Dell Touts Energy Efficiency of Products
Dell says that since 2008, it has cut its customersâ€™ laptop-, desktop-related energy costs by 25 percent or more. The company achieved this by integrating energy-efficientÂ Energy Star, energy smart technologies, including circuit designs, fans and power management features, and transitioning to LED displays throughout Dellâ€™s entire laptop portfolio.
LED displays deliver significant energy savings compared to cold cathode fluorescent lamp (CCFL) technology. Dellâ€™s 15-inch LED displays consume an average of 43 percent less power at maximum brightness, resulting in cost and carbon savings. The switch is expected to save customers approximately $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 worldwide unit sales beginning in 2005 with power-management features enabled, Dell estimates that OptiPlex desktop systems have helped customers save more than $5.2 billion and avoid approximately 50 million tons of CO2. OptiPlex 980 small form factor and OptiPlex 780 ultra-small form factor systems both achieved 48 percent reductions in energy use when compared to their predecessors.
Dell currently enables desktop customers to lower energy costs by offering 80 PLUS Gold-certified power supplies. TheÂ 80 PLUS Gold specification exceeds the power-supply requirements in the EPAâ€™s Energy Star 5.0 standard for computers and requires the use of 80 percent or more efficient power supplies.
