I like info-graphics. Here is one from Good magazine about energy:

I think what I like most about infographics is that they leave me asking more as well. For instance, I wonder how representative their assumed hydroelectric production rate is? I wonder how much carbon dioxide is released by  714 pounds of coal burned. I also wonder why we can’t all agree to use the SI …178lb = 80.7kg; 143lb = 60.86kg; 0.035lb is less than 200g.

I hope you find this thought provoking and it makes you go and find out more numbers on this topic.
