There are 40,000 coal lumps of 25 grams per tonne of coal.
That would put moving-information-across-the-net energy consumption at 3 billion tonnes (3.4 billion short tons) of coal in 2008. That's about 44% of world coal production in 2008.
If it took 1 lump of coal per MB in 2016, that would be about 29 billion tonnes of coal (32 billion short tons), or about 360% of world coal production in 2013 (latest date available).
