How is the world's oil like a rollercoaster?

My friend Stuart is a cartoonist, and has just completed a 120-page non-fiction comic. It's about the scientist M.King Hubbert and what he discovered about the way the world uses oil.

The comic takes about 20 minutes to read - which is much shorter than watching a documentary. As far as comics go, it may not be as action packed as you Batman or Spiderman comics, but at the end you'll feel a bit smarter and more knowledgeable about the world.

Now that we now what we've got, how will will best use it?
