Well, Earth Hour was marked in San Francisco last night with a whole mess of people scrambling up Twin Peaks to see the lights go out at 8:30 PM. Some expected the whole city to go dark, but that’s not the way it works. This photo of the Bay Bridge from last year shows how things operate.
See what Earth Hour 2009 looked like for yourself with a this time lapse video – City Hall, normally quite a bright building at night, is on the left. Watch it flickr off about ten seconds in. Click to play.
Now here’s the view from Twin Peaks just after 8:30 PM. City Hall is the black void at the bottom. You can see that the people at Pepsi, 505 Montgomery and the unnamed dome to the right got a late start on EH09 (assuming they participated at all). Click to expand:
See you (dimly) next year!
After last night’s Earth Hour of partial darkness from 8:00-9:00 PM, the lights on the “architectural necklace” of the western span of the San Francisco-Oakland Bay Bridge came back to life on the north side first. (Unfortunately, didn’t get a look at the troubled eastern span last night – it was probably darkened also.)
The lights on the suspension cables of the western span of one of the busiest bridges in the world are just for decoration, not for navigation safety or whatever. Pretty. They sure make a big difference to the look of San Francisco at night when they are turned off.
Question: Turning off these decorative lights for an hour saves enough electricity to power Al Gore’s house (his actual house, not his San Francisco condo in SOMA that’s visible on the right) for how many minutes?
Answer: About 13 minutes. Let’s work on that math, after the jump.
