Patriot's Energy Pledge
This site uses Revolutionary War imagery to encourage Americans to take the Patriot's Pledge. The front page offers the pledge form with simple steps to reduce oil usage and the real time counter of barrels saved. Each pledge item had an associated savings over the course of a year.
Returning users are greeted by name and reminded of their personal pledge items. On the other side of the page, they are encouraged to invite their friends to the site to take the pledge.
