Across its portfolio of desktops, laptops and printers, Hewlett-Packard has over the last five years managed to reduce the energy its products need to operate by 50 percent.
HP announced the achievement last week at the kickoff of a touring program, Unlocking Your Energy, which opened in New York last week before traveling to San Francisco, Beijing, Hong Kong and London.
"We set a goal to reduce energy consumption of our products by 40 percent by the end of 2011 from 2005 levels," Engelina Jaspers, HP's vice president of Environmental Sustainability, said in a statement. "I'm pleased to report we've exceeded this goal, and that HP products today are, on average, more than 50 percent more energy-efficient than they were five years ago."
HP compared a number of products -- including DeskJet and LaserJet printers, Compaq personal computers and ProLiant servers -- and found that it had achieved a 50 percent or more reduction of energy used by the devices over models from 2005.
HP also extrapolated the energy savings that would accrue should all of the computers, displays and servers it sold in 2005 were replaced with newer models. Unsurprisingly, the savings are huge: Approximately $10.4 billion in annual energy costs and 40 million metric tons of CO2 emissions would be saved through such a switch.
HP's announcement came on the heels of its entry into the carbon and energy management software space last week, with the Energy and Sustainability Management Solution. The announcement also follows on years of green initiatives from the company.
