So you are citing an article that shows that there has been a 25% increase in the renewable mix in Germany while the economy was growing as supporting YOUR point?
Methinks you don’t understand what we are talkin about here. Either that, or you don’t get math.
Look at the headline, “progress lags”.
You throw enough money at anything and you will get some results. If you gave away all electric cars, more people would use them.
I suspect you didn’t read the article which points out the Germans are spending 4 times as much on their renewable energy program as the debt owed Germany by Greece.
Also note that 20% is less than 50%.
But you will probably just try another insult to distract the casual reader.
