In the wake of the COP21 conference in Paris global warming and a transition to an alternative energy supply remain as some of the most central issues on the political agenda. In order to achieve the newly formulated goals nation states need to adopt ambitious policies within multiple policy domains. Renewable energy policy is one of the most important policy domains for the achievement of the COP21 targets. However, little is known about the factors leading to an extensive renewable energy promotion, which might be central for reaching the goals. To better understand the specific aspect of renewable energy promotion and the climate-environment-energy nexus as a whole we ask what might explain regional differences in the promotion of renewables within one single but federalist country?
To answer those questions, we focus on the Swiss case. Switzerland is interesting for several reasons: Switzerland knows a strong climate mitigation policy since the beginning of the 20th century. This might create an overall favorable context for the promotion of carbon-free energy supply. Second, and after the Fukushima accident in 2011, the Swiss government decided the nuclear phasing out. This decision should give renewable energy supply a particular boost - something that still has to be proven. Finally, Switzerland is a federalist country with 26 sub-national constituencies (so-called cantons). Energy policy is mainly in the cantons’ competences.
As of today the 26 Swiss cantons have put very different effort in the realization of this proclaimed energy turnaround in general, and in the promotion of alternative energy supply in particular. This makes an ideal case study to investigate what different factors and combinations of factors might explain differences in the promotion of renewables in a federal system. Based on the multiple streams approach we derive driving factors from the problem, process and solution stream. Additionally, major institutional factors such as different policy stiles as well as the unexploited potential for alternative energies and the heterogeneous geographic conditions in the various states may be relevant and are therefore considered in our analysis.
Applying fuzzy set qualitative comparative analysis (fsQCA), conditions in the 26 sub-national constituencies concerning the promotion of alternative energy supply are investigated. We adopt thus a set-theoretic perspective and analyze whether given sets of cases stand in a superset- or subset-relationship to each other.
We expect the promotion of renewable energies to be linked to specific and complex combinations of context factors. Following the multiple streams approach we assume the combination of high problem awareness in the public, a high feasibility and the absence of a strong non-renewable energy lobby to be a condition for a strong financial promotion of renewable energies. Concurrently we imply causal asymmetry and argue that a strong focus on nuclear energies in the current energy mix and the lack of a significant unexploited natural potential for renewable energies leads to a weak financial support for renewables. With these insights we will contribute to the clarification of the climate-environment-energy nexus and extend the multiple streams approach for future applications.
