So that was earth hour.
An hour where millions of people turned off one light, photographed the sky, video, blogged and twittered about it.
The total savings in electricity won’t have that big an impact on our total use of energy, but that’s not the point.
The point is that millions of people around the world voted for the planet, actively signed up their support for the planet in the face of an environmental crisis.
This comes as I finish reading Seth Godin’s book Tribe, and the Earth Hour is a great example of someone with little power building a tribe. A tribe with a purpose who are prepared to take action.
