Assessing New Energy Technologies Using an Energy System Model with Endogenized Experience Curves

Artikel i vetenskaplig tidskrift, 1997

Most energy systems models treat reductions of technology investment costs exogenously. In these models, investments may be postponed until the costs become low. This model behaviour is unreasonable, since early investments are necessary to realize the cost reductions, a phenomenon known as the experience effect. We have developed a global energy systems model with endogenized experience curves, and have conducted a pilot study to demonstrate the new insights which can be obtained with the model. In this initial application, we study the emergence of new energy technologies such as photovoltaics and fuel cells, competition between technologies and technology lock‐in effects
