Earth hour

Tonight it's earth hour. That means that if you want to participate you need to shut down the lights in your house for one hour. By doing this you can save on electricity. If just one person does this it wouldn't be very effective but if more than 2 millions do this it's a whole other story. Lots of energy will be saved then.

But that is also the big problem. If everyone switches the lights back on at the same time there's a huge demand of electricity at that moment. And that can bring down the electric system for a few seconds or even a few hours. Because of that company's that provide electric ask everyone to not switch on the lights at the same time. They also ask you to only shut down the lights and not your complete house.

To keep all my data save I will shut down my computer this evening for once. Normally it's just in sleep mode, but this time I will power it down completely. You can never be sure enough.
