Thanks for that. One of the beauties of this group is that it's
virtually all high quality.
Having read the presentation now (it took ages with my dial-up
connection to download), I'd say two things, one it's a nice
presentation with lots of interesting data,
and two
it's heavily out of date.
Chinese statistics claimed a fall in coal production in the 1990's.
There are people who claim that this fall wasn't real, and due to bad
Chinese statistics. What I've heard specifically is that the Chinese
government was less than impressed with the safety record of small
mines and that local government officieals therefore hid the
production of many small mines.
I don't know what the truth of that is, but the fall does appear a bit
strange in the face of (according to official statistics) pretty good
economic growth over the period. Maybe Chinese economic growth wasn't
actually all that grand during the Asian crisis and the coal
statistics are real. Maybe there was a big efficiency improvement.
But, over the last five years Chinese CO2 emissions have supposedly
doubled due to doubled coal production, and energy consumption's
supposedly grown as fast or even fast than GDP.
I've got some healthy skepticism when looking at Chinese statistics,
but taking the official pronouncements of the Chinese government and
guesstimates from other sources, it very much looks like the fall
suggested by that powerpoint was a temporary aberration.
