Last saturday was again the earth hour or planet hour. In the day itself and later it was funny to read many skeptics fight against it as here, or here more aggressive. There were favorable posts too.
My personal balance this year was worse than last year because we forgot about it until last 30 minutes, so I did not help much in spite of being convinced. And a more general balance? WWF shows a nice gallery of images that demonstrates at least some action arround the world.
Like last year I have collected the electrical demand data from REE (the official source), and even if the consumption was higher than las year, 31600 MW, it was 2000 MW lower than the previous saturday, more or less like the last year. Not so bad but not impressive as I would like, but this figure is only about a very small part of the world, we have to remember that this is a world-wide problem and a world-wide action in this case. Anyway, I agree with my ideas from last years post.
This is not going to change hour emission path but coordinated global citizen action is very important and could be very helpful to push the different policy makers to endorse the solutions we have, because it is possible to reduce hour emissions without going to the caves again.
