Green Computing

Neha Sahni

• Green computing is the practice of using

computing resources efficiently.

• Designing , manufacturing and disposing

Computer, servers with no impact on the

environment.

• To reduce the use of Hazardous materials,

maximize energy efficiency during product’s

lifetime.

What is Green Computing???

Why?????

Computer energy is often wasteful  Leaving the computer on when not in use

Printing is often wasteful How many of you print out your emails or meeting agendas 

Pollution   Due to manufacturing, packaging, disposal techniques

Toxicity Due to toxic chemicals involved in the manufacturing.

Need of green computing

Lead: used in soldering of printed circuit boards

lead can cause damage to the central and

peripheral nervous system , blood systems

and kidneys.  

Mercury: used in batteries, switches . Mercury spreads

out in water transforming into methylated

mercury that can cause chronic brain damage.

 

 Cadmium: used in resistors for chips and in

semiconductors . Cadmium is classified as toxic,

these compounds accumulate in the human body,

particularly the kidneys.

Manufacturing of PC’s

Bamboo : is becoming increasingly popular for making casings for computers and peripherals.

Recyclable plastics : computers are constructed from non-recyclable plastics ie recyclable polycarbonate resin.

  Eco-friendly flame retardant : there are flame retardant silicone

compounds available that are flame retardant and completely non-toxic. Inventory management : reducing the quantity of both hazardous

materials used in the process and the amount of excess raw materials. Volume reduction : removes hazardous portion of waste from non

hazardous portion.

Energy use of PCCPU uses 120 Watts

  CRT uses 150 Watts

8 hours of usage, 5 days a week = 562 KWatts

Energy use comes from Electrical current to run the

CPU, motherboard, memory

running the fan and spinning the disk. monitor

Turn off the computer when not in use, even if just

for an hour

Turn off the monitor when not in use

Use power saver mode

Use hardware/software with the Energy Star label

Don’t print unless necessary and you are ready

Use LCDs instead of CRTs as they are more power efficient

Reducing Energy Consumption

One of the first manifestations of the green computing movement was the launch of energy star program back in 1992.

Energy Star served as a kind of voluntary label awarded to computing products that succeeded in minimizing use of energy while maximizing efficiency.

Energy Star applied to products like computer monitors, television sets and temperature control devices like refrigerators, air conditioners, and similar items.

How to save energy while working on the internet ??

 

Sleep mode:

Sleep or standby mode conserves energy by cutting off power to your display, hard drives and peripherals.

  After a pre-set period of inactivity, your computer switches to a low power

state.

 

Hibernate mode : 

Saves energy and protects your work by copying system data to a reserved area on your hard drive and then completely turning off your computer.

  Reduces wear and tear on your components.

How to save energy while working on the computer??

Europe has outlawed using landfills for computer components Disposal of these devices constituted 20-50 million tons per year (about 5%

of the total waste of the planet) this waste is called e-waste Toxic chemicals in electronics products can reach into the land over time or

are released into the atmosphere, impacting nearby communities and the environment.

This releases heavy metals such as lead, cadmium and mercury into the air and ashes.

Disposal of components

Reuse: donate your computer components to people who may not have or have lesser quality computers.

Refurbish: rather than discarding your computer upgrade it. Change its some of the parts in order to make it new. 

Recycle: One of the major challenges is recycling the printed circuit boards from the electronic wastes. The circuit boards contain such precious metals as gold, silver, platinum, etc. and such base metals as copper, iron, aluminum.
