Powering the cloud

Powering the cloud Global data centers = 1.5x NYC energy requirement Every time you upload a video, share a photo, email a friend, tweet your location or check your bank balance your web device talks to a data center. Rows of servers storing trillions of megabytes of infomation live in vast, energy hungry computing complexes that power the Web. The energy impact of data centers Data centers are responsible for about 2% of global carbon emissions today and use 80 million megawatt-hours of energy annually, almost 1.5 times the amount of electricity used by the whole of New York City. 1 Data Center = , 25,000 US houses By 2020, at current growth rates and without improvements in energy efficiency data centers will produce 359 megatons of co =48% uS cars Impacts of data centers Opportunities for efficiency A significant proportion of Servers 25% the average organization's IT budget is allocated Significant amounts of energy can be saved solely to data center operations.

Energy consumption per m2 In addition the average data center could Data center save up to $47 million in real estate costs by eliminating the space required by redundant AC power equipment. Office If the world's data centers 5. 1 Standby power batteries. switched to newly available DC power microchips and many other components inside supply technology, which is up to 97% efficient, the IT equipment run on DC power. Since today's data centers have AC power annual energy savings would be enough to infrastructures (like your power your iPad for a AC > DC very very long time: home or office) power has AC DC to be converted at 5 different stages within the data center. This means that 20% of the energy is wasted within a data center's electricity infrastructure. This produces carbon 70 million years emissions equivalent to driving to Mars and back Mars 700 times.

Reliability and availability are also improved through a reduction in power supply components.
