Dell cuts PC energy use by 25 per cent since 2008

Dell claims its efforts to reduce the energy use profile of its desktop and laptop PCs has cut customers’ related energy costs by 25 per cent or more since 2008, making good on a commitment the company made to customers and the planet two years ago.

The 25 per cent reduction builds on major efficiency leaps some Dell models saw in previous years. Dell claims that energy efficiency of its OptiPlex desktops, for example, improved nearly 50 per cent from 2005 to 2008, and Dell Latitude laptops improved 16 per cent from 2006 to 2008.

Some Dell products significantly exceeded the 25 per cent improvement in the past two years. Dell’s OptiPlex 980 small form factor and OptiPlex 780 ultra-small form factor systems, for example, both achieve 48 per cent reductions in energy use when compared to their similarly-configured predecessors, the OptiPlex 960 and OptiPlex 760.

The company explains that it achieved its energy-efficiency targets by continuing to integrate Energy Smart technologies, including circuit designs, fans and power management features. The company also worked closely with its suppliers to further develop and deliver energy-efficient components, including processors, chip sets, power supplies and memory.

Additionally, Dell reports that it has completed its transition to LED displays across its entire laptop portfolio. Along with being mercury-free, LED displays deliver significant energy savings compared to the older standard cold cathode fluorescent lamp (CCFL) display backlight technology. Dell’s current 15-inch LED displays consuming an average of 43 per cent less power at maximum brightness. Dell estimates LED displays alone will save customers approximately £12.8 million ($20 million) and 220 million kilowatt-hours in 2010 and 2011 combined - the equivalent of annual CO2 emissions resulting from energy use of more than 10,000 homes - based on Dell internal analysis using U.S. EPA carbon conversion calculators.

“Organizations are recognizing the role IT can play in improving their productivity and reducing their environmental impacts,” says Mark Newton, director of Sustainable Business at Dell. “We’ve listened to them and are designing systems and solutions that dramatically reduce energy consumption, drive productivity and cost savings and help achieve a low-carbon economy.”

Based on worldwide unit sales beginning in 2005 with power-management features enabled, Dell estimates that OptiPlex desktop systems alone have helped customers save more than £3.32 billion and avoid approximately 50 million tons of CO2.
