The usual answer is "because Fukushima shut down the nuclear industry, duh". But this is obviously wrong as when looking at the data. Much of the increase was between 2000-2010.

I wonder if it's due to the monopoly structures of the energy business shielding them from the changes that the rest of the world has been seeing. I wonder how much of the coal is used for electricity vs steel making etc.
