"The Golden Gate Bridge, City Hall, Alcatraz and other parts of the city will go almost completely dark for an hour next month as part of a campaign to conserve energy and fight global warming."

"Organizers of Lights Out San Francisco are asking city residents and businesses to install energy-efficient bulbs and turn off all unnecessary lights for an hour on the night of Oct. 20, a Saturday. The goal is to save 15 percent of the electricity consumed on an average Saturday night."

"From 8 p.m. to 9 p.m. on Oct. 20, street lights and traffic lights will stay on in San Francisco, but City Hall and other municipal buildings will go dark, as will the historic prison on Alcatraz Island."

"Most lighting on the Golden Gate Bridge and Bay Bridge will be turned off, though roadway lights will remain on for safety."
