Introduction

• Green Use
• Green Disposal
• Green Design
• Green Manufacturing

Profiling Energy Usage For Efficient Consumption

• What is Energy Usage Profile (EUP)?
• A simple Experiment
• A Simple Fluorescent bulb (60W)
• 1 Hour consumption 0.06 kWh
• Cost
• 0.0897 per kWh
• 0.0054 per hour
• 47.15 for a year
• CO2 expulsion
• 23 lbs for 1 kWh
• 1208 lbs for a year

4
EUP for Hardware

• Server consumption
• 383.75W in Idle
• 454.39W in Stress

• 301.54 per year
• 7731.8 lbs of CO2

5
EUP for Applications

• A three server application
• 354W consumption in idle
• 226.67 annual cost
• Example Simple
• write operation

6
EUP for Operating Systems

• Virtualization helps to reclaim about 20
• of the peak energy consumption
• Optimization is the key
• Disable unneeded services Screen savers
• Minimize disk activity Fixed virtual disk size

7
Approaches to GREEN COMPUTING

• Algorithmic Efficiency
• Power Management
• Video Card
• Display
• Materials Recycling
• Telecommuting

To summarize

• Green computing is a novel and an innovative
  trend in the world of computing which has minimum
  or no impact on the environment.
• Green computing has introduced a range of
  equipments and technologies which help in
  limiting the impact on the environment.
• Use of EUPs help in different aspects of the
  computing world help in recognizing the areas
  for improvement.
