Here in Phoenix, I’m waiting for 8 pm to roll around, so I can power down. It’s Earth Hour, time to turn down the energy consumption, if just for an hour. This is a great idea, very playful, and people are getting into the spirit by getting the candles ready, camping out in the back yard, and so on. And the lesson is right out of WWO: c’mon, there’s life with less energy, and we can make it a good life if we act rather than react. OK, that’s enough – it’s so cool I’m powering down ten minutes early. See you in the dark!
