Fight climate change with the flip of a switch!

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. Visit our new office space at 2548 Mission St., and sign up to help hand out CFLs. Give us a call at 1-415-643-LOSF for more information. >> more

Our city’s growing appetite for energy must be controlled to protect our planet from the effects of the climate crisis.

We estimate that turning lights out in San Francisco for even one hour could save as much as 15 percent of the energy consumed on an average Saturday night. >> Get Involved!
