8:30-9:30 pm March 30, 2012 PST in Sherman Oaks California is the Earth Hour. The goal is to switch off as much electricity as possible during this one hour. During Earth Hour use candles, sit by a campfire or just meditate in the dark. The objective is to use as little power from the grid as possible.
