Learning From the Sun
This paper provides conclusion with regard to the use of 'Experience Curves' for energy policy making. It states that it is an interesting approach, but that such an analysis should be done with much care. For the historical analysis the availability of reliable and firm data is essential. The concept of the experience curve is simple, at least in principle. It states that, for every doubling of cumulative produced capacity of a product or technology, the cost for making it declines with a fixed percentage (learning rate). Historical statistical analysis can be used to define this percentage.
