This document discusses green computing and how to make computing more environmentally friendly. It defines green computing as using computers in an environmentally sustainable way by reducing hazardous materials and maximizing energy efficiency. Some key ways to achieve green computing mentioned are using power management and energy efficient hardware, recycling electronics properly, and utilizing more sustainable power sources like solar energy. The document provides tips for green computing practices like turning devices off when not in use, using energy efficient monitors, and printing only when necessary.

2. • Also called as Green IT.
• It is an environmental friendly IT where the
main objective is to reduce the hazardous
materials and maximize the energy efficiency .
• Reduce the power consumption and thus
reduce the global warming.

3. • Computer consumes a lot of energy.
• Printing often unnecessary stuff is waste.
• Reduce pollution.
• Toxicity.

4. • It originated in 1992 at the U.S
Environmental Protection Agency that
launched Energy Star program.
• Shortly after that the term “Green
Computing “ was coined.
• Shortly after that the Swedish also launched
the TCO Certification.

5. • CPU uses 120 Watts.
• CRT uses 150 Watts.
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)
 printers

6. The following are the pathways to green
computing:
• Green Use
• Green Disposal
• Green Design
• Green Manufacturing

7. • Product Longevity
• Software & deployment
optimization
• Power management
Materials
• Recycling

8. • Carbon Free
Computing
• Solar Computing
• RoHS Computing
• Virtualization

10. • Turn off the computer when not in
use, even if just for an hour.
• Turn off the monitor when not in use (as
opposed to running a screen saver).
• Use power saver mode.

11. • Use LCDs instead of CRTs as they are more
power efficient.
• Use hardware/software with the Energy Star
label.
• Don’t print unless required.
• Choose Intel & VIA Processors in comparison
to AMD Processors.

12. • Improve the savings.
• Eco-friendly and environment friendly.
