What is Green Computing?
12/3/2012 Impact Lab 3
Is it about a different hardware?
Just a buzz word?
Renewable energy?
How green is green computing?
Green Computing
Green Computing Initiative defines it as:
“Eco‐Friendly Green Computing is the study and practice of the design, development, implementation, utilization and disposal of sustainable information technology infrastructure efficiently and effectively with low or zero impact on the environment whilst reducing operating costs.”

Data center technologies• Mega data centers
– Colossal computer facilities packed with tens of thousands of servers to power cloud computing.
• Data center in container– Modularized data centers

• Cloud computing is availability of access to computing facility, storage, applications over the internet with use of no specific hardware at the user end.
Container
Advantages• Scalability
– Deployment time is faster• Flexibility
– Modular data center will be used when required, shipped to destinations when required
• Security– Limited people access
container infrastructure• Technology
– Modular contained can be updated with latest equipment
Disadvantages• Requires more space.• Cost increase due to
individual infrastructure.

Caveats –Natural gas
• Is natural gas green?– Researchers at Cornell University say “When burned to generate electricity, natural gas emits roughly half as much carbon dioxide per megawatt‐hour as coal.
– But over its life cycle, natural gas could result in far more greenhouse‐gas emissions, whether through intentional venting, equipment leaks, or cracking.”

• Use equipment that automatically goes to sleep – (Energy Star)
• Turn off the peripherals• Use ink jet printers as they use 80‐90% less energy than laser jet.
• Use flat panel monitors replacing the CRTs.
• Use renewable energy• … more…

Are these savings really enough to save our future environment?
Jevons Paradox: When Doing More with Less Isn’t Enough
If our machines use less energy, will we just use them more?http://www.newyorker.com/reporting/2010/12/20/101220fa_fact_owen#ixzz1ZpkWtzCp

Sustainability solutions
In a first‐of‐a‐kind trial, the planned Aquasar system will use water to cool thesupercomputer’s processor.Through a network that emulates the human vascular system, and highly efficient chip‐levelcoolers, 60°C water will be used to cool the processor’s chips and transport excess heat away.This will be directed towards the heating system of ETH Zurich where the energy can bereused (see diagram). The system could potentially save up to 30 tons of CO2 per yearcompared with a similar system using current cooling technologies

Summary
• Data center are becoming expensive and affecting the environment, hence Green Computing initiatives are coming into picture.
• Green Concepts provides solutions to sustainable computing saving more resources and money.
