Since 2007, Earth Hour has rallied people together from all over the world to recognize the reality of climate change. Last year over 7000 cities in 154 countries participated in Earth Hour. This significant gesture serves to start a conversation about our impact on the Earth and demonstrate in a very direct manner how individuals working together can make a difference.

The idea here is that on March 28th at 8:30pm local standard time, you look around you and turn off as many lights as you safely can for one full hour. Throughout the world as more and more people begin to turn off their lights, energy use is brought down and people start talking in the dark. This is the first action step and a great place to start (you never know what kind of conversation you could get into). But the real action lies in what you do next. Perhaps this is the moment that you start to think about your non-essential lights being on at all. As the sun starts to get higher in the sky, our need for lights on in the house can be reduced. Perhaps we don’t need to have that outdoor light on all night long or that lamp in the living room in the late afternoon?

What a sight to see, the city streets a little darker. Maybe your next thought is to question your office building’s light policy. Maybe you will make a point of talking to the sustainability committee or building manager to talk about installing motion sensors in the hallways for lighting. The repercussions of an awareness activity such as Earth Hour are where the impact lies. As a campaign, Earth Hour has grown exponentially in the last few years.

So, on Saturday, March 28th at 8:30pm Earth Hour creates an opportunity to start a dialogue with yourself about the impact of your actions.
