IE 10 is Most Energy Efficient Web Browser for Windows 8
Microsoft has announced that its Internet Explorer browser has been awarded the title of most energy efficient browser for Windows 8.
Microsoft took to its Exploring IE blog to brag about Internet Explorer and the fact that it's snagged the honor of being named the most energy efficient web browser for Windows 8. Of course, one could argue that it would be a bit embarrassing if a browser other than Microsoft's own won, but why argue? It was World Environment Day, let's not spoil it.
The Center for Sustainable Energy pitted IE 10 against Chrome 26 and Firefox 21, testing all three on desktops and laptops in several difference situations including browsing the USA's most popular websites, Flash video and HTML 5. The Center found that IE uses up to 18 percent less energy than Chrome and Firefox. Apparently, if every Chrome and Firefox user in the United States switched to Internet Explorer 10, the amount of saved energy could power over ten thousands American households.
"Power consumption is an important, but often overlooked, consideration in building a modern browser," said Roger Capriotti, Director, Internet Explorer Marketing. "It is one of our objectives to lead the industry in power requirements because the more efficiently a browser uses power, the longer a user can enjoy the Web on a PC, the lower the electricity costs and the smaller the environmental impact."
Mozilla's Firefox is currently on version 21 while Google Chrome is on version 27.

". . . the more efficiently a browser uses power, the longer a user can enjoy the Web on a PC, the lower the electricity costs and the smaller the environmental impact."
What? My PC operates on batteries? 10,000 homes if 300 million people would just use this one browser. Lol. Pathetic marketing.
Sorry I saw this line in the actual paper, so this means the entire paper is bunk. On top of that the tests were done manually. Deliberately adjusting your setup to reduce power draw while leaving others at default is total BS.
Another lame attempt by MS to manipulate PR rather than fix their software.
From web developer perspective, IE is nightmare. Compared to Chrome in development tools it is like old mechanical musical box compared to modern mobile phones. I would definitely choose Chrome or Firefox, or even Safari compared to IE.
Personally, I will still stick with Firefox, Opera, and Chrome for most of my browsing, using IE10 only as a fall-back browser.
They are both using rapid version numbers now. But it is true that IE updates very infrequently.
And propel IE10 past those two browsers in usage.
Obviously just MS propaganda.
