This tool uses actual energy calculations from internal Lenovo testing, in order to determine the energy savings on Lenovo desktops, notebooks and monitors. The energy savings are based on an estimated usage model for various configurations. Costs per kilowatt-hour are based on 2007 US dollar calculations. Rates by country are based on 2007 information published by the United States Department of Energy. CO2 emission factors are from the US Dept. of Energy's most recent data published in 2002. The tool allows you to select "Customize" and input your specific cost, CO2 emission factor and usage profile. Please select the "More Info" tab in the tool for more details on using these features. The Lenovo Energy Calculator provides an estimate and should only be used as a guide. Lenovo does not guarantee the savings as your company's usage may vary.
