To celebrate Earth Day 2011, the Greater Philadelphia Clean Cities Program and supporting-member AmeriGreen exhibited alternative fuel vehicles at Temple University’s Earth Fest, an annual festival showcasing all things green. With a Roush propane-powered pickup truck and a CNG van owned by Temple on display, we showed off AFV’s that are in-use and on the road right now.

The event brought thousands of people from southeastern Pennsylvania. Even though some of the younger kids couldn’t get interested by our clean-burning vehicles, AmeriGreen’s jars of biodiesel and soybeans got everyone’s attention. Check out the photos below!
