Energy-Demand

Total power consumption of around 31 GW. This amount if fully utilised would be sufficient to provide energy to all residential households in the United Kingdom, France or Italy 

A projected rate of increase in energy consumption of 19% into 2012 

An averaged total power to rack of around 4.05 KW with an overall racks profile of 58% under 5kW/rack; 28% 5kW-10kW/rack and 14% racks over 10 kW/rack.

Data center energy demands areprojected to grow in every market
The greatest increase in power demand is in market samples with greatest projected facility growth over the next 12 months, or where the major factor is supply to new builds. Greater focus on increased energy in major European  and United States markets indicates greater proportion of investment made in upgrading IT systems and support within existing facilities. In these markets a high adoption of efficiency strategies, IT architectures and perrack consumption that are already the highest in the world indicate a market situation where increased IT capacity can be achieved with a minimum of increase in the energy requirement.

Energy-Demand-Ranking

Table 1. Shows World power consumption growth ranking.

Energy-Demand1Projected increases in power consumption follow the pattern of investment expenditure, that is developed markets show lower percentage increase but larger actual amount of extra power required. The lowest ten markets are all developed – they mostly already have high density racks and are advanced in using monitoring, IT architecture and efficiency strategies to minimise the power increases required to increase capacity.

Energy-Demand2The growth end of the spectrum is populated by fast-developing markets and characterised by low initial rack densities, and high percentage growth. However here the types of developing market split with the largest growth markets – China and Brazil – each looking to require huge amounts of extra power.

Energy-Demand3In the middle of the list are three economies which indicate strong facility and investment growth but only average projected power increase – India, Mexico and Russia. Here concerns about energy availability and local power distribution networks create specific local challenges in meeting IT capacity requirements.

Energy-Demand4The one set of markets ‘out of position’ on this list are the Nordics – a developed market with already high server densities which indicates high power growth comparative to facility growth. This could be be linked to the development of sustainable power sources as a means of attracting inward data center investment.
