Rudimentary depletion graphs

Based on numbers I could find via google I ran some relatively rudimentary depletion scenarios on World Oil and US Coal.

Cool, keep plugging away. People are reading them 
By the way, what are some of your thoughts on those charts and where did you get the statistics backing them?-

My thoughts on charts (in general) are that they really help illustrate points if done up properly.
Part of the learning experience is seeing just how hard it is to get numbers at all let alone accurate and reliable statistics to try and model a depletion of a reserve. I do enjoy the math, since it is fun for me to look at the recurrence relations and derive the equations to plot such graphs. Not everyone likes math though, so being able to draw more accurate pictures of different scenarios for folks who are interested in the topic is nice as well.

Nice work.
I really would be interested to see your coal graph include North American lignite and subbituminous reserves.

Here's a graph of global coal estimate, via The Oil Drum:
Of course, if CtL is widely used post-peak (and it probably will), coal depletion will be greatly accelerated.

It's a nice graph and very readable, but not done properly.

It's more than math, it's economics, which you completely ignored, resulting in an grossly inaccurate graph.
Y never equals 0, although it does approach zero.
If your graph was accurate, then you have just won the Nobel Prize in both Mathematics and Economics for proving the following:
2,500 - 3,000 is greater than or equal to 0.
