Green Computing

What is Green Computing

• •Simply Green Computing is the process of using computers & their resources in an eco-friendly manner.
• •In broader terms ,it is defined as the study of designing,manufacturing/engineering,using & disposing of computing devices in a way that reduces their environmental impact.

Goals in Green Computing

• •Minimizing Energy Consumption
• •Emphasize on recycling
• •Reduction of hazardous materials
• •Purchasing green energy
• •Avoiding toxicity

Roads to green computing

• •Green Use: Minimize electricity consumption
• •Green disposal: Re-making an existing computer or recycling
• •Green design: Designing energy efficient computers & digital devices.
• •Green manufacturing: Minimizing waste during the manufacturing of computers & other devices.

Tips to make your computing usage more green

• •Use LCD monitors than CRT monitors.
• •Set Blackle as your home page.
• •Put laptops in sleep or hibernate mode when not in use.
• •Buy Energy Star labeled monitors,desktops,laptops & printers.

What is Energy Star?


The term green computing was probably coined shortly after the Energy Star program was began way back in 1992.
This program is designed to promote & recognize energy efficiency in monitors, climate control equipment and other technologies.

Approaches to Green Computing

1. Vitualization:

Process of running two or more logical computer systems on one set of physical hardware.

2. Power Management:

A CPI allows an operating system to directly control the power saving aspects of it is underlying hardware.

3. Power Supply:
Climate savers computing initiative promotes energy saving and reduction of green house gas emissions by encouraging development and use of more efficient power supply.



4. Storage:

5. Video Card:

6. Display:

7. Materials Recycling

Advantages and Disadvantages

Roads to green computing

So far, consumers have not take care on ecological impact when buying computers, they have cared only about speed & price.
Therefore my aim through this article is to make your attention on Green Computing & start to move with green products to save our future.

It’s not easy not being green.

So let’s go GREEN !!!!!!!
