also, i would like to do some math and i would enjoy for someone to help me and tell me how wrong i am (as usual).

cartman, want to take a stab? (or others feel free):

so the website says 320 billion tons of low grade coal.

from statistics 320 billion tons of coal is low rank and 80% of the world's coal is low rank...that must mean 64 tons are high grade right? (320/20%)

so that is 64 billion tons of coal are high grade.

so now let's say 64 billion tons of high grade coal in the world...8 billion were burned last year, all high grade as low grade is "not good"

so 64 billion / 8 billion.......8 years. 8 years left of high grade coal........

at the same time, demand will continue to increase as 7 billion will become 10 billion people on this planet within 30 years (don't debate that part, let's say it stays the same just for debate sake)

okay, take a stab and tell me where im wrong.......
