The City of Fort Collins and Colorado State University have rallied with a group of leading businesses and foundations around a bold goal: to create the world's largest net-zero energy district.  Given all the aging homes in the district, they need the community's help.

Their community outreach effort is entitled the FortZED Energy Challenge. They divided the district into territories, gave each territory an animal mascot (marmots, elk, black-footed ferrets...), and then set out to convince everyone of the benefits of more energy efficient (and thermally comforable) houses.

The task required an online hub, so they set up a Wagn website to:

• gather pledges to reduce home energy
• organize energy-themed events
• recruit "Rangers" to spread the word
• send out targetted emails to everyone in a territory, all Rangers, etc.
• gather and share energy resources
• help the community share success stories

Not only did the community make great use of the website; they also helped to build it. Community members were invited to monthly "Wagneering" meetups where they could learn more about the tool and help expand its functionality.
