Originally created by the WWF in Australia in 2007, it has grown quickly into events all around the world.
IMO, this is a good exercise for several reasons:
- Trying to turn off all power usage at home or at work is an exercise in awareness. It may surprise us how many appliances, outlets we take for granted. Turning then off in one exercise shows the aggregate effect.
- Having a community turn-off event like this can help demonstrate how much power we typically use during that hour. Each household's usage may not seem like a lot, but it all adds up. It is a great community awareness tool, and again, shows the aggregated impact of concerted efforts.
