Using
BP's statistical review for 2004, the charts below represent the
rate of depletion of existing reserves if no new sources for coal
are found. They are show into the rate of depletion by continent
and the rate for the major producers that represent an 88% of the
world's total reserves.
Constant
2003 Level of Production
First
case assumptions:
Reserves
remain constant, no new sources of coal are found within the producer
country
Production
levels remain constant, never changing to levels above or below
2003's production for the producer country
This
scenario shows the rate of depletion for each country independently
if no new reserves are added to known reserves and present production
levels are maintained. After 100 years 47% of the world's present coal
reserves would remain and 47% of the major producers' present coal reserves
would remain, with only China becoming completely depleted.
1.95%
Growth Adjusted Level of Production
Third
case assumptions:
Reserves
remain constant, no new sources of coal are found within the
producer country
Production
levels increase 1.95% per year for each country starting from
2003 levels
This
scenario shows when each country/continent would independantly run
out of coal if no new reserves are added to known reserves as production
levels grow 1.95% to meet demand. Individual continents are depleted
in 100 years, with Europe and North America as the last significant
producers with reserves. The world's major producers effectively
run out of reserves in 100 years, except for Russia, Ukraine and
Kazakhstan which individually have reserves past 2003.

+ Depletion Adjusted Level of Production
Fourth
case assumptions:
Reserves
remain constant, no new sources of coal are found within the producer
country
Production
levels increase 1.95% per year for each country starting from 2003
levels, AND...
As
a producing country runs out of reserves its production is evenly
distributed amongst the remaining countries with reserves, adding
to their own production levels
This
scenario shows when each country/continent would become depleted if
no new reserves are added to known reserves, production levels grow
1.95% each year AND each country was forced to pick up its production
to make-up for the loss of production from depleted countries. Individual
continents are depleted by 2085, with Europe and North America again
as the last significant producers with reserves. The world's major producers
run out of reserves by 2090, with for Russia and the US as the last
significant producers with reserves.
