Today was Bike/Walk to Work Day and seeing all the fun events to celebrate it around the Twin Cities Metropolitan area reminded me of the project seen in the video below.  It was done with the thought that:

...something simple and fun is the easiest way to change people’s behaviour for the better. Be it for yourself, for the environment, or for something entirely different, the only thing that matters is that it’s change for the better. (fun theory)

Events like Bike/Walk to Work Day intentionally build a community of people committed to doing something good for the environment, by limiting the amount they drive to work.  Others can become inspired by these actions in part because of how much FUN the people that participate seem to be having.

Think about the community you live or work in.  What are some things that could be done to improve the energy efficiency or limit your carbon footprint?  How could they be made fun?
