Overcoming the lock-out of renewable energy technologies in Spain: The cases of wind and solar electricity

This paper applies an evolutionary economics framework to analyse the factors leading to lock-out of renewable energy technologies (RETs). The cases of wind and solar photovoltaics (PV) in Spain are empirically analysed. The paper shows that a wide array of interrrelated factors (technoeconomic characteristics of technology components, system-level infrastructure and institutional factors) can create both barriers to the wide diffusion of RETs and can also be drivers that foster an escape from a lock-in situation. Based on this analysis, the paper suggests several policy measures which may help to overcome the lock-out of promising renewable energy technologies. (c) 2006 Elsevier Ltd. All rights reserved.
