At our house we set the timer to remind us to turn on all the visible out side lights. We have multiple security lights on the garage and the barn that come on when the sun goes down. My friend George Rebane has evidence that he turned on his lights for Earth Hour at Ruminations. I should have done the same, but was working on a sea level issue in R and forgot. I am glad I set the timer to remind me to turn off the outside house lights at 9:30.
The real question is did it Earth Hour make a difference one way or the other?
Roger Sowell had a good idea, he download the the graph below from www.caiso.com, the California Independent System Operator. CAISO is in charge of receiving power from power generating plants, and distributing the power throughout the state grid to the various end users.
Now compare the graph from Saturday 3/28/09 to the one on Sunday 3/29/09 shown below, note the similar slopes during the same time period. Note that annotations were added by Anthony Watts on both graphs.
There was no apparent decrease in the power load throughout the state, from 8:30 to 9:30 p.m. No step changes, nothing, nada, zip, zilch.
There you have it, scientific data showing that the Earth Hour was a total bust in California. If you look close, you can see a little bump up above the forecast demand, which tracked very closely with actual power consumed prior to the witching hour 8:30 to 9:30. But, it is clear that power consumption did not drop, it stayed up. Maybe all those protesters forgot to turn off the lights.
