Earth Hour โดย UlyssesBlue

Visit http://www.earthhour.org to pledge your support for Earth Hour and turn out the lights for 1 hour at 8:30pm March 26, 2011.

This year’s theme encourages people to 'go beyond the hour' to adopt a more sustainable lifestyle that uses less energy.
<p>
By using a dark theme on your computer, you will reduce its energy consumption. Choose a dark desktop wallpaper, use a dark home page, and adopt a dark Firefox persona (like this one).

This Earth Hour, go beyond the hour!
