I've been assigned to do a project for my technology university class worth 30% of my grade. I have to choose an energy technology and prepare a research presentation about it. I've boiled it down to oil or coal, and want to focus in on the associated politics (whether international or local). Now I know that both these techs have a LOT of politics associated with them, and coal is interesting due to the new "clean coal" movement. Which do you think would make a more interesting topic to study? Thanks!
