I guess the biggest take-away for me ― not only from the  WSJ, but from Phys.org and AlphaGalileo ― is that "German emissions increased 1.8 per cent in 2012, with coal growing at 4.2 per cent".

It sounds like you think this is a temporary phenomenon and in the long run carbon emissions will go down as renewable power becomes more competitive and thus widespread in Germany.
