Web Browser
The more efficiently a browser uses power the lower the electricity costs and the smaller the environment impact. While power might seem like a minor concern, with nearly two billion people now using the Internet the worldwide implications of browser power consumption are significant.
The following chart shows the power consumption of 5 most popular browsers- Internet Explorer 9, Opera 11, Firefox 4, Chrome 10 and Safari 4.
Most browsers are close to the system idle power usage, meaning they have little impact on power consumption. The exception is Opera 11 which is consuming about 5% more power than other browsers when idle.
But the leader of this chart is Internet Explorer 9, standard browser that comes with any Windows operating system. All computers in our lab have installed 4th version of Firefox browser. On our own experience, we can say that among students Firefox is more popular and preferable browser than IE, because of important features like speed, convenient interface, status bar and etc.
Since lab computers have both browsers-standard IE 9 and Firefox 6, we do not recommend making any changes, because such combination is already effective in terms of energy consumption.
