computer of tomorrow would be like: efficiency,
manufacturing & materials, recyclability,
service model, self-powering, and other trends.
