Shell has a great website (Energize your future) that includes an education section - check out the Adventures in Energy Flash animation that takes you through the energy cycle. The games and and quizzes are great. Try the technical quiz to find out which technical career is best for you.
This website sent me on a path exploring Energy education websites - I will share these with you this week.
