About Lights Out San Francisco

Background

You may ask: what good does one hour and one light bulb do? What do we hope to accomplish?

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. The ongoing benefits of installing CFLs in your house are also significant.

This savings will reduce carbon emissions into our air, preserve the natural resources used to produce this energy, set a positive precedent for the rest of the nation (as San Francisco so often does!), and result in ongoing reduced costs for the city, taxpayers, and businesses.

We’re asking San Franciscans to join together that night throughout the city to watch the lights go out. We’ll publish the energy-saving results on this website. We plan to make Lights Out San Francisco a recurring event – and part of a wider effort to promote energy-saving consciousness for our wonderful city.

We were inspired by a similar event recently held in Sydney, Australia, called Earth Hour. In Sydney, 2.2 million people participated. Their one hour of lights out meant that 24.86 tons of carbon dioxide were not released into the air – the equivalent of taking 48,613 cars off the road for one hour.

Of course, we’d hope for the same or better here.

How can you get involved? We’re glad you asked. Your support is critical to making Lights Out San Francisco a success.
