Below is an interesting video entitled:
Reasons to Believe: Lightbulbs (with Susan Sarandon)
It's time to act, time for an Energy [R]evolution. Greenpeace has called for leadership on climate change with the launch of our Energy Revolution. We are highlighting how simple changes can make a big difference, on exactly how much energy can be saved by banning traditional lightbulbs - proof that small changes can make a big difference towards addressing climate change!
With thanks to Susan Sarandon for providing narration.
