Do Renewables Make for Cheaper Electricity?

Do they or don’t they? It’s the perennial argument, and I claim that it shouldn’t be difficult to show that they do not. However, I have to admit that there is not a readily available and convincing set of data or a graph that will make the case. The problem is made difficult because there are so many factors that have some impact on electric service prices. Whatever simple analysis one tries to make on the basis of plotting one factor against price contains mostly noise.
