2. 2 2 Energy Facts Of all the potential electricity available in an energy source, only 30 percent reaches consumers An estimated 170 billion kilowatts are wasted by consumers each year due to insufficient power usage information US Datacenters and servers consumed about 670 billion kWh in 2008 with an estimated total electricity cost of $ 5.0 Billion DATA CENTER 100%30% 16% Generation & Distribution Cooling Power Supplies, UPS ServersSilicon Mission Critical Apps 1%.003%

3. 3 3 Where Does Power Go? IT Equipment = 30% Energy Equipments = 25% Cooling = 45% Total number of servers installed increased by factor 100 in one decade Number of server/processors per rack increased by factor 10 in ten years Power and thermal waste per server increased by factor 5 in ten years Source: APC View

4. 4 4 I.T damage to the environment Billions of KW/hrs Millions of Tons of CO 2 I.T Does as much damage to environment as Airline Industry 2% of CO 2 Emitted comes from I.T Industry For every 1 spent powering systems 0.5 to 1 spent on cooling I.T is the focus of GREEN lobby! Source: EPA Report

5. 5 5 Green Buildings IBM Example Enhancing existing buildings to be more energy efficient typically reduces total energy consumption by 20-50%... …while new green buildings have the potential to reduce energy consumption by 80% or more. Benefits Average achievable energy savings greater than 40%; Average payback of <2 years in Data Center Energy Efficiency assessments; Asset utilization rates increasing 2x-4x; Deferral of massive capital investments in new datacenter builds $1 energy savings drives another $6-8 operational savings on average Source: IBM Client Survey
