According to a Pike Research report, the implementation of cloud computing and cloud services now have the potential to reduce worldwide data centre energy expenditures by 38% by the year 2020, compared to a business as usual scenario.
“The growth of cloud computing will have a very significant positive effect on data center energy consumption,” says senior analyst Eric Woods. “Few, if any, clean technologies have the capability to reduce energy expenditures and GHG production with so little business disruption. Software as a service, infrastructure as a service, and platform as a service are all inherently more efficient models than conventional alternatives, and their adoption will be one of the largest contributing factors to the greening of enterprise IT.”
The reduction will drive total data center energy expenditures down from $23.3 billion in 2010 to $16.0 billion in 2020, as well as causing a 28% reduction in GHG emissions from 2010 levels, the research firm said.
That’s not all, as part of its cloud computing adoption scenario, Pike Research forecasts that data centers will consume 139.8 terawatt hours (TWh) of electricity in 2020, a reduction of 31% from 201.8 TWh in 2010. This also represents a significant decrease from the 226.4 TWh that would be consumed by data centers in the firm’s BAU scenario. In other words, the data centers will feature much higher capacities, while consuming much less power – at least per unit of traffic or compute cycle.
