It's Time for a New Turn of Phrase

... Doing a Krugman:

I cannot understand why Paul Krugman is held in such high esteem as an economist when he does not understand the simple fact that solar is not economic because it only supplies power when the sun is shining, not when the customer needs it. Maybe that is not in Krugman’s Economics 101 but it is definitely in Common Sense 101. In simple terms he may understand , when everyone supplies potatoes at the same moment to the market the product is not worth much - this Dr Krugman, is called a glut- maybe you have heard of the term.
