2. Negawatt
Negawatt power is a theoretical unit of power representing
an amount of energy (measured in Watts) saved. Energy is
saved by either increased efficiency or reduced energy
consumption; the conserved energy is a "negawatt".
The concept of a negawatt is simply a measure of power that
is not used. Negawatts are a form of encouragement to
motivate consumers to conserve energy.

3. ICT Energy consumption Facts
ICT is responsible for 5 %–
10% total electricity
consumption
In US Only 10-15 more In administrative
power plants needed by industries (Governments,
2011 to keep up with Banks etc.) ICT can
data center power account for up to 75% of
consumption all energy consumption
Most of the IT 3 -5 % of total world
Departments are not electricity consumption is
responsible for electricity based on software driven
bill devices
Datacenters are one of the fastest
growing consumers of energy.

4. ICT GHG emission facts

7. How to reduce infrastructure cost
• Analyze actual workload
• Eliminate unnecessary components
• Operate Servers at higher temperature
• Use higher efficiency power and cooling
• Chiller-less design
• Optimize for performance/watt/$
• Drive server consolidation with Reduce
virtualization Cost
• Leverage advanced power management
