This document discusses how information technology (IT) can be made more sustainable through green IT practices. It provides examples of how various organizations have implemented virtualization, server consolidation, and cloud computing to reduce energy consumption and costs. Green IT practices like these can help double the energy efficiency of data centers over the next decade and reduce the rising carbon footprint of the IT sector. Going green not only reduces environmental impacts but also yields significant financial benefits through lower operating expenses.

7. 3 Ps Reporting Traditional Reporting New way of Reporting

8. Sources of Carbon in IT

9. IT’s Energy Breakup

11. Mobile phones carbon footprint will triple by 2020

12. Datacenters carbon footprint will rise more than five fold from 2002 to 2020

13. Lifespan of a mobile phone is about 1 year

14. Lifespan of a desktop or a laptop is about 3 years

16. There are not enough recycling facilities/ capabilities

17. Paperless office is a dream – Less Paper office must be attempted

18. Paper industry itself has huge carbon footprint

19. Uses

20. High energy

21. Chemicals

22. Water

25. YouTube needs 600 terabytes of storage to show the 100 million videos on its site

27. Estimated to be 30 billion tags (end of 2010)

36. Datacenter Efficiency Current global averages Target global averages

38. Best efficiencies are achieved at Full Loads

39. Most of the equipment runs at less than full load most ofthe times

73. So, it saves money first

74. And is Green too

76. Why Green IT - case3

77. Why Green IT - case4 Australian Dept of Defence (Gershon Report) Automatic log off and shut down of PCs reduced machine hours from 50000 hrs to 3000rs. The result was savings in electricity of over $5 million annually, with a decrease in GHG of more than 30000 tonnes annually (equates to 7 500 cars off the road per annum).

78. Why Green IT - case5 Dell A tool based switch-off/ switch on change over 50000 desktops across the globe helped DELL to reduce its energy consumption by 40%, translating to USD 1.8 m per year

80. Why Green IT - case9 Intel saved $US45 million by consolidating and replacing servers thus avoiding new data centre construction, and saved $US 95 million through Data Centre efficiency program.

81. Why Green IT - case10 TCS Going Paperless with online forms, business processes and workflows yielded a significant reduction in paper consumption for its operations. Measures to enforce double-sided printing, shared printing services and recycling printer cartridges led to a 28% reduction in paper consumption and a 68% reduction in printer cartridges in 2007 compared to the prior year.

83. Annual savings of US$ 70,000 on data centre maintenance costs
