A promising energy source for a low-carbon energy future is wind. Policy-makers can attract wind energy development by providing attractive policy frameworks. This paper argues that apart from the level of ﬁnancial support, both the risks stemming from the regulatory environment (legal security, administrative process and grid access) and the ability to ﬁnance projects play a critical role in determining the attractiveness of the development environment. It sheds light on how project developers trade off these different aspects and to what extent the attractiveness of a certain policy framework increases with the introduction of speciﬁc measures. Conjoint analysis is employed to provide empirical evidence on the preference of wind energy developers in the EU and the US. The analysis shows that developers’ preferences are very similar across the studied regions and for different types of developers. Which policy measures could be most valuable depends on the speciﬁc existing environment. In some southeastern European countries, a reduction of administrative process duration may yield the highest utility gains, whereas, in the US, improvements in grid access regulation and an increase in remuneration levels may be more effective.
