Today, Saturday the 29th from 8:30 to 9:30 PM is "Earth Hour" Wave of Darkness.
It starts in Singapore and circles the earth at 8:30 PM local time everywhere.

You can participate by turning out all non essential lights for one hour.

I'll have to set my cell phone to remind me this year. I always intend to participate, but then I forget.

Hey, if Las Vegas and others can do it, so can we,
So pass it on......
