Infographic: 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 information 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 Servers 25% A significant proportion of the average organization's IT budget is allocated Significant amounts of energy can be saved solely to data center through improvements in server design and operations. (excluding software) management. In a typical data center some of these improvements could individually reduce impact by: Servers 27% Reducing power demand by 27% through virtualization, 5.75 million new servers are which reduces idle capacity. installed every year to keep up with growth in online services, yet approximately Taking 6,500 cars off the road 10% of installed servers are by using Energy Star compliant servers can reduce a data unused due to overly con- center's power consumption 6,500 by 82.000 megawatt-hours. servative capacity planning. Energy used to power Powering 2,500 US homes through better unused servers could offset the emissions of capacity planning. 6.5 million 6.5 million cars. 2,500 Servers are often oversized to cope with peak US demand, meaning that on average they run at only 20% capacity. Cooling Cooling Improving airflow management, using variable Computer equipment creates lots of heat speed drives for cooling fans and operating the Cooling makes up around data center within a slightly wider, yet safe 30% of total energy usage temperature range can reduce energy needs by in the average data center. up to 25%.

The payback time when retro- $281 million fitting a data center with state of art energy efficient cooling can be as little as 2 years. Infrastructure Data centers are big 2 years for payback 2013 Each year new servers take extra space. Data centers are increasing in footprint by 10% year on year. The world's biggest data centers occupy over 1 million square feet, big enough Infrastructure to house 17 football fields. These buildings use more than 100 times the Using a DC power supply architecture within a energy of a similarly sized building. data center can eliminate redundant equipment and reduce power losses in the conversion process by up to 20%. 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 Office AC power equipment. If the world's data centers 1. Standby power batteries, 5. switched to newly microchips and many available DC power 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 home or office) power has AC DC very very long time: AC + D C 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. 70 million years This produces carbon emissions equivalent to driving to Mars and back Mars 700 times. At 55mph that DC power infrastructure also provides easier would take 308.000 integration of photovoltaic solar panels, which years 700 generate DC power output. Reliability and availability are also improved through a reduction in power supply components.
