Talk:World energy resources

So, what exactly is a ZJ? What units is that graph at the top right supposed to represent? This article is incoherent to somebody who doesn't already know the information it will discuss.

In the nuclear fission section, the author claims to get this information: "The International Atomic Energy Agency estimates the remaining uranium resources to be equal to 2500 ZJ." from this source ' "Global Uranium Resources to Meet Projected Demand: Latest Edition of "Red Book" Predicts Consistent Supply Up to 2025". International Atomic Energy Agency. 2 June 2006. Retrieved 2007-02-01.', but the link only mentions uranium resources lasting 2500 years (not 2500 ZJ remaining). Was this just a typo, or does the full "Red Book" quote 2500 ZJ? Tprentice (talk) 21:24, 26 July 2012 (UTC)[reply]
