It's not easy being green--except for today. It's Earth Hour! So what's the deal with that? The World Wildlife Fund wants to create awareness of climate change, and is hoping we all start thinking about saving energy a little more.
So how to participate? Just turn off your lights for an hour tonight at 8:30 p.m., wherever you are. The Eiffel Tower is doing it, The Flamingo in Vegas, and Nashville too. Join in. It's easy, it's cool, and you can be all righteous and say you're green (you know you want to).
And find out about more ways to conserve energy here.
