I just posted an article entitled Large Scale Solar & Wind Power Not The Solution: Too Many Problems and Costs. There I make the argument that these unreliable and low-quality power sources are too expensive to be adopted on a wide scale. Where it is adopted on a large scale, in Europe, electricity prices are three times higher in order to provide the widespread subsidies for both consumers and conventional utilities. These alternative power supplies are not economic in a free market, especially when all the costs are included.
