PC and server power management market to expand nearly fivefold by 2015
Much of the power currently consumed in IT operations is wasted, the clean-tech market intelligence firm finds. Many PCs are not switched off at night or over weekends, let alone when not being used during the day. Idle servers, meanwhile, continue to consume more than half the power they do when fully utilized.
Senior analyst Eric Woods said: â€œUsing power management settings on a single PC could save 746 kWh of electricity in just a year, which translates into savings of almost $77. Yet, in 2010, only a little over one-fifth of users employed power management settings effectively.â€
Most companies that operate servers and data centers have more pressing concerns than energy use - namely, availability and response times. Add in the complication of virtual server sprawl (many different IT functions distributed across many different servers, using virtualization software), and it is hard even to know which tasks servers are actually performing and how much power is being consumed.
In recent years, though, the power management software market has developed to include a variety of products with a range of functionality, from user-friendly tools to adjust PC power usage when machines are idle to complex virtualization management software that can, for example, dynamically shift computing loads between physical devices to maximize efficiency.
Such tools offer a fast return on investment for companies looking to save costs and reduce emissions. â€œThe degree to which IT is given a greater stake in reducing energy costs will be a significant factor in the development of this market,â€ adds Woods.
In September 2011, Google said that it consumed more than two billion kWh of energy in 2010. The internet giant said that it is planning to source 35 percent of its electricity use from clean power by 2012, either through direct purchases or by sourcing from utilities with clean power generation capabilities.
Googleâ€™s moves toward energy transparency reflect a broader trend among large businesses to cut down on energy use, carbon emissions, and energy costs, particularly through the more efficient management of power use by personal computers, servers, and data centers.
