Lights Out San Francisco

logo-dark.png Sydney led the way last March. San Francisco is going dark this Saturday night, October 20, from 8-9pm, to send a message on global warming:

Lights Out San Francisco is a citywide energy conservation event on Oct. 20, 2007. On this night, we invite the entire city of San Francisco to install one compact fluorescent light bulb (CFL) and turn off all non-essential lighting for one hour.

Word has it that both bridges and the Transamerica Pyramid are on board, and many restaurants will offer candlelight dining. There's also a great party going on in Dolores Park. Drop by. . .

But why just one CFL? And why wait for your city to catch on? Join in from afar.
