Did you know if you drink a energy drink you consume energy? You should see the video and also pass it on to all youngsters to see. Along with this you should check out this Wikipedia page of John Hansen Scientist at NASA http://en.wikipedia.org/wiki/James_Hansen. See the Shashi Bellamkonda Flickr Feed on Dr Saul Griffith's talk.
I also saw a nice powerpoint on energy from Rutgers University ww.physics.rutgers.edu/~lath/Piscataway_2003.ppt
