didn't participate in Earth Hour yesterday (because it's stupid), but it did get me thinking (which is probably the point). I am already somewhat energy conscious. For example I have things I use infrequently on separate power strips so that I can turn them off when they're not in use. This includes my PS2, Wii, and chargers for my DS and PSP. I feel like this is just common power management. Anyway, I wasn't home for Earth Hour and I thought about all that was running at home with no one there: 4 computers. I believe this is a remnant of the early Windows XP era, in which you always disabled the "Sleep" option on every computer you used. Anything could happen when a computer returned from sleep! The wireless card could have stopped working, all your programs probably crashed, and it was slow from some incorrectly stored memory from running programs. You might as well have turned the thing off, but starting a Windows machine still takes too long for me sinc...
