Harnessing Green IT: Principles and Practices BY: Patrick N. Zwane Advisor: Dr. Kai-Wei Kea Date:18/03/2016 Green Computing

Online Overview of Green Concept Green IT IT’s Environmental Impact A Holistic Approach to Green IT Benefits of greening IT Conclusion Green Computing

Overview of Green Concept Environment in Present Days: Air pollution, Water pollution, Land pollution Green Computing

Overview of Green Concept Cont.’s Global warming : Ice cap at the North Pole continues to shrink! Green Computing

Overview of Green Concept Cont.’s Electronic wastes : In the U.S. alone, 500 million obsolete computers, and 130 million cell phones are thrown out every year. Green Computing

Why Green, Not Yellow or Red? G enerate less waste r ecycle everything that cannot be reused e ducate the community on eco-friendly options e valuate the environmental impact of actions n ourish discussions and activities that integrate environmental education into existing curriculum Green Computing

Green IT Green IT refers to environmentally sound IT the study and practice of designing, manufacturing, disposing of computers, and associated subsystems efficiently and effectively with minimal or no impact on the environment Green Computing

Green IT Cont.’s Green IT spans a number of focus areas and activities, including: design for environmental sustainability energy-efficient computing power management data center design, layout, and location server virtualization Green Computing

Green IT Cont.’s responsible disposal and recycling regulatory compliance green metrics, assessment tools, and methodology environment-related risk mitigation use of renewable energy sources; and eco-labelling of IT products Green Computing

IT’s Environmental Impact Electronic devices consume electricity - this then increases carbon dioxide emissions Waste - Manufacturing technology creates large amounts of waste, and used computers and electronics Health hazards - Using toxic materials that can harm our health can cause cancer e.g lead, cadmium and mercury Green Computing

IT’s Environmental Impact Cont.’s Pollution - Air, water, heat and noise pollution can all be caused by producing and using technology Green Computing

A Holistic Approach to Green IT Virtualisation Power Management Green IT Greening Data Centers Material Recycling Green Computing

Virtualisation The process of running two or more logical The process of running two or more logical computer systems on one set of hardware Applications e.g. VMware (ESX Server), Citrix (Xen) and Microsoft (Hyper-V). Green Computing

Virtualization Benefit Virtualization helps a company / enterprise lower power and cooling consumption, by reducing the number of machines and servers it needs. Virtualization on platforms can run across hundreds of interconnected physical computers and storage devices, to create an entire virtual infrastructure thus eliminating huge energy consumption in data centers Green Computing

Power Management IBM, Hewlett Packard, SprayCool, and Cooligy are working on technologies such as liquid cooling, nano fluid cooling systems, and in-server, in-rack, and in-row cooling new high-density servers, using hydrogen fuel cells as alternative green power sources Power Stacking HP Blade Chassis Green Computing

Material Recycle Green disposal. Refurbish and reuse old computers and properly recycle unwanted computers and other electronic equipment Donate all equipment's if not of use Used appropriate recycling agents to recycle Green Computing

Greening Data Center use a synthetic white rubber roof, paint, and carpet that contain a low volatile organic compound (VOC) make use of natural light as well as green power electricity generated from solar or wind energy—to run the data center investing in energy management software to regulate power usage Green Computing

Benefits of greening IT decreases waste and can offer potential cost savings to organizations that reuse IT assets Reducing carbon and other GHG emissions Reducing energy and running costs Reducing the amount of space need for servers Green Computing

Benefits of greening IT Cont.’s Green Computing

Green IT Standards and Regulations Epeat assists buyers to evaluate, compare, and select desktop computers, notebooks, and monitors based on their environmental attributes Energy Star 4.0 Standard The new Energy Star 4.0 standard regulates energy performance of external and internal power supplies Green Computing

Green IT Standards and Regulations Cont.’s RoHS Directive The Restriction of Hazardous Substances in Electrical and Electronic Equipment Directive aims to restrict the use of certain hazardous substances e.g. lead, cadmium, mercury, hexavalent chromium, or flame retardants Green Computing
