Introduction

• Refers to environmentally sustainable computing or IT.

• Study and practice of designing, manufacturing, using, and disposing of computers, servers, and associated subsystems—such as monitors, printers, storage devices, and networking and communications systems—efficiently and effectively with minimal or no impact on the environment.

• Application of the environmental Science to conserve the natural Environment and resources, and to curb the negative impacts of human involvement.

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

• Rs.35 per kWh• Rs.21 per hour

for a year– CO2 expulsion

• 23 lbs for 1 kWh• 1208 lbs for a year

EUP for Hardware

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

• $301.51per year• 7731.8 lbs of CO2

EUP for Applications

• A three server application• 354W consumption in idle• Rs.9000 annual cost

• Example – Simple write operation

EUP for Operating Systems

• Virtualization helps to reclaim about 20% of the peak energy consumption.• Disable unneeded services – Screen savers• Minimize disk activity – Fixed virtual disk size
