Considering the number of people that get the email, the fraction of those that plan to act on it, the fraction of those that remember to do so, the magnitude of the load they can and do switch off, and the staggered times that the loads are switched off, I venture to say that the utilities will not even notice the "event". M. Peterson From: "Dennis Crawley" Subject: [EE] Shutdown the planet for 5min. Hi all, Someone is sending a mail spreading the voice that on August the 10th it would be a good idea to switch off all for 5 minutes.... Well, the idea apparently came from France, but I don't think it's a good idea. He says that we will save a lot of energy. Are the plants prepared for that "step"? What would be the reaction of that electricity plant? What would be the impact on transmission lines and transformers? If an EE can illuminate this with some figures, i'll appreciate it.
