This document discusses green IT and sustainability in technology. It begins by defining green IT as the practice of designing, using, and disposing of computers and associated systems efficiently and with minimal environmental impact. It notes that green IT aims to address issues like rising energy costs, global warming, and electronic waste. Examples of green IT solutions provided include using more energy efficient hardware like laptops and LCD monitors, enabling power saving settings, virtualization, recycling electronics, and reducing overall energy and materials usage. The document emphasizes that green IT can provide cost savings and environmental benefits if adopted widely.

3. WHAT IS GREEN IT?
 "The study and practice of designing,manufacturing, using, and disposing of computers,
servers, and associated subsystems efficiently and effectively with minimal or no impact

4. WHERE IT STARTED?
ENERGY STAR:
 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.

5. WHY CAUSING THIS ATTENTION?
 Rising energy costs over the past five years
 Increased publicity regarding global
warming and “energy citizenship”
 Increased legislation surrounding energy
efficiency, toxic materials, and greenhouse
gases (GHG) in the US,European Union and
China

6. "Moore's law“:
Gordon Moore, co-
founder Intel,
predicted that
computer processing
power roughly
doubles every two
years.
ICT accounts for
2% of of global
CO2 Emission
‘ state-of-the-art’
machines
threatened by
obsolescence.
Approx 50 million
tons of e-trash
generated a year
worldwide, according
to the UN
Environment
Programme.

7. REAL REPORTED ISSUES:
Lack of awareness and attention can result in
excess energy consumption and harmful disposal
practices for IT equipment
Selection Use of laptops, LCD monitors can
significantly reduce electricity consumption and
costs
Simple asset usage practices, such as turning off
PCs at nights and on weekends and using power
saving settings during the day, can reduce energy

8. ENERGY USE OF PC’S:
 CPU uses 120 Watts
 CRT uses 150 Watts
 8 hours of usage, 5 days a week = 562 Kwatts
 for a large institution, say a university of 40,000 students and faculty,
the power bill for just computers can come to $2 million / year
 Energy use comes from electrical current to run the CPU,
motherboard,memory components.
 running the fan and spinning the disk(s),monitor (CRTs consume
more power than any other computer component)

9. PROBLEMS ON DISPOSAL:
 Consider that the average computer lifespan is about 2 years (cell
phones < 2 years) 10 years ago, the lifespan of a computer was 5
years between 1997 and 2004,
 it is estimated that 315 million computers became obsolete (and
were discarded, donated, or recycled)
 183 million computers were sold in 2004 (674 million cell
phones!)
 New users in China (178 million by 2010) and India (80 million by
2010) will require the creation of new computers
 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

10. HOW TO SAVE ENERGY WHILE
BROWSING?
 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
 Set Blackle as your homepage.

11. HOW TO SAVE ENERGY ON COMPUTER?
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

12. EXAMPLES OF GREEN IT:
 Renewable energy technologies
 Energy efficient hardware
 Cloud Computing
 Green Networking (virtualization)
 Green Data Centers
 Recycling

13. Desktop Virtualization and Thin Client:
Desktop
virtualization
Reduce Energy
Consumption
Decrease cost of
maintenance and
management

14. VARIOUS SOLUTIONS:
LANDFILLS
3 R’S
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.

15. BENEFITS OF GREEN IT:

16. CONCLUSION THE GREENEST COMPUTER WILL NOT
MIRACULOUSLY FALL FROM THE SKY
ONE DAY, IT’LL BE THE PRODUCT OF
YEARS OF IMPROVEMENTS. THE
FEATURES OF A GREEN COMPUTER OF
TOMORROW WOULD BE LIKE:
 EFFICIENCY,
 MANUFACTURING & MATERIALS,
RECYCLABILITY,
 SERVICE MODEL, SELF-POWERING,
AND OTHER TRENDS
