• 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???
![Page 3: Green computing](https://reader035.fdocuments.in/reader035/viewer/2022062706/557d9eddd8b42a642d8b484e/html5/thumbnails/3.jpg)
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.

Blackle is a website powered by Google Custom Search and created by Heap Media, which aims to save energy by displaying a black background and using grayish-white font color for search results.
Blackle saves energy because the screen is predominantly black

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.

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.
