When compared to Google Chrome and Mozilla Firefox, Internet Explorer 10 uses up to 18% less energy according to the study was conducted by the Center for Sustainable Energy Systems at Fraunhofer US for celebrating 'World Environment Day' today.
For their study, researchers tested the browsers on desktop and laptop computers in several common scenarios including:
· Browsing the most popular websites in the United States.
· Playing video content through Adobe Flash.
· Playing video content through HTML5 video.


In the above scenarios, Internet Explorer 10 exhibited the lowest energy consumption. In some scenarios such as playing Adobe Flash video on laptop PCs, it was 18% more energy efficient than Google Chrome, and it was 17% more efficient than Mozilla Firefox in playing HTML5 video. Consider that if every Google Chrome and Mozilla Firefox user in the United States used Internet Explorer 10 on Windows 8 for a year, they would save over 120 million kWh in electricity!
- This is enough energy to power 10,722 households in the United States for an entire year.
- This would eliminate the release of over 85,000 metric tons of Carbon Dioxide equivalent in greenhouse gas emissions.
- This is the equivalent of reducing greenhouse emissions by consuming nearly 10 million less gallons of gasoline.
- This is equivalent to the carbon dioxide removed by growing nearly 2.2 million tree seedlings for 10 years.
