What is Green Computing?

Green Computing:

"The Minimum energy gives maximum reliability and timing."

Green Computing involves reducing the electricity consumed and environmental waste generated when using a computer.

How computer energy often wasteful?

• Leaving the computer on when not in use,
• CPU and Fan consumes power,
• Screen Savers consumes power,
• CPU uses 120 watts.
• Monitors use 150 watts.
• 8 hours of usage, 5 days a week=562 KW.

For a large institute, like university of 40,000 students and faculty,the power bill for just computers can come to $2 millions/year.

Reduction of energy consumption:

1. We can reduce energy consumption for a computer by turning off the computer when not in use, even if just for an hour.
2. Turning off Monitors when not in use.
3. Screen Savers uses as much electricity as any normal processing, and screen savers are nit necessary on a flat panel display.
4. Use hardware/software with Energy star Label.
5. Don't print unless necessary and you are ready.
6. Use LCDs instead of CRTs, as they are more power efficient.
