some reading or additional research on the web to tell about an alternative to using fossil fuels.  

For example, I saw, on a recent trip to WSU, that the college has installed something called green bikes.  This is a program where students rent  bikes from a locked station (with their credit card) and then return it to another location near their destination. I really enjoyed seeing this because it allows college students to use less gasoline and reach their destinations more rapidly. 

 Use evidence from your readings or do some additional research on the web to back up your idea or discovery. Teach us about something new.
