There are those who think that Earth Hour is a waste of everyone's time, that it doesn't save a watt of energy, and that it is anti-technology. The numbers prove them wrong; it does save a few kilowatts at the generating stations, although we are burning quite a few candles.
But nobody can deny that a lot of people are having a lot of fun in the dark, celebrating in a good cause. There is nothing wrong with that. Here are images of Earth Hours past.
