Coal Limits

Excellent series Chris, thank you.
One addition to the limits to coal is that the 250 year supply is based on using it at the current rate! Obviously the rate has historically increased as you show. In addition the rate will increase further as we substitute coal for oil (where we can) and our energy consumption increases to extract lower grade resources.
