Multilevel assessment of diversity, innovation and selection in the solar photovoltaic industry
We undertake an empirical study of the solar photovoltaic (PV) industry using evolutionary-economic concepts. Experts regard solar energy as a realistic option for sustainable energy provision in the long run. We identify the innovation and selection forces that drive the changes in the solar PV industry. In addition, a quantitative analysis using diversity indexes is performed at four levels of the solar PV industry: countries, technologies, applications and companies. Richness (number of alternatives) and evenness are calculated in order to describe and identify the changes that have occurred over time at each level. Most remarkable is that evenness has increased at the company level and decreased at the other three levels. We draw a number of policy conclusions.
