China is the world's top consumer of coal, and accounts for more than 50% of the world's total consumption of coal.
Seems that you're in violent agreement. China is so large that it tops most metrics you throw at it, even when we consider them contradictory.
People keep forgetting in all the China-posting that China is a country of 1.4 billion people, approximately 256 times the size of the Irish population, and therefore it's not really surprising when it tops a "top consumption" or "top production" list of any kind.
(second most populous after India)
Alternatively, if all Ireland was a city in China, it would not be in the list of top 50 cities by population.
