4. www.themegallery.com Guesstimating Carbon Footprints  An Average server has nearly the same carbon footprint as an SUV doing 15 miles to the gallon. *  Google is estimated to have 500000+servers alone and growing rapidly  It also has nearly 40-60 data centres. To give an idea of the size of a data centre, here are a few examples of google itself  Google is building a new datacentre in The Dalles, Oregon. That is going to 34,000 square feet spread across two buildings. The company owns 20 acres of land at The Dalles and has options to buy more  Another new datacentre is being built at Council Bluffs in western Iowa. Google has purchased a staggering 1,185 acres of land at the site.  A third new datacentre is being built in Berkeley County, South Carolina. It is on a 520-acre site  A fourth new datacentre is being built at Lenoir in North Carolina  A fifth one is being built in Pryor, Oklahoma  Google has over 100000 drives for storage  Therefore google by far contributes to most carbon emissions in the IT industry.  It may even have the biggest carbon footprint on earth Source: Techworld.com

5. www.themegallery.com Ideas to reduce them  Sea powered data centres*  computing centres are located on a ship or ships, which are then anchored in a water body from which energy from natural motion of the water may be captured, and turned into electricity and/or pumping power for cooling pumps to carry heat away from computers in the data centre *Google Patent: September 2008
