Energy Efficient Products
Energy Star

ENERGY STAR is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy helping us all save money and protect the environment through energy efficient products and practices.

Lenovo offers a full complement of ENERGY STAR® qualified notebooks, desktops, workstations, monitors, and servers.  Click here for instructions on how to access ENERGY STAR information for Lenovo products.

ENERGY STAR availability within Lenovo's current offerings includes:

  • Approximately 98 percent of all notebook platforms[1]
  • Approximately 71 percent of all desktop platforms[1]
  • Approximately 92 percent of all workstation platforms[1,2]
  • Approximately 50 percent of all server platforms[2]
  • Approximately 96 percent of all monitors[1,3]


 Additional highlights include:
  • energy•  In December 2013 the US EPA recognized two Lenovo monitors -- ThinkVision LT2223d Wide and ThinkVision LT2452p Wide among its ENERGY STAR Most Efficient 2014 designation. The ENERGY STAR Most Efficient mark is an extension of the ENERGY STAR® brand and is designed to recognize and advance the most efficient products among those that qualify for the ENERGY STAR. This recognition is for specific categories and awarded for a specific year. The goal of this effort is to encourage new, more energy-efficient products into the market more quickly by targeting early adopters.

  • •  All Lenovo newly released ENERGY STAR qualified Desktop and Notebook platforms, and Monitors exceed the current applicable ENERGY STAR power consumption requirements (by 25% to 60%).  Many Lenovo products significantly exceed ENERGY STAR requirements.  For example, the M72e Tiny desktop exceeds the ENERGY STAR specification by 72%.

  • •  The majority of Lenovo ThinkCentre desktops meet the latest standard of the China Energy Conservation Program (CECP) and 30% exceed this standard.  All ThinkPad notebooks meet the latest standard of the CECP and 10%-20% exceed this standard.  All Lenovo IdeaPad and Printer products meet the latest standard of the CECP.  All Lenovo Visual products, All-in-One products, and new models of specified notebooks and desktops will meet Grade 1 of the China PC Energy Labeling Standard when it becomes effective.

  • •  All Lenovo Class A external power adapters meet and exceed US (Dept of Energy, California Appliance Efficiency Program, etc.) and Worldwide (EU ErP, Australia MEPS, etc.) energy efficiency requirements. All Lenovo external power supplies achieve Level V rating on the International Efficiency Marking Protocol for External Power Supplies.  Lenovo also continues to investigate and implement design changes which improve both overall and operating efficiencies for newly released power adapters.

  • •  Lenovo is a leader for the electronics industry in advocating for energy efficiency in China and is leading the development of the China Energy Efficiency Standard for PCs, the China Green PC Standard, and is very active in numerous energy efficiency work-groups, associations, and initiatives, including the Visual China Energy Efficiency Standard update, the China Environmental Labeling Program, the Energy Saving Work Association of the Chinese Institute of Electronics, and the China Energy Conservation Program.  Lenovo collaborates with other manufacturers and participates in a number of industry workgroups focused on existing and proposed global IT product energy efficiency policy, regulation and requirements. The current focus and activities includes ENERGY STAR, US Dept of Energy policy updates regarding battery charger and external power supplies, Mexico Energy Law, Australia MEPS, China CEC and a number of other emerging protocols and regulations.


In May 2009, ENERGY STAR released a specification dedicated specifically to servers – ENERGY STAR Version 1.0 for Servers. Not long after, Lenovo announced that its ThinkServer line was the first in the industry to achieve both tower and rack qualification.

Power Manager

Lenovo’s Power Manager enables the simple and flexible management of your notebook and desktop power settings.  This innovative tool allows you to take control of your PCs power consumption which translates into annual power savings.  For example, business customers deploying ThinkCentre M58 Tower PCs can save $71 per year, per user, by enabling Power Manager, which translate into a smaller carbon footprint for your organization.[4]


Lenovo’s Power Manager, used in conjunction with Lenovo ThinkCentre desktop PCs, supports the centralized management of your company’s PC energy use via integration with LANDesk or Active Directory.   This advanced capability addresses one of the biggest challenges of IT operation professionals regarding the management of a distributed hardware environment. 


To learn more about energy innovations in Lenovo products, please see Lenovo's Energy Whitepaper.


[4] $71 is the cost saving based on using default settings of the Lenovo Energy Calculator comparing a ThinkCentre M58 Tower with Power Usage model of Business, Power Management Enabled against a ThinkCentre M52 Tower with the usage model of Business, Power Management disabled.  Results are based on a hypothetical typical customer scenario and your results will vary.)


Energy Calculator

The Lenovo Energy Calculator 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.


Product Carbon Footprint (PCF)

To learn more about Lenovo’s PCF strategy and initial calculated PCF for a typical Lenovo notebook, desktop and monitor, please see the paper Lenovo’s Product Carbon Footprint Strategy or visit Lenovo’s climate change website.


Solar Power

A solar panel power is available for Lenovo products. Please click here to be directed to the suppliers’ website for more details.
