Energy efficiency: small steps make a difference

We work to improve the energy-saving features of our hardware product portfolio to help our customers save energy. Use of electronic devices inevitably involve energy consumption. Microsoft is committed to reducing the direct effects caused by the energy use of our products, including battery chargers.

Microsoft devices comply with the EU Ecodesign Directive for Energy-related Products (2009/125/EC) and its implementing regulations when applicable ("Ecodesign Directive"). Our devices comply with the European Commission's Regulation for Standby and Off Mode Power Consumption for Electronic Household and Office Equipment, and U.S. federal and state energy conservation standards when applicable. Microsoft devices meet the US Department of Energy, California, and other regional and country-specific efficiency requirements.

We work to improve energy-saving features throughout our product portfolio, including the use of energy-efficient chargers, to help our customers save energy. Small steps make a big difference. All our devices come with power-saving standby settings. We have also introduced applications, features, and technologies (such as ambient light sensors, efficient Snapdragon™ processors, and OLED or AMOLED displays) to save energy.

All covered products meet the voluntary ENERGY STAR® standard.

Energy consumed by consoles

An important part of our business strategy includes reducing the energy consumed by our game consoles within a generation while maintaining the same level of gaming power. For example, since the launch of Xbox 360 in 2005, our engineering teams have successfully reduced standby power by a factor of 10 to less than three-tenths of a watt, resulting in a 60 percent reduction in energy use. Our development and compliance engineers ensure all our products meet regulatory requirements such as the Ecodesign Directive.

Carrying lessons learned from Xbox 360 forward, we continued our commitment to reduce energy usage through the design of Xbox One, launched in 2013. Xbox One provides eight to 10 times the processing power of Xbox 360. Despite this significant increase, the electrical power required for gaming is 30 percent less than that of its predecessor when it launched in 2005. Power needed for media play and dashboard is half that of the Xbox 360 at launch. The increase in efficiency results from scalable processor architecture that wasn’t available for the Xbox 360. Other efficiencies are gained by providing the user with choices about console functionality while in standby mode.

The European Commission has identified video game consoles, a “priority product group” to be covered either by regulation or a self-regulatory initiative to reducing greenhouse gas emissions. We worked with other console manufacturers to develop responsible requirements to achieve that goal. The agreement is called the Voluntary Agreement for Game Consoles ("Voluntary Agreement"). The resulting initiative is the form of a design specification for Xbox 360 and Xbox One.

This Voluntary Agreement is a joint commitment by the game console manufacturers, which is estimated to deliver collective energy savings in the EU of one TWh per year by 2020. This corresponds to the annual electricity consumption for more than 250,000 households.

Our current products fully meet the requirements in the Voluntary Agreement. In November of 2017, the Voluntary Agreement was reviewed by the Consultation Forum of the EU and found to be meeting its commitments to reduce energy usage, exceeding the original estimate of one TWh per year by five TWh per year.

Microsoft Surface computers meet the voluntary ENERGY STAR® standard.


ENERGY STAR® is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy aimed at saving money and protecting the environment through energy efficient products and practices.


By using ENERGY STAR qualified products and taking advantage of the power-management features of the computer, you can help reduce the consumption of electricity. Reduced electrical consumption can contribute to potential financial savings, a cleaner environment, and the reduction of greenhouse gas emissions.


For more information about ENERGY STAR, go to

  • Please reference Table 2 for the default power and timing settings.
  • To wake Surface from Sleep Mode, press and release the power button on your Surface.

Microsoft devices comply with COMMISSION REGULATION (EU) No 617/2013 of 26 June 2013 implementing Directive 2009/125/EC of the European Parliament and of the Council with regard to ecodesign requirements for computers and computer servers.

The battery[ies] in this product cannot be easily replaced by users themselves.

Sequence of steps for achieving a stable condition with respect to power demand


Do a shutdown from OS, not a hibernate

  • Turn system ON
  • Log into OS
  • You may want to disable some of the power scheme timers for sleep and screen off
  • Go to classic desktop
  • Wait 15 minutes for system to become stable and processes to settle
  • Start measurements


Description of how sleep and/or off mode was selected or programmed

  • Surface computers are hybrid devices and both have InstantGo to provide an instant on / always up to date experience and hibernate to preserve battery life when the device is not being used.
  • InstantGo is entered after 4 minutes of inactivity on battery, 10 minutes of inactivity on PSU and lasts for 4 hours of inactivity after which it enters hibernate.

Please reference Table 2.


User information on the energy-saving potential of power management functionality


Surface 3 and Surface Pro 3 are preset with a power plan that automatically balances performance with energy consumption. This plan will put the computer to sleep after 10 minutes of inactivity when plugged in. The screen is set at one half the maximum brightness level.


Surface 3 and Surface Pro 3 use about two watts while sleeping. You can reduce the power to less than 0.7 watts by shutting your Surface down after use. You can realize further savings while using by dimming the screen below the preset limit.
