2. • The concept of green IT emerged in 1992
when the U.S. Environmental Protection
Agency launched Energy Star, a voluntary
labeling program identifies products that offer
superior energy efficiency.
• Organizations and consumers that use
Energy Star products save money and reduce
3. ENERGY
STAR
ENERGY STAR is the government-backed symbol
for energy efficiency.
It was introduced as a volunteer labeling program to
identify and promote energy-efficient products.
ENERGY STAR products, which can be identified by
the label pictured above, use less energy and help
you save money on your electric bill.
4. Its goal is to help consumers, businesses, and
industry save money and protect the environment
through the adoption of energy-efficient products
and practices.
The ENERGY STAR label identifies top-performing,
cost-effective products, homes, and buildings.

7. Green Personal Computer
• A green PC is also known as a
green computer.
• A green personal computer (green
PC) is a computer designed to
save energy.
• A green PC is built from
environmental friendly materials
and features low power
consumption and computer power
management (CPM) capabilities.
Green PCs usually generate less
heat than their predecessors.
8. • Deployment of efficient computing systems and green PCs has become a
major focus of many organizations.
• Companies and businesses are keen to reduce their energy consumption and
carbon footprint.
• This has resulted in increased public awareness and ongoing efforts to reduce
energy use.
• Green PCs support sleep modes in which the PC powers down all unnecessary
components when it is inactive because it is wasting the electricity.
• As it generate heat and require additional cooling, which add to the total
power consumption and cost.

9. Reduce PC energy consumption by adopting several
measures:
• Reduce computer monitor’s brightness: Most monitors have a built-in sensor
that adjusts the screen’s brightness according to the amount of light in the room.
We can also manually adjust our PC’s brightness to further reduce its power
consumption.
• Unplug computer when it’s not in use: Many people leave their computers on
all day, even when they’re not using them, to save time powering up. However,
this practice wastes a lot of energy. If we are not going to use the computer for a
while, it’s best to shut it down and unplug it. That’s because a plugged-in
computer (even when it’s switched off) still consumes standby power.
• Option for laptop instead of desktop computer: Use a laptop instead of a
desktop since laptops are designed to be more energy-efficient than desktops.
• Keep laptop plugged in only when it is charging: We leave the laptops
plugged in for hours, while they’re charging. The bad news is that overcharging
causes the battery to deteriorate over time. When left plugged in, the charger
still consumes power, even if it’s not connected to the computer. To save energy,
unplug the laptop charger once we are done charging.
10. • Detach external devices from your PC when you’re not using them:
Any external devices (e.g., printer, scanner, or webcam) connected to your PC
continues to draw power even when they’re not in use. So when you’re not
using them, make sure to disconnect these external devices from your PC.
• Use a smart strip, especially for computers you cannot turn off:
A smart strip automatically shuts down appliances when they go into standby
mode. By connecting your computer and external devices to a smart strip,
you won’t have to unplug your equipment when they’re not in use.
• Pick an Energy Star-Certified PC: When buying a new PC, look for an
Energy Star-certified model. Products that have the Energy Star symbol are
guaranteed to deliver both quality performance and energy savings. The
number of stars a product has indicates how energy-efficient it is.

12. Building and certifying a green data centre or other facility can be expensive upfront but
long-term cost savings can be realized on operations and maintenance.
Another advantage is the fact that green facilities offer employees a healthy,
comfortable work environment.
Green facilities also enhance relations with local communities
The following are examples of some of the technologies and strategies used in green
a) Minimized Building Footprints.
b) Low-emission Building Materials, Carpets And Paints.
c) Sustainable Landscaping .
d) Waste Recycling.
e) Catalytic Converters On Backup Generators.
f) Alternative Energy, Such As Photovoltaic Technology, Heat Pumps And Evaporative Cooling
Technology And Hybrid Or Electric Vehicles.
