First of all the 50% number is completely arbitrary. Why is it important to say half? Mathematically it is irrelevant. It is just a milestone. When that milestone is reached is just a matter of human habit.
It could just as easily be a Kilowatt hour number - but that would be meaningless to most people.
The point of the article and my point to begin with is that a low-carbon power system is clearly possible and Germany is leading the way.
I suppose your point is to say that it isn’t possible, but you have provided absolutely no basis for this whatsoever. Just unsubstantiated statements and a frequent use of profanity. Feel free to read my tagline in that respect.
