Internet Explorer 10 is the Most Energy Efficient Browser

Microsoft has published a blog post that highlights that Internet Explorer 10 is and continues to be the most energy-efficient browser on Windows 8. The report was published on World Environment Day. As per the report of Center for Sustainable Energy Systems at Fraunhofer USA, the browser consumes upto 18% less energy than Google Chrome and Mozilla Firefox.

To prove their results, researchers tested the browsers on desktop and laptop computers in several common scenarios including:

  1. Browsing the most popular websites in the United States.
  2. Playing video content through Adobe Flash.
  3. Playing video content through HTML5 video.

The research team found in all the above scenarios, Microsoft’s proprietary browser – Internet Explorer 10 exhibited the lowest energy consumption. Here’s the graphical presentation of it.


Here’s what Microsoft had to say about its browser:

Switching to IE would save 120 million kWh in electricity and remove as much carbon dioxide as growing 2.2 million tree seedlings for 10 years. In today’s test, the researchers focused on a set of popular websites and benchmarks. They also played a number of Flash and HTML5 videos.

Microsoft says that if every Google Chrome and Mozilla Firefox user in the United States used Internet Explorer 10 on Windows 8 for a year:

  1. They would save over 120 million kWh in electricity!
  2. This is enough energy to power 10,722 households in the United States for an entire year.1
  3. This would eliminate the release of over 85,000 metric tons of Carbon Dioxide equivalent in greenhouse gas emissions.2
  4. This is the equivalent of reducing greenhouse emissions by consuming nearly 10 million less gallons of gasoline.
  5. This is equivalent to the carbon dioxide removed by growing nearly 2.2 million tree seedlings for 10 years.

Until now, several studies or research that was conducted only evaluated the energy consumption of residential computers. The impact that Internet browsers have upon computer energy consumption was never considered. The latest research commissioned by Microsoft sheds some light on his topic but I doubt if it will make many Chrome and Firefox users switch to Internet Explorer 10 just for one reason.

    I mean …… REALLY?!
    What good is the enerygy efficiency of a browser if your cpu is left on all day and is an energy hog? That’s like putting lipstick on a pig and calling it beautiful.
    I could caree less if a browser is energy efficient, what Microsoft has yet to admit is that it’s latest browser is not very compatible with a lot of websites and most webmasters are not running at the chance to make thier sites compatible with IE 10. Unless you are using Windows 8 which the browser works well on but IE 10 is pretty much a dog on Windows 7, I used it for a week on my system and went back to 9.

    Where have you been? Hiding under a rock? Gawd, you guys sound like a stuck record. Try IE 10 and see how it beats the $hit out of other browsers.

    This a serious question!

    Can you give me some links to websites where IE10 are not compatible.
    And describe to me where the problems are.

    I am not working for MS and It is not a provocation, it is serious.
    I am simply interesting.

    I would like to see some of this sites, and see what’s wrong
    And where it differ from FireFox(my preferred browser) and Chrome

    Microsoft is certainly looking after that compatibility issue, ED

  6. I have yet to see a website which does not render well in IE. If you could point me to one, maybe I could visit it. :).

    I could not even get into my own ISP webmail using IE 10, I had to use Firefox.
    Secondly, I uninstalled IE 10 over two weeks ago, I wasn’t keeping track of the sites it did not display correctly. I just got sick of it and reverted back to 9. IE 10 was not designed with Windows 7 in mind at all, lets face it IE 10 was designed for Windows 8 which it runs very well on, then all the Windows 7 users pissed and moaned so much that they wanted a new browser so Microsoft had to make it compatible with 7 but they half assed it, otherwise you would only see IE 10 on Windows 8.

    @Hemant – When Microsoft gets all the bugs worked out and I can get into my own webmail without a hassel I’ll consider using it, I’ll think about it again more towards the end of the year.

    Oh by the way, did I mention that IE 10 does not work on Windows 7 systems that are running 3rd party themes also.
