• 14% of the carbon foot print of the global IT sector is accounted for by data center.
• They store large amounts of data.
• As at 2011, about 35% of companies were expected to surpass the IT capacity in 18 months.
• The average age of modern data centers is 9 years old, any data center older than 7 years is considered outdated.
