Exploring cultures of evidence in energy policymaking in the UK, Germany, and the Netherlands

This paper explores different “cultures of evidence” in energy policymaking in the UK, Germany, and the Netherlands. The urgent energy system transformation needed to respond to the climate crisis depends on policies informed by technical and engineering expertise, and particularly energy modeling. Such expertise had traditionally been poorly represented in the energy ministries of the Dutch, German, and UK governments. There is limited understanding of how policy advisory systems have evolved to respond to these emerging evidence needs. This paper presents a framework for describing how cultures of evidence differ, and applies this to a comparative study of energy policymaking in the UK, Netherlands, and Germany. I show clear differences in how evidence is understood and used. The Dutch and German governments have sought technical and modeling evidence from consultants or independent agencies. In doing so, the Dutch and German ministries appear to place stronger value on the “independence” of such evidence, while the UK system builds credibility through adherence to formal procedures. A second clear difference in the cultures of evidence relates to different beliefs about the extent to which expert knowledge can be impartial and value-free. The cases suggest that different cultures of evidence have coevolved with each country’s institutional history and shaped the energy policy advisory system.
