IntroductionCore objectives for a Green IT Strategy could include:

Minimizing energy consumption Purchasing green energy and using green

suppliersReducing the paper and other consumables

usedMinimizing equipment disposal requirements

Strategies of Green Computing:

4

WEEEWaste Electrical and Electronic Equipment (WEEE)

Includes computers, consumer electronics, fridges etc which have been disposed of by their original users

Contains both valuable materials as well as hazardous materials which require special handling and recycling methods

5

How to reduce E-Waste?Acrylonitrile Butadiene Styrene (ABS)

It is a common thermoplastic. Its melting point is approximately 105 °C (221 °F)

The plastics used in computers and servers are ABS plastics

disadvantage :ABS is that it is not ROHS (Restriction of Hazardous Substances) compliant and non-eco friendly

6

Cereplast (Cereal + plastic)• It uses corn, tapioca, potatoes and algae, including polylactic acid polymer (PLA), to produce

compostable plastic resins designed to serve as an alternative to petroleum-based plastics• It is 100% renewable plastic• Cereplast products can be discarded with food waste – no separation required

E-PaperCharacteristics of e-paper :

Low power consumptionConvenient for use on curved surfacesNo electricity required for continuous displayConserves energy by consuming only one 1/100 to 10/10000 the energy of conventional display technologies High-level display performance3 displaying layers - red, green and blue(RGB)

Bloom BoxCharacteristics of Bloom Box:

MAKE CLEAN & RELIABLE ENERGYAFFORDABLEreduced operating costs NO GREENHOUSE GAS EMISSIONSEach fuel cell, which consists of a metal alloy plate sandwiched between two ceramic layers, generates 25 watts of power

Green Clouds

Save energy and money for your business.

If you have a cloud computing solution set up, you can draw on the additional computing power and resources you need just when you need them.

You won't be paying the energy costs for running servers and the associated costs the rest of the time.

a reserve that you can allocate without the need to pay for the resource sitting idle in one fixed location.

cloud computing may allow for you to make your IT infrastructure far more green than it is currently.

Solar ComputingComputers working with the the help of Solar Technology are called Solar ComputingThey are charged by the sun, not technology.The most basic technology used in solar power is the solar electric panel. These panels use photons in order to generate electricity. These photovoltaic (PV) panels can be free standing rigid sheets used to harness the sun's energy. Cutting costs is the main reason people use solar power in the industriesThe use of solar power is thought to pay for the installation cost in about 12 years.

Energy StarENERGY STAR is the trusted, government-backed symbol for energy efficiency helping us all save money and protect the environment through energy-efficient products and practicesIt was first created as a United States government

The ENERGY STAR label was established to

Reduce greenhouse gas emissions and other pollutants caused by the inefficient use of energy

Make it easy for consumers to identify and purchase energy-efficient products that offer savings on energy bills

Devices carrying the Energy Star logo, such as computer products and peripherals,, generally use 20%–30% less energy than required by federal standards

Conclusion•

“Modern technology Owes ecology an apology.”
