World goes dark in support of Earth Hour

The term "Earth Hour" hit fever pitch on Twitter just moments ago, trending all the way up to No. 1, as the first time zones in the world started turning off its lights in support of the energy-saving movement.

Earth Hour began in 2007 in Sydney, Australia, as "2.2 million homes and businesses" participated, per EarthHour.org. Last year, the movement went global, "with 50 million people switching off their lights" from San Francisco, USA, to Rome, Italy.

Earth Hour 2009, set for today (March 28, 2009) from 8:30-9:30 p.m. local time, officially kicked off with this tweet:
