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)

69. Simple maintenance

70. Less breakdowns

72. Huge reduction in carbon footprint

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

84. Reduced server count by 98%, achieving significant cost reduction

85. Reduced Total Cost of Ownership

87. Reduced cabling costs by 30 to 60 percent

89. LEED certified tier III datacenter

91. Reduction in cooling requirements

92. Reduction in maintenance costs

94. USD 13000 per annum on power and cooling

97. Additional ease of implementation and control over projects

98. Clients also benefit from lower TCO

99. Built twin Cloud Centers in a record period of 5.5 months with 30 plus IT services and 2 clients going live

100. More than 50 percent reduction in the effort cost

101. Around 80 percent reduction in the power demand by additional desktops and project specific servers

102. Reduction in OS build time to less than 30 minutes from 2-3 hours of manual installation time

106. Increased server utilization
